Peptide Vendor Directory: Research Peptide Companies, Scored and Reviewed
This directory covers the research peptide companies Project Biohacking has reviewed. Each one is scored out of 100 on four things: lab testing documentation, ownership, how it does business, and its track record.
Use the listings below to compare companies, then open a review to see the evidence behind a score. Each listing also shows the Project Biohacking code for that company and the month we last checked it.
Project Biohacking is paid a commission on orders placed through these links. The commission does not change a score.
Further down is a list of peptide companies readers ask about that we have not reviewed.
Peptide Sciences shut down on March 6, 2026 and is not taking orders or giving refunds. The companies in this directory are taking orders, and each one has been reviewed.
Affiliate Disclosure: Project Biohacking may earn a commission on purchases made through links on this page, at no extra cost to you.
How Project Biohacking Scores Peptide Companies
Each supplier carries a score out of 100: half the weight sits on analytical documentation, 20 points each on ownership and on commercial and operational factors, and 10 on community track record.
The score measures what a company documents and how it operates. A score is not a statement that a compound is safe, that it works, or that it is fit for use in people or animals.
All products listed are research chemicals intended for laboratory and in vitro use only. Nothing on this page is medical, legal, or financial advice. Consult a qualified professional before making health-related decisions.
Note: Project Biohacking provides affiliate links for informational purposes only. These partner offers are not medical advice. The compounds listed are sold by their vendors for research purposes only. Peptides intended for human use are available by prescription through a licensed clinician.

Peptide Vendor Directory FAQ
Which peptide companies has Project Biohacking reviewed?
Eight so far: Peptidology, Biolongevity Labs, Ascension Peptides, BioEdge Research Labs, Limitless Biotech, Ameano Peptides, Apollo Peptide Sciences and CanLab International. Each listing above links to the full review.
How does Project Biohacking score a peptide company?
The score runs to 100 points. Half are for lab testing documents, 20 for ownership, 20 for how the company sells and operates, and 10 for its track record in the community. The stars on each listing come from that score.
Does Project Biohacking earn money from the companies in this directory?
Yes. Project Biohacking is paid a commission on orders placed through the links on this page. That payment has no say in how a company is scored.
Are the codes on this page still active?
Yes. Every code on this page went through a live checkout at its vendor on November 1, 2026, and all eight are rechecked monthly. A code that stops working comes off the page.
What are PROBIO, PROBIO15 and PROBIO20?
They are the three Project Biohacking codes used across the companies in this directory. PROBIO15 takes 15 percent off, PROBIO20 takes 20 percent off, and PROBIO is the base code used where a company runs a different rate. Each company page states which code applies to it, what discount it carries, and what it applies to.
Is Peptide Sciences still in business?
No. Peptide Sciences voluntarily shut down on March 6, 2026. The website is dark and the company is not accepting orders, fulfilling pending shipments, or responding to customer inquiries. The closure followed a period of intensifying FDA enforcement and pharmaceutical litigation against research peptide vendors. There is no indication the company plans to reopen.
Research compounds discussed here are for laboratory research only, not for human or veterinary use, and nothing on this page is medical advice.
