Prime Peptides scores 89/100 in pepmg's criteria-based Vendor Score, which rates only what a vendor publishes about lab testing and about itself, not its products and not its prices. What we observed: most COAs openable at the testing lab (37 of 43). The biggest credibility signal pepmg weighs is how a vendor publishes lab tests: the documents counted above open at the testing lab's own site (Freedom Diagnostics, Horizon Analytical, Janoshik), where the lab itself can confirm the result, and the rest are hosted by the vendor, where it cannot. Neither price nor catalog size affects this score, but for context it prices around the tracked median across the compounds it shares with other tracked vendors, over 21 tracked listings. Its prices are machine-readable, and the domain has been online about 2.5 years. This rates what Prime Peptides publishes about lab testing and about itself, not the purity or authenticity of any vial, which pepmg can't verify, so read the COAs yourself. Research use only.
- Strength Third-party COAs, results hosted at the lab (Janoshik, Freedom Diagnostics, Vanguard Sciences, Bioviridian, Vanguard Laboratory, Horizon Analytical) — strongest public signal — 43 COA documents found, 37 of them openable at the testing lab's own site
How we scored this
| COA transparency | | 84/87 | third-party COAs, results hosted at the lab (Janoshik, Freedom Diagnostics, Vanguard Sciences, Bioviridian, Vanguard Laboratory, Horizon Analytical) — strongest public signal — 43 COA documents found, 37 of them openable at the testing lab's own site |
| About / who they are | | 0/8 | no About/founder page found |
| Public price data | | 5/5 | publishes machine-readable public prices |
Stated, but NOT scored. These describe the vendor; they earn no points either way.
| Price vs market | 1.10x the tracked median across 15 shared compound(s) |
| Catalog | 21 clean in-stock listing(s) tracked |
| Track record | active · domain online ~2.5y (since 2024) |
What would raise this score. Published behaviour only. How a vendor runs its business is its own call, and none of this affects the $/mg ranking.
- 6 of the 43 published COA documents open on the vendor's own site rather than at the testing lab. Linking the lab's own copy on those pages would let a buyer confirm the result at the source. (up to +3)
- An About or founder page saying who is behind the business. (up to +8)
Computed from what this vendor publishes about lab testing and itself. Price and catalog size are shown above as facts and are deliberately NOT scored — $/mg is the ranking, and it is affiliate-blind. No opinions, no testimonials.
Are you the vendor? If you have changed something we score here, published something we did not find, or think we got it wrong, reach out or email hello@pepmg.com and we will re-check. Vendor corrections have already changed ratings on this site.
Certificates you can check at the lab
37 of 43 COA documents Prime Peptides publishes resolve to a report hosted by Freedom Diagnostics or Horizon Analytical or Janoshik. The lab's copy is linked first because it is the one the vendor cannot edit. pepmg has not tested anything — the lab's own copy is linked; we did not read the certificate or vouch for it, and some labs bot-block our crawler, so a link may be one a person can open and we could not. A certificate covers the batch it was issued for, which may not be the vial you receive.

We don't host reviews — an unverifiable review box is a magnet for bots and paid posts, and we won't pretend otherwise. Instead, here's where you can read what real buyers say about Prime Peptides, on sites we don't control:
These are independent, unmoderated sources — we link them, we don't vouch for them, and a "profile" or "search" link may turn up little or nothing. pepmg's job is the part we can stand behind: prices captured first-party with a timestamp, ranked purely by $/mg, plus the objective Vendor Score above. Vetting a source you're about to buy from still matters, and that call is ultimately yours — we've made it as informed as we honestly can.
Vendor links are temporarily offline while we review our referral and linking policies. Listings remain for price transparency.
