Peptide Vendor COA Lookup

The one question that matters before you buy: does this vendor publish real, independent lab tests? We track which research-peptide vendors post genuine accredited-lab COAs (Janoshik, Colmaric, MZ Biolabs) — and which rely on recycled, failed, or missing certificates.

How this list is ordered. Vendors are ranked by their independent PepScore vendor grade and COA status — never by whether they pay us. Some vendors are affiliate partners(clearly badged); an affiliate vendor never outranks a non-affiliate one.Revenue is disclosed; ranking is provable.
What the COA statuses mean
VerifiedIndependent accredited-lab (Janoshik / Colmaric / MZ Biolabs), batch-matched COAs are publicly posted and corroborated.
Publishes COAsThe vendor publishes COAs, but PepEvolution has not yet independently authenticated or batch-matched them.
Recycled COAsCOAs are stale, generic, or not lot-matched to the product you would actually receive.
Red flagDocumented evidence of fabricated, mismatched, or failed COAs. Buyer caution.
No COAsThe vendor publishes no certificates of analysis.
UnknownPepEvolution has not yet verified this vendor’s COA practices.

⚠ Regulatory Watch / Buyer Caution

Modern AminosRed flag

Independent COAs reportedly showed failed BPC-157 potency/purity; pricing well below market for rare compounds.

Paradigm PeptidesUnknown

Shared ownership with Amino Asylum, whose founders pleaded guilty to federal drug charges.

The Vendor Graveyard — Shut Down / Enforcement Action

No longer operating — do not purchase. Kept on record because the reason they closed is the reason COA verification matters.

Amino AsylumDefunct

FDA raid June 2025 (Memphis, TN). Founders Matthew Kawa and Jennifer Stechkober pleaded guilty to federal charges December 2025 (products labeled as SARMs that contained testosterone; selling unapproved drugs). Sentencing scheduled July 30, 2026. Same principals operated Paradigm Peptides.

Peptide SciencesDefunct

Voluntarily shut down March 6, 2026 amid the FDA enforcement wave. Was the largest US gray-market research-peptide vendor (~$7.4M/mo online sales, Dec 2025).

Science.bioDefunct

Shut down January 2026 during the FDA enforcement wave.

Accuracy is the brand. A wrong COA flag is worse than “unknown.” Every status here is either corroborated from the vendor’s own published COAs, the public Janoshik database, or independent test reports — or it is explicitly marked not yet verified. We never invent a status.See full methodology →
