CURATED VENDOR PROFILE
Instant Peptides
A Tempe, Arizona storefront that leads with same-day shipping and an unusually data-rich public testing layer, worth tracking as a transparency-forward US vendor.
Same formula for every vendor: verifiable testing evidence forms the backbone; third-party reviews adjust it within a bounded range. How scoring works →

Publishes a structured, per-batch COA archive covering the whole catalog — quantitative purity, average net content (fill accuracy), vials tested, and an endotoxin / heavy-metals / sterility safety panel per batch, all openly inspectable. That is a stronger public-evidence pattern than generic "COA available" language, though the testing is vendor-published rather than run through an outside verification portal.
Readers who want openly published, quantitative per-batch testing data (purity, fill accuracy, safety panel) rather than scattered COA links or generic quality claims.
The testing archive is vendor-published (self-reported), not verifiable against an outside lab portal. Note also that its GLP products are branded — GLP-3 RT is retatrutide, GLP-2 TRZ is tirzepatide, GLP-1 SM is semaglutide.
Public COA archive with per-batch purity and safety panel
Instant Peptides exposes a public lab-tests archive with per-batch, per-concentration certificates: quantitative HPLC purity, average net content, vials-tested counts, and endotoxin / heavy-metals / sterility results. The documents are vendor-published — no named third-party lab or externally verifiable report code — so it sits in the public-docs lane rather than provider-verified.
