Where to buy BPC 157 Peptide: sizes, price per mg and how to verify the lot

What "bpc 157 peptide" names, and what it does not

BPC 157 is a fifteen-residue synthetic peptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. The name is an abbreviation of "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 in listings as BPC-157, BPC157, bpc 157 peptide, pentadecapeptide BPC 157 and, occasionally, under the older name Bepecin. All of those are one sequence. What is not the same molecule is "BPC 157 arginate", a salt form some sellers market as a distinct product; it is the same peptide paired with arginine as the counter-ion, and a certificate for it must still confirm the peptide by mass.

It matters that this is a linear peptide with no disulfide bridge and no unusual residues. That makes it cheap to make by solid-phase synthesis, which is why it is one of the most listed research peptides on the internet and why the spread in quality between sellers is so wide. A fifteen-residue synthesis with three consecutive prolines produces deletion sequences (a chain missing one proline) that run close to the main peak on HPLC and are only caught by a laboratory that reports the mass of the main peak, not just its area. Sellers who quote purity from a single unlabelled chromatogram are, whether they know it or not, quoting the wrong number.

Almost everything published on BPC 157 is animal or cell-culture work, and the mechanism is not settled; the papers cited at the foot of this page describe effects on blood-vessel signalling in cells and rodents. None of that describes anything in a person, and this page does not either. What a buyer can act on is the chemistry: a known sequence, a known mass, and a laboratory that can confirm both.

The reference point for identity is public. PubChem lists BPC-157 as CID 9941957 with molecular formula C62H98N16O22, an average molecular weight of 1419.5 Da and a monoisotopic mass of 1418.704 Da. Those are the numbers a mass spectrometer is checked against, and the number a certificate must print beside the observed mass.

In plain terms: A man-made fifteen-amino-acid peptide, based on a protein found in stomach juice. 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.

BPC 157 for sale: sizes and price per mg

LabFirst lists BPC 157 in 2 sizes (5mg, 10mg) from $55 to $60, priced per vial with the per-mg figure beside it so sizes can be compared without arithmetic. Per mg, the 10mg vial is the cheapest at $6 and the 5mg the dearest at $11, which is the usual shape: the vial, stopper, seal, fill and laboratory run cost the same whatever mass goes in.

The volume tiers are per size, not per basket: ten vials of one size take 10% off that line and twenty take 15%, and mixed sizes do not combine. Shipping is a flat $15 on orders under $200 and free from $200, within the United States only, with same-day dispatch on 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.

BPC 157 is one of the cheapest peptides in the catalogue to synthesise, and the price of a vial 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. That is why the 10 mg vial costs so little more than the 5 mg vial and why the per-milligram figure falls so steeply between them. 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.

The other price signal to read is the direction of a discount. A seller offering 40% off BPC 157 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. LabFirst's volume tiers are the only discounts on this page, they are the same every month, and the lot on the vial is whatever the certificate index says it is on the day.

The certificate a BPC 157 lot must carry

Three tests answer three different questions, and a certificate of analysis for BPC 157 is only complete when it carries all three for the exact lot on the vial. Identity is settled by mass spectrometry, and the number to look for on a BPC 157 certificate is 1418.704 Da monoisotopic (or 1419.5 Da average, if the laboratory reports the deconvoluted average mass). The observed mass should sit within the instrument's stated tolerance of that figure, and the certificate should print both the theoretical and the observed value, not just a tick.

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, and a certificate that carries every test but for a different lot number than the vial is the most common failure of all and the easiest to catch. Net content is the third test and the one most often missing: the milligrams of BPC 157 actually in the vial, measured, against the size printed on the label.

For BPC 157 the first thing to read on a certificate is the observed mass. The peptide has a monoisotopic mass of 1418.704 Da, so an electrospray spectrum shows the doubly charged ion near m/z 710.4 and the triply charged near m/z 473.9; a laboratory that deconvolutes the spectrum will print a value within a fraction of a dalton of 1418.7, or 1419.5 if it reports the average mass. A certificate that prints "identity: conforms" with no spectrum and no number has not shown you identity. A certificate that prints a mass a proline short (about 1321.7 Da) has identified a deletion product, and a chromatogram that shows a shoulder on the main peak is often that product at a few percent.

The second thing to read is the counter-ion. BPC 157 is supplied as the acetate or, less often, the trifluoroacetate left over from purification. Trifluoroacetate is not a purity problem for the peptide itself, but it changes the net content: a vial labelled 5 mg that is 5 mg of peptide-plus-TFA contains less peptide than one that is 5 mg of acetate salt, and a certificate that reports net peptide content by amino acid analysis or by quantitative HPLC against a standard settles the question. Ask for that line specifically. Sellers who cannot say which salt they ship are usually reading a certificate that a factory wrote for a different lot.

Where to buy BPC 157: five checks before you order from anyone

Every seller of bpc 157 peptide 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. LabFirst lots are tested by Freedom Diagnostics and looked up by accession number; anything that can only be verified on the seller's own page 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 either 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. A figure that reads "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. If the certificate has no net content line, the purity figure describes the powder, not the vial, and the price per mg you calculated is fiction.

How listings for BPC 157 specifically mislead:

• The words "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 counter-ion, and the certificate must still show the peptide mass and a net content that accounts for the salt.
• A certificate that shows 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.

How to verify a LabFirst BPC 157 lot

The BPC 157 sizes in stock today carry lots LF-2608-05 and PO-1001-BC10. Lot LF-2608-05 is at Freedom Diagnostics on accession FD-2026-05716 for identity, purity and net content. Until the 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, on the page, at /coa/, and inside the receipt and packing slip for every order of that lot.

Verification runs through the laboratory, not through us. Open the certificate index, find the lot, and use the accession number on the Freedom Diagnostics lookup page; the report you see there is the laboratory's copy, not ours. Each lot also carries a Finnrick verify link, and every receipt and packing slip states that a customer may submit a sealed vial to Finnrick's free testing programme with the order as proof of purchase, so the brand's public record is built from vials we did not choose.

The product page reads the live stock feed on load (stock, lot and certificate state for every size), so what you see when you order is what ships. 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.

Storage and shipping for BPC 157

Sealed and lyophilised, 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 oxidise, which is more than can be said for most of the catalogue. The practical risk is water. A vial opened and re-closed at room humidity pulls moisture into the cake, which then clumps, discolours and no longer weighs what the label says; open a vial once, for its purpose, and do not re-seal it for storage. Once in solution the record belongs to the laboratory that made it: solvent, concentration, date, temperature. Nothing on a label can stand in for that record.

Orders ship within the United States, flat $15 under $200 and free above it, same day when placed before 12 PM Pacific on a business day, and the shipping page states the cutoff, the carriers and what is and is not promised.

The record a laboratory keeps on arrival is what makes the certificate usable later, and it is short:

• 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 BPC 157 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.

Regulatory status, and what this page is not

BPC 157 is a man-made fifteen-amino-acid peptide with a research record built on animal and cell studies. No FDA-approved product contains it, and there is no official USP/NF standard for it. That second point matters if you are judging suppliers: with no official standard, there is no rulebook saying what an acceptable batch of this substance even is.

The FDA put BPC 157 in Category 2 of its 503A bulk drug substances list, the group of substances that may carry significant safety risks, in its update of 29 September 2023. In April 2026 the FDA took it out of Category 2 after the nomination behind it was withdrawn. Coming off Category 2 is not the same as going onto Category 1: it was not added to the list of substances pharmacies may compound, and it is still neither FDA-approved nor covered by a USP/NF standard. BPC-157-related substances went back before the Pharmacy Compounding Advisory Committee on 23 July 2026.

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. Nothing on this page or on the product page describes preparing or administering anything.

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.
