TB-500 for Sale and BPC-157: Separate Vials or the Wolverine Blend, Price and COA
Research use only. Peptides supplied by Peptryn are sold strictly for in vitro and preclinical laboratory research. They are not approved by the FDA for human or veterinary use, and nothing here is medical advice, a dosing recommendation, or an instruction for self-administration. This page explains what Peptryn’s BPC-157 and TB-500 listings include and how to check any vial of either.
Quick answer: Peptryn sells BPC-157 and TB-500 as separate 10 mg lyophilized research vials: BPC-157 for $79.99 ($8.00 per mg) and TB-500 for $89.99 ($9.00 per mg). Both come from lot 2026-08-05 and were tested by MZ Biolabs, which reports 99.50% HPLC purity for BPC-157 and 99.84% for TB-500, with negative endotoxin results. Buying the two separately costs $169.98, which is $30.02 less than the $200 Wolverine blend that holds 10 mg of each. Neither compound is an approved drug, and Peptryn sells both only for laboratory research to buyers who are 21 or older.

Key takeaways
- BPC-157 10 mg lists at $79.99 and TB-500 10 mg at $89.99. Quantity pricing takes 3%, 5% or 10% off each.
- Both certificates read negative for endotoxin, and each purity and identity record sits on MZ Biolabs’ own site.
- In our September data report the lab measured 12.16 mg of BPC-157 (+21.6%) and 12.80 mg of thymosin beta-4 in TB-500 (+28.0%) against 10 mg labels. Each is one lot from one lab.
- The name TB-500 is used for two different molecules. Peptryn’s listing is full-length thymosin beta-4 acetate at 4,963.44 Da, so check the molecular weight on any certificate.

The BPC-157 product page and TB-500 product page list the full specifications. Peptryn does not give dosing or use guidance for either compound, because no dose has been established for either.
What each compound is
BPC-157 is a synthetic 15-amino-acid peptide, a fragment of a protein found in human gastric juice. TB-500 is a name that covers two different molecules. Anti-doping literature uses it for a short acetylated fragment of thymosin beta-4, and some suppliers use it for the full 43-amino-acid protein. Peptryn’s listing is the full-length form, thymosin beta-4 acetate, at 4,963.44 Da. Our TB-500 guide explains the naming.
That makes the molecular weight on a certificate worth checking. A report that lists a mass far from 4,963 Da, or from 1,420 Da for BPC-157, is describing something else.
Separate vials or the Wolverine blend
| Two separate vials | Wolverine blend | |
|---|---|---|
| Price | $169.98 ($79.99 plus $89.99) | $200.00 |
| Contents | 10 mg BPC-157 and 10 mg TB-500 | 10 mg BPC-157 and 10 mg TB-500 in one 20 mg vial |
| Certificates | Two, one per compound | One, for the blend (lot 2026-08-05, 99.13% HPLC purity) |
| Measured amounts | BPC-157 12.16 mg, thymosin beta-4 12.80 mg | BPC-157 11.64 mg, thymosin beta-4 13.56 mg |
The separate route costs $30.02 less for the same labeled amounts. The blend gives you one vial and one certificate instead of two. Measured amounts in the blend came in at +16.4% for BPC-157 and +35.6% for thymosin beta-4, from one lot and one lab. “Wolverine” is a nickname, not a standard formulation, so the split can differ between sellers. Our Wolverine buying page covers that listing.
BPC-157 and TB-500 price: what to compare
At the listed prices, BPC-157 costs $8.00 per mg and TB-500 $9.00 per mg. Price per mg compares two sellers only when the products match. Line up these before you compare:
- Size and form. Sellers list 5 mg and 10 mg vials. Peptryn lists 10 mg vials only.
- Which TB-500 it is. The full protein and the short fragment are different molecules with very different weights.
- Lot and lab. A price with no lot-matched report gives you a number and no verification.
- What the report covers. Purity, identity, endotoxin and quantity are separate results.
What the certificates show and leave out
| Question | What the certificates show |
|---|---|
| Method | HPLC-UV-MS on both |
| Purity | BPC-157 99.50%, TB-500 99.84% |
| Endotoxin | Negative on both |
| Where the records sit | The purity and identity records are on MZ Biolabs’ own site and linked by a QR code on each certificate. The endotoxin reports are PDFs shown on the certificate pages |
| Quantity per vial | The lab reports on the certificate pages print a measured quantity per vial |
Our September 2026 data report read the lab’s reports for these lots and listed the measured quantities: 12.16 mg of BPC-157 against a 10 mg label (+21.6%) and 12.80 mg of thymosin beta-4 against 10 mg (+28.0%). Each result comes from one lot, from one laboratory, without a stated assay uncertainty. The report lists open questions, including whether a quantity figure is net peptide content or the gross contents of the vial.
Five checks for any BPC-157 or TB-500 vial
- Does the lot match? Compare the lot on your vial with the lot on the report, and check that the analysis date fits the lot date.
- Is the report on the lab’s own site? A link or QR code to the lab’s record beats a PDF that lives only on the seller’s server. Our third-party tested peptides guide sorts these claims into five levels.
- Does the mass match the compound? About 1,419.5 Da for BPC-157, and about 4,963.4 Da for full-length thymosin beta-4.
- Which tests are listed? Identity, purity, endotoxin and quantity are different tests. Each one missing is a gap, and our certificate guide shows how to read them.
- How does the seller describe use? A research listing promises no healing, recovery or performance results and gives no dosing schedule. The research on both compounds comes mainly from animals and cells, with at most a few small human studies, and none of it settles those claims. See are peptides legal? for background.
Why search results for these two look so mixed
On October 13, 2026, the first page for “bpc-157 for sale” held pharmacies, large retailers and clinic programs, and the first page for “tb-500 for sale” held telehealth programs, pharmacies and a few research shops. These are different products with different rules.
Peptryn’s listings are laboratory research materials. They are not clinic programs, supplements or drugs, and Peptryn does not offer them for human use.
Common questions
Where can I buy BPC-157 and TB-500 for research?
Peptryn sells both on its BPC-157 and TB-500 product pages, only for laboratory research, to buyers who are 21 or older and who confirm qualified research use.
How much do BPC-157 and TB-500 cost?
Peptryn lists BPC-157 10 mg at $79.99 ($8.00 per mg) and TB-500 10 mg at $89.99 ($9.00 per mg). Quantity pricing takes 3% off at 3 to 4 units, 5% at 5 to 9 and 10% at 10 or more. Prices change, so check the product pages.
Should I buy them separately or as the Wolverine blend?
The separate vials cost $169.98 against $200 for the blend, for the same labeled amounts. The blend means one vial and one certificate instead of two. Compare the certificates for what each reports.
Are Peptryn’s BPC-157 and TB-500 third-party tested?
Yes. Lot 2026-08-05 of each was tested by MZ Biolabs: 99.50% HPLC purity for BPC-157 and 99.84% for TB-500, both with negative endotoxin results. The purity and identity records are on the lab’s own site, and Peptryn is the client that ordered the tests.
Is TB-500 the same as thymosin beta-4?
Sometimes. Anti-doping literature uses TB-500 for a short fragment, and some suppliers use it for the full 43-amino-acid protein. Peptryn’s listing is full-length thymosin beta-4 acetate at 4,963.44 Da.
Do the certificates show the quantity per vial?
Yes. The lab reports on the certificate pages print a measured quantity per vial. Our September data report lists 12.16 mg for BPC-157 and 12.80 mg for thymosin beta-4 against 10 mg labels, each from one lot at one lab.
Is BPC-157 FDA approved?
No. In July 2026 an FDA advisory committee voted 8 to 6 to recommend BPC-157, TB-500 and KPV for a compounding list. That vote is advice, not approval.
Are BPC-157 and TB-500 banned in sport?
Yes. BPC-157 is on the World Anti-Doping Agency’s prohibited list, and WADA prohibits thymosin beta-4 and its derivatives, with TB-500 named as an example.
