Crownwell Research scores 35/100 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: COA documents, no lab named. The biggest credibility signal pepmg weighs is how a vendor publishes lab tests: pepmg catalogued COA documents on its site, but none of them open at a testing lab's own site and none name a lab pepmg could resolve, so a buyer can read the documents without being able to confirm them at the source. 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 12 tracked listings. Its prices are machine-readable, and the domain is newer, online since Jan 2026, which pepmg counts as neutral rather than a mark against it. This rates what Crownwell 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.
- Room to improve Publishes COA documents — no testing lab attributed — 13 COA documents found, 0 with links to the testing lab's own site (some labs restrict automated access)
How we scored this
| COA transparency | | 30/87 | publishes COA documents — no testing lab attributed — 13 COA documents found, 0 with links to the testing lab's own site (some labs restrict automated access) |
| 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 | 1.11x the tracked median across 8 shared compound(s) |
| Catalog | 12 clean in-stock listing(s) tracked |
| Track record | active · new domain (online Jan 2026) — no age penalty |
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.
- 13 of the 13 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 +57)
- 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.

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 Crownwell Research, 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.
