● pepmg vendor score criteria-based · not a user review
82/100
82

Feel Good Peptides scores 82/100 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 (57 of 76). 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 (Horizon Analytical), 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 32 tracked listings. Its prices are machine-readable and it publishes a brief About page, and the domain is newer, online since Dec 2025, which pepmg counts as neutral rather than a mark against it. This rates what Feel Good 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.

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.

  • 19 of the 76 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 +14)
  • 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.

Certificates you can check at the lab

57 of 76 COA documents Feel Good Peptides publishes resolve to a report hosted by Horizon Analytical. 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.

Showing 40 of the 57 distinct reports. The full set, for every vendor, is at /api/coas.json.

● 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 Feel Good Peptides, 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.
