How to Verify a BPC-157 Lot: The Five Checks a Certificate Has to Pass

procurementUpdated 2026-11-04Reviewed by Mike Vance, Chief Research OfficerResearch use only
BPC 157 research vial with its LabFirst lot label
Short answer

To verify a BPC-157 lot, check that the supplier prints the lot on the vial, names the testing laboratory, shows the observed mass beside 1418.704 Da, and states net content in milligrams. Those five checks answer BPC-157 peptide where to buy better than any price. BPC-157 is a synthetic fifteen-residue peptide.

Key facts
  • BPC-157 is sold at LabFirst in 5 mg and 10 mg vials from $49; the 10 mg vial is cheaper per mg at $5.90, read November 4, 2026.
  • The identity reference for BPC-157 is 1418.704 Da monoisotopic (C62H98N16O22), PubChem CID 9941957.
  • A complete certificate carries identity by mass spectrometry, purity by HPLC with method and date, and net content in milligrams, all for the lot printed on the vial.
  • Each LabFirst lot is tested by an independent laboratory and the laboratory's own report is published for that lot at /coa/ and on the product page.
  • No approved medicine contains BPC-157 and no USP or NF monograph defines it, so no vial from any seller can be pharmaceutical grade.
  • BPC-157 left Category 2 of the 503A bulk substances list in April 2026 after its nominations were withdrawn; FDA's advisory committee reportedly voted 8 to 6 on July 23, 2026 to recommend listing it, and FDA had not adopted that recommendation as of November 4, 2026.
  • USPS Ground Advantage is free over $150 and a flat $15 below, US only; volume tiers are 10% at ten to nineteen vials of one size and 15% at twenty or more.

The short version for a buyer

BPC-157 is one of the cheapest research peptides to synthesize and one of the most widely listed, which is why the spread in quality between sellers is so wide. Buying it well takes five checks that fit on an index card: the lot on the vial matches the certificate, the testing laboratory is named and has its own lookup, the theoretical mass is printed and correct, the purity figure carries a method and a date, and net content is stated in milligrams. A listing that passes all five is worth comparing on price per mg. One that fails any of them is not worth comparing at all.

This page covers what the name refers to and the forms it is sold under, the sizes and price per mg LabFirst lists, what a certificate for the lot has to show, the five checks in order, how a LabFirst lot is verified, storage and shipping of the sealed vial, and where the compound stands with FDA as of November 4, 2026. It gives no guidance on use. Almost everything published on BPC-157 is animal or cell-culture work, and this page does not describe any of it as applying to people.

What is BPC-157, and what names does it sell under?

BPC-157 is a synthetic fifteen-residue peptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. The name abbreviates "body protection compound", the label the Zagreb group that first described it gave to a protein fraction from human gastric juice; 157 is the fragment number, not a lot or a strength. The same molecule turns up as BPC 157, BPC157, bpc 157 peptide, pentadecapeptide BPC 157 and, occasionally, the older name Bepecin. All of those are one sequence.

What is not simply the same is "BPC-157 arginate", a salt form some sellers market as a distinct product. It is the same peptide paired with arginine as the counterion. Its identity by mass is identical; its net peptide content per milligram of powder is not, and a certificate for it must still confirm the peptide by mass and state which salt was weighed. The same applies to capsule, nasal and oral listings: the molecule is the molecule, and a certificate that cannot tie a mass spectrum and a net content figure to the exact lot proves nothing about the form it is sold in.

The reference point for identity is public. PubChem lists BPC-157 as CID 9941957 with molecular formula C62H98N16O22, an average molecular weight of 1,419.5 and a monoisotopic mass of 1418.704. Those are the numbers a mass spectrometer is checked against, and the number a certificate must print beside the observed mass. Our guide on what BPC-157 is covers the chemistry at more length.

Why is BPC-157 so cheap to make, and why does that matter?

It is a linear peptide with no disulfide bridge and no unusual residues, which makes it inexpensive by solid-phase synthesis. That is why it is listed everywhere and why a vial's price is mostly the price of everything around the powder: the vial, the stopper and seal, the freeze-drying run, the laboratory test and the label.

Cheap to make is not the same as easy to make well. A fifteen-residue synthesis with three consecutive prolines produces deletion sequences, chains missing one proline, that run close to the main peak on HPLC. They are caught only by a laboratory that reports the mass of the main peak rather than just its area. A proline short, the mass reads about 1321.7 instead of 1418.7, and a chromatogram with a shoulder on the main peak is often that product at a few percent. Sellers who quote purity from a single unlabeled chromatogram are, whether they know it or not, quoting the wrong number.

How much does BPC-157 cost, and which size is cheapest per mg?

LabFirst lists BPC-157 in 2 sizes, 5 mg and 10 mg, from $49 to $59 a vial, priced per vial with the per-mg figure beside it so sizes can be compared without arithmetic. Per mg, the 10 mg vial is the cheaper at $5.90 and the 5 mg vial the dearer at $9.80, which is the usual shape: the packaging and the laboratory run cost the same whatever mass goes in.

BPC-157 at LabFirst, read from the product page on November 4, 2026: list price, price per mg and the two volume tiers
SizeOne vialPer mg10 to 19 vials (10% off)20 or more (15% off)
5 mg$49.00$9.80$44.10 a vial$41.65 a vial
10 mg (best per mg)$59.00$5.90$53.10 a vial ($5.31/mg)$50.15 a vial ($5.01/mg)

The volume tiers are per size, not per basket, and mixed sizes do not combine. USPS Ground Advantage is free on orders over $150 and a flat $15 below it, within the United States only, with same-day dispatch on verified in-stock orders placed before 12 PM Pacific on a business day. The cost per mg tool runs the same comparison across any two listings, ours or anyone else's, and the BPC 157 peptide for sale page shows the live price, the lot and the certificate state for each size.

Two price signals are worth reading on any listing. Any seller pricing 5 mg of BPC-157 at three or four times the cost of 10 mg is charging for a story, not for synthesis. And a seller offering 40% off with no lot change is not passing on a cheaper synthesis; the compound did not get cheaper this month. Either the margin was that large to begin with, or the lot is old and the seller wants it gone before the next stability question.

What should a BPC-157 certificate of analysis show?

Three tests answer three different questions, and a certificate is only complete when it carries all three for the exact lot on the vial.

Identity is settled by mass spectrometry. The number to look for is 1418.704 Da monoisotopic, or 1,419.5 Da average if the laboratory reports the deconvoluted average mass. An electrospray spectrum shows the doubly charged ion near m/z 710.4 and the triply charged ion near m/z 473.9. The certificate should print both the theoretical and the observed value, rather than a tick. "Identity: conforms" with no spectrum and no number has not shown you identity.

Purity is a separate question, answered by HPLC: how much of what came off the column was the compound. The figure is only interpretable with its method beside it (column, gradient, detection wavelength) and a date, which is what ICH Q2(R2) means when it asks that an analytical procedure be shown fit for its purpose. A percentage with no method and no date is a number somebody typed.

Net content is the third test and the one most often missing: the milligrams of BPC-157 in the vial, measured, against the size printed on the label. It also settles the counterion question. BPC-157 is supplied as the acetate or, less often, the trifluoroacetate left over from purification. TFA leaves the purity of the peptide alone and changes the net content: a vial labeled 5 mg that is 5 mg of peptide-plus-TFA contains less peptide than 5 mg of acetate salt. A certificate that reports net peptide content by amino acid analysis or quantitative HPLC against a standard settles it. Sellers who cannot say which salt they ship are usually reading a certificate a factory wrote for a different lot. The BPC-157 certificate guide reads a real one field by field.

Checking a supplier of BPC-157: the five checks, step by step

Every seller of BPC-157 says "third-party tested". The phrase costs nothing. These five checks take about four minutes per listing and separate a tested lot from a tested-sounding one.

  1. The lot on the vial is the lot on the certificate. Read the printed lot number, then open the certificate and match it. A certificate for "BPC-157" with no lot, or a lot that does not match, describes some other vial.
  2. The laboratory is named and has its own lookup. The report should come from a laboratory the seller does not own, with a search code you can enter on the laboratory's own site. Anything that exists only as the seller's own summary has not been verified.
  3. The theoretical mass is printed, and it is the right one. For BPC-157 that is 1418.704 Da monoisotopic; a certificate that prints a different figure has measured a different molecule or copied a template.
  4. Purity has a method and a date. An HPLC percentage should name the method and the run date. "99%+" with neither, or one date reused across every product a seller lists, is decoration.
  5. Net content is stated in milligrams. The label size is a claim; the certificate's net content is the measurement. Without it, the purity figure describes the powder, not the vial, and the price per mg you calculated is fiction.

Red flags on a BPC-157 listing

  • "BPC-157 peptide 99% purity" with no lot, no method and no date. The number describes a chromatogram somebody once ran; without a lot it cannot be tied to the vial in the listing.
  • "Arginate" sold as a different, better product. It is the same fifteen-residue sequence with a different counterion, and the certificate must still show the peptide mass and a net content that accounts for the salt.
  • An HPLC trace but no mass spectrum. Purity without identity is meaningless for a peptide whose deletion sequences run close to the main peak; the trace can look clean and still be the wrong molecule.
  • "Pharmaceutical grade" or "USP grade" BPC-157. There is no USP monograph for BPC-157, so no lot can conform to one. The phrase tells you the seller either does not know that or hopes you do not.
  • "FDA approved" or "now legal to compound". Neither is true as of November 4, 2026; see the regulatory section below.
  • Copy that describes effects in people, recovery, healing or any outcome. A seller writing that is outside research-use-only boundaries, and its documentation should be read in that light.

How do I verify a LabFirst BPC-157 lot?

Verification runs through the testing laboratory, not through us. Each lot is sent to an independent laboratory for identity by mass spectrometry, purity by HPLC and net content, and the laboratory's own report is published for that lot at the certificate index and on the product page. Until a lot's report is attached, the product page says "pending verification" against that lot and makes no purity claim; the price stands and the report goes live the day it arrives.

The lot is printed on the label and encoded in the QR patch on its right-hand side; scanning it opens that lot's record. The product page reads the live stock feed on load, so the lot and certificate state you see when you order is what ships. Our guide on how BPC-157 identity is confirmed explains what the mass spectrum proves that purity cannot.

How should BPC-157 be stored, and how does it ship?

Sealed and lyophilized, BPC-157 is a stable white powder: keep it refrigerated at 2 to 8 C, out of light, and it stays as it left the laboratory for the shelf period on the certificate. It has no disulfide bridge to scramble and no methionine to oxidize, which is more than can be said for most of the catalog. The practical risk is water. A vial opened and re-closed at room humidity pulls moisture into the cake, which then clumps, discolors and no longer weighs what the label says. The BPC-157 storage and stability guide covers the four levers that decide how long a sealed vial holds.

Orders ship within the United States by USPS, Ground Advantage free over $150 and a flat $15 below it, same day when placed before 12 PM Pacific on a business day; the shipping page states the cutoff, the carriers and what is and is not promised.

The record a laboratory keeps on arrival is short and it is what makes the certificate usable later: the lot number as printed on the vial and the certificate's accession or search code beside it; the date received and the condition of the seal; the storage location and temperature it went into; the number of vials, and later the date each one was opened and by whom. A vial with that record behind it can be traced from the bench to the laboratory report in one step. Without it, the certificate is a document about a vial that can no longer be identified.

What is the regulatory status of BPC-157 in 2026?

No FDA-approved product contains BPC-157, and there is no USP or NF standard for it. That second point matters when judging suppliers: with no official standard, there is no rulebook saying what an acceptable batch even is, so every purity figure rests on the supplier's method and reference material.

The compounding question has moved during 2026 and is still open. FDA placed BPC-157 in Category 2 of its 503A bulk drug substances list, the group that may present significant safety risks, in 2023. In April 2026 it moved off Category 2 after the nominators withdrew their nominations; FDA's page now lists it among substances nominated but withdrawn. Leaving Category 2 did not put it on the 503A bulks list.

FDA then took BPC-157 (free base) and BPC-157 acetate to its Pharmacy Compounding Advisory Committee on July 23, 2026, with the agency's briefing document proposing that neither be added to the list. According to published reports of the meeting, the committee voted 8 to 6, with one abstention, to recommend adding BPC-157 to the 503A list. That recommendation is advisory. As of November 4, 2026, FDA has not published a decision adopting it, and any change would go through rulemaking before a pharmacy could compound it lawfully.

BPC-157 is not a scheduled controlled substance in the United States. Our guide on whether peptides are legal covers the general position. FOR LABORATORY AND IN-VITRO RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION. LabFirst sells BPC-157 to laboratories and researchers as material for in-vitro work, gives no guidance on use, and ships only against that understanding.

Bottom line

BPC-157 is one fifteen-residue sequence sold under half a dozen names. Buy it against a certificate for the lot printed on the vial, one that shows the observed mass beside 1418.704 Da, a purity figure with its method and date, and net content in milligrams. The 10 mg vial is the cheaper per mg at LabFirst; the 5 mg vial is the sensible first order while a lot is being qualified. No vial of BPC-157, from anyone, is pharmaceutical grade, because no USP monograph exists for it to meet, and no advisory committee vote has changed that.

What is BPC 157 studied for?

Published research on BPC 157 investigates the areas below, which is a different question from what BPC 157 will do for anyone, a claim about a living system that nothing on this site is sold for.

What it is. A man-made fifteen-amino-acid peptide, based on a protein found in stomach juice.

What the research looks at. It appears in animal and cell-culture research on tissue and blood-vessel biology. Almost everything published is animal or cell work.

How it is thought to work. Nobody has settled how it works. Cell and animal studies report effects on blood-vessel growth signals and on several growth-factor pathways, but no single receptor has been pinned down as its target and the studies do not agree on one model.

What is not established. No FDA-approved product contains BPC 157, and no USP or NF standard defines what an acceptable batch is. Human evidence is close to nonexistent. Any figure printed on a research vial is the supplier’s number, not an official one.

The full record, including the certificate for the lot in stock, is on the BPC 157 product page.

Common questions

Where can I buy BPC-157 peptide online?

From any supplier that can show, for the exact lot in the listing, a mass spectrum with the theoretical mass printed, an HPLC purity figure with its method and date, and a net content in milligrams. LabFirst sells BPC-157 in 5 mg and 10 mg vials from $49, ships within the United States, and publishes each lot's independent laboratory report at /coa/ with the laboratory's own lookup. Laboratory research use only.

How much does BPC-157 cost?

$49 to $59 a vial at LabFirst across 2 sizes, 5 mg and 10 mg, which is $9.80 to $5.90 per mg, read from the product page on November 4, 2026. Ten to nineteen vials of one size take 10% off, twenty or more take 15%. USPS Ground Advantage is free over $150 and a flat $15 below it. Compare other listings per mg only after confirming the certificate carries a net content figure.

Is BPC-157 the same as BPC 157, BPC157 and Bepecin?

Yes. The hyphen, the space and the run-together spelling are typographic variants of one fifteen-residue sequence, and Bepecin is an older name for the same material. What is not simply the same is BPC-157 arginate: the same peptide supplied as an arginine salt rather than an acetate, so its identity by mass is identical but its net peptide content per milligram of powder is not, and the certificate has to say which salt was weighed.

Which BPC-157 size should a laboratory order first?

The size that matches the work, then the per-mg column. The 10 mg vial is the cheaper per mg; the 5 mg vial costs least outright and is the sensible first order when a lot is being qualified before a larger buy. A first order of one vial, checked against its certificate on arrival, tells a laboratory more than any listing can, and the volume tier is there for the second order.

How do I check that a BPC-157 certificate is real?

Match the lot on the vial to the lot on the certificate, then verify the report on the testing laboratory's own site rather than the seller's. Confirm the theoretical mass printed matches the published value, 1418.704 Da monoisotopic for BPC-157, that the purity figure has a method and a date, and that a net content in milligrams is stated. A certificate that fails any one of those describes some other vial.
No approved medicine contains BPC-157. It left Category 2 of the 503A bulk substances list in April 2026 after its nominations were withdrawn, and on July 23, 2026 FDA's Pharmacy Compounding Advisory Committee reportedly voted 8 to 6 to recommend adding it to the list. That vote is advisory; as of November 4, 2026 FDA has not adopted it, and a change would need rulemaking first. Research-grade BPC-157 is sold for laboratory use only.

Why do BPC-157 prices vary so much between sellers?

Because the synthesis is cheap and the packaging, testing and marketing are not, so the powder is a small part of the price and everything else is discretionary. A seller that tests every lot at an outside laboratory, prints the lot on the vial and holds refrigerated stock pays for all three; a seller that ships a factory certificate written for some other lot pays for none of them. Compare per milligram, then ask which of those costs each price includes.
