Where to buy BPC 157 TB-500 Blend: sizes, price per mg and how to verify the lot

What "bpc 157 tb-500 blend" names, and what it does not

This is a two-compound vial: BPC 157, the fifteen-residue peptide Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val at 1,419 Da, and TB-500, the N-acetylated seven-residue fragment Ac-LKKTETQ of thymosin beta-4 at 889 Da, freeze-dried together in equal labelled amounts. LabFirst lists it as 5 mg + 5 mg, 10 mg + 10 mg and 15 mg + 15 mg, and the label states the split rather than a single total, because a single total for a blend is a number nobody can check. Listings elsewhere call it the BPC-157 TB-500 blend, the BPC TB combo or, in a name that should tell you something about the seller, the "wolverine" blend.

Both components are cheap to synthesise, neither carries a cysteine or a methionine, and both are stable lyophilised powders, which makes this one of the easier blends to document. The difficulty is only that there are two of everything: two masses to confirm, two purities to report and two net contents that should add to the label. A certificate that reports one purity for the vial has measured neither compound in a way a buyer can use, and the ratio on the label becomes a claim with nothing behind it.

Each component has its own research record, all cell and animal work, and the papers cited at the foot of this page are for each individually; nothing has been published on the two together and nothing here describes any use. What a buyer can act on is that both are known molecules with known masses, and a laboratory can find both in one vial if it is asked to.

There is no single molecule to weigh. BPC 157 + TB-500 Blend is 2 peptides freeze-dried together in one vial: BPC 157 (C62H98N16O22, 1418.704 Da monoisotopic); TB-500 (C38H68N10O14, 888.492 Da monoisotopic). A mass spectrum of the vial therefore shows 2 separate masses, and a certificate that reports one number for the whole vial has not identified anything. Each component needs its own identity and its own share of the labelled milligrams.

In plain terms: Two man-made peptides freeze-dried together in one vial. No approved product and no official standard for either ingredient or for the blend. A vial holding two compounds has to be stored to suit the fussier one, and its paperwork should report each ingredient separately.

BPC 157 + TB-500 Blend for sale: sizes and price per mg

LabFirst lists BPC 157 + TB-500 Blend in 3 sizes (5mg + 5mg (10mg total), 10mg + 10mg (20mg total), 15mg + 15mg (30mg total)) from $60 to $135, priced per vial with the per-mg figure beside it so sizes can be compared without arithmetic. Per mg, the 10mg + 10mg (20mg total) vial is the cheapest today at $5.45 and the 5mg + 5mg (10mg total) the dearest at $6, which is the reverse of the usual shape; the table below is the arithmetic, and the per-mg column, not the vial price, is the one to compare.

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 the expensive half of this vial and TB-500 the cheap one, so a fair price sits between the two single-compound prices per milligram, and the blend's per-milligram figure should be read against both. The reason to buy the blend rather than two vials is that one vial, one freeze-drying run and one laboratory test cover two compounds; the reason not to is that the ratio is fixed at equal parts, which suits some work and not other work. LabFirst lists both single compounds beside the blend so the arithmetic can be done on one page with the cost per mg tool.

Where price tells you something on this blend is the certificate. A blend that comes with a two-line breakdown has been tested twice as thoroughly as a single compound, and that costs the seller more than a one-line certificate does. A blend priced well below the sum of its cheapest parts, with a one-line certificate, is not a bargain on two compounds; it is an unmeasured mixture at a mixture's price. The only discounts on this page are the volume tiers, per size, and the lot on the vial is whatever the certificate index says on the day.

The certificate a BPC 157 + TB-500 Blend lot must carry

Three tests answer three different questions, and a certificate of analysis for BPC 157 + TB-500 Blend is only complete when it carries all three for the exact lot on the vial. Identity for a blend means one confirmed mass per component: BPC 157 at 1418.704 Da, TB-500 at 888.492 Da. A single mass for the vial is not an identity result.

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 + TB-500 Blend actually in the vial, measured, against the size printed on the label.

A blend certificate needs two observed masses: within a fraction of a dalton of 1418.70 Da for BPC 157 and 888.49 Da for TB-500 (or their average masses, 1,419.5 and 889.0, if the laboratory reports those). The two are far enough apart that a deconvoluted spectrum shows them as separate peaks with no ambiguity, so there is no excuse for a certificate that prints one number. Two wrong answers are worth knowing: about 846 Da in place of 889 is TB-500 without its acetyl group, and about 1,322 Da in place of 1,419 is BPC 157 missing one proline. Either one means the vial is not what was sold.

Purity is per component from a single HPLC run, on which the two peptides separate cleanly (TB-500 first, BPC 157 later), and each should carry the method and the date. Net content is two lines in milligrams that add to the label: 5 mg + 5 mg means about 5 mg of each peptide, not 10 mg of powder that happens to contain both. Both peptides are usually supplied as acetate salts, and a laboratory that reports net peptide content rather than powder mass has accounted for the salt and the water. Ask for the two-line breakdown; without it, the equal split on the label is decoration.

Where to buy BPC 157 + TB-500 Blend: five checks before you order from anyone

Every seller of bpc 157 tb-500 blend 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 + TB-500 Blend" 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 + TB-500 Blend that means one mass per component.
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 + TB-500 Blend specifically mislead:

• "10 mg blend" with no split. Ten milligrams of a two-peptide mixture in an unstated ratio is a vial, not a product; the label should say how much of each, and the certificate should confirm it.
• One purity figure for the vial. Two peptides need two masses, two purities and two net contents; a single "99%" measured neither in a way that can be compared to anything.
• A certificate with a mass near 846 Da for the TB-500 line. That is the fragment without its acetyl group, a different compound, and it is the most common substitution in this blend.
• A blend priced below the cheapest single-compound BPC 157 per milligram. BPC 157 is the costly half; a price that ignores that is a price for something else.

How to verify a LabFirst BPC 157 + TB-500 Blend lot

The BPC 157 + TB-500 Blend sizes in stock today carry lots LF-2608-06 and PO-1001-BB20. Lot LF-2608-06 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 + TB-500 Blend

Both components are robust as dry powders: no disulfide to scramble, no methionine or tryptophan to oxidise. Sealed and refrigerated at 2 to 8 C out of light, the cake stays as it left the laboratory for the shelf period on the certificate. The one chemical thing to know is the glutamine at the C-terminus of TB-500, which can deamidate slowly in solution and shift retention time by a peak, so a prepared solution is dated, kept cold and used inside the laboratory's own stability record. The practical enemy of the sealed cake is water: open a vial once, for its purpose, and never re-seal one for storage, because a cake that has taken on moisture no longer weighs what either line of the label says.

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 + TB-500 Blend 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

No approved medicine contains BPC 157 or TB-500, and no monograph could apply to a blend with no fixed identity. Both components were placed in Category 2 of the FDA's interim 503A bulk substances list in September 2023, the category for substances the agency identified as raising significant safety risks, which bars licensed pharmacies from compounding with them; BPC 157's entry has since been taken off Category 2 for advisory committee review, which is not the same as being permitted. Those listings concern pharmacies and drug products, not laboratory material, and are quoted because no component of this vial can be called pharmaceutical grade by anyone.

FOR LABORATORY AND IN-VITRO RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION. LabFirst sells BPC 157 + TB-500 Blend 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.
