Is Pulse Peptide Labs legit?
Pulse Peptide Labs scores 6.50 out of 10 (Fair, tied #46 of 100) as of November 2, 2026 and passes our testing gate: all 7 products we score carry a certificate, 7 confirmed with the issuing lab (a lab we grade A). Its strongest area is lab testing (7.9/10); its weakest is operating history (1.3/10), with about six months of records. We also record that most of its certificates were issued to another business.
On lab evidence, the heaviest-weighted factor, Pulse Peptide Labs has independently verified third-party COAs, with COA work on record from Freedom Diagnostics Testing. Its lowest price per milligram in our data is on NAD+ (see the table below).
How this score was calculated
Every point below follows the published tables in our methodology, with the policy wording we scored and a link to where we read it. Evidence last checked October 22, 2026. Lab credibility is worked product by product from the certificates on file.
Lab credibility7.9/10
Each carried product (lab supplies excluded) is scored from the certificate on file for it, on the published lab rubric: 3 for a published certificate, then points for the laboratory, the verification key, the tests on the certificate and its purity, held to 0 to 10. A certificate that is self-issued, names no laboratory, or comes from a laboratory whose independence is not established scores a flat 2.0; a product with no certificate, a certificate the laboratory’s own record fails, or a posted copy that differs materially from the laboratory’s copy scores 0. Calculated on , the day this page was built; the date each certificate was tested is shown on its row.

Editor’s notes
Pulse Peptide Labs, a Utah company, lists about forty products, but in October 2026 only seven could be ordered; the rest were marked coming soon. Every one of the seven has a Freedom Diagnostics certificate that we confirmed at the laboratory. The question a reader needs answered is whose certificates they are: six of the seven are issued to a supplier, Over Match Labs, rather than to Pulse, so they document the supplier's material, and two share one manufacturer lot. Only the retatrutide report is in Pulse's own name, and it is the best document in the set, covering identity, purity, net content, endotoxin and heavy metals. Product pages name Freedom Diagnostics as the laboratory. At our October 2026 audit, pricing sat above the market median on each of the products we list. Orders take one to three business days to process, ship with tracking through USPS, UPS or FedEx, and arrive in unbranded packaging with a generic return address. The domain was registered in April 2026, for three years rather than the single year most new vendors take.
