● pepmg vendor score criteria-based · not a user review
62/100
62

S1 Research scores 62/100 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: some COAs openable at the testing lab (42 of 102). 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, 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 below the tracked median across the compounds it shares with other tracked vendors, over 27 tracked listings. Its prices are machine-readable and it publishes a brief About page, and the domain has been online about 1.3 years. This rates what S1 Research 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.

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.

  • 60 of the 102 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 +34)
  • An About or founder page saying who is behind the business. (up to +4)

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

42 of 102 COA documents S1 Research publishes resolve to a report hosted by Freedom Diagnostics 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.

● INDEPENDENT REVIEWSoff-site · not ours

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 S1 Research, on sites we don't control:

r/Peptides discussion ↗ · search Trustpilot profile ↗ · search

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.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
