GenPeptide's COA lookup and our COA library provide 111 complete reports across 33 compounds: 78 from Freedom Diagnostics, 18 from Chromate, 11 from Kovera Labs and four from Janoshik. Dated January 3–September 21, 2026, the archive includes 46 reports for current offers and 65 historical reports. All 111 carry COA verified status, with 107 matched to specific laboratory records and four verified from their GenPeptide client or vial details.
Every one of the 111 reports carries an identity result, a numerical purity and a measured content. Purity runs 98.05%–99.968%, and 99 of the 104 single-value results are 99% or higher. Sixteen reports add endotoxin and 16 add heavy metals (arsenic, cadmium, lead and mercury), and six add microbial testing: Janoshik TAMC/TYMC counts on GLP-3R 6 mg, GLP-3R 10 mg and SS-31 30 mg, and PCR screening on three September 9 Freedom reports (GLP-2T 60 mg, CJC-1295 + Ipamorelin and KLOW). PCR screening is separate from culture-based sterility. Freedom, Chromate and Kovera print endotoxin as a laboratory Pass without a concentration; Janoshik prints numbers: 6.881 EU/vial for GLP-3R 10 mg, 1.287 EU/vial for SS-31 and under 1 EU/vial for GLP-3R 6 mg. Heavy metals are not detected or pass on every report that includes them.
Measured content is reported separately from purity and usually exceeds the label. Of 90 single-compound reports that print one measured amount against a nominal strength, 81 measured above it, with a median of 116% of nominal; the highest is a March 6 GLP-3R 6 mg vial at 9.02 mg. Nine measured below, and five of those are current: Thymosin Alpha-1 at 10.56 mg (the report's table prints 13 mg while its photographed vial says 10 mg, so it receives no exact listing control), NAD+ at 481.97 mg of 500 mg, 5-Amino-1MQ at 47.87 mg of 50 mg, TB-500 at 9.66 mg of 10 mg and GHK-Cu at 48.98 mg of 50 mg. The three-vial Janoshik reports show the spread: SS-31 30 mg measured 28.15–29.13 mg, GLP-3R 6 mg 7.27–7.60 mg and GLP-3R 10 mg 11.53–11.95 mg. A March CJC-1295 + Ipamorelin report measured Ipamorelin at 4.41 mg against 5 mg with 98.05% purity, the lowest purity in the archive.
Four Freedom Diagnostics reports had no online lookup result on October 15, 2026: NAD+ 500 mg (accession 2605060251, May 8), N-Acetyl Semax Amidate 10 mg (2603060020, March 6), N-Acetyl Selank Amidate 10 mg (2603060021, March 6) and GLOW Protocol 70 mg (2606190491, June 23). The first three name GenPeptide as the client. The GLOW file shares its accession with a laboratory-matched GenPeptide report and shows a GenPeptide-labelled vial with lot GPGLO70061726. These four carry COA verified status based on those client or vial details, separately from the 107 online issuer matches. They do not verify product listings; each product has another laboratory-matched report in the library.
The October 15, 2026 catalog lists 53 offers across 34 compounds, 52 in stock (Tesamorelin 10 mg was out of stock). Examples: BPC-157 10 mg $35, GLP-3R 10 mg $55 or five 10 mg vials for $220, GLP-2T 30 mg $90 and GLP-1S 5 mg $35. Certificate controls require the same compound, nominal strength, unit and formulation. Fifty-one of the 53 offers carry one, built from 41 exact product keys. Five-vial kits (GLP-3R 6, 10, 12, 24 and 48 mg per vial; GLP-2T 10, 20, 30 and 60 mg per vial) match by per-vial strength, and pack mass never selects a certificate. Two blend offers have none: Cartalax + TB-500 + BPC-157 (30 mg) is outside the supported-compound scope, and the retained Semax + Selank report does not establish the listed N-acetyl amidate formulation. A Build-A-Kit page offers 20% off five-vial mini kits.
Trustpilot showed 4.4/5 from 30 reviews on October 15, 2026: 24 five-star, three four-star, two three-star and one one-star. Twenty-one of the 27 readable entries carry Trustpilot's Verified label.
