Audit Notes & Receipts

First-hand vet (2026-09-30).
Progression Peptides, LLC publishes a public COA library at /coa-library/ with dated PDFs (Jun + Sep 2026) from named labs: Freedom Diagnostics (Franklin TN), Elevated Laboratories (La Grande OR), and BT Labs.
We opened two vendor-hosted PDFs: Freedom Tirzepatide 60mg (client Progression Peptides, lot 02065, accession 2606220419 / search Prog2606220419, HPLC-UV purity 99.91%, LC-MS identity confirmed, net content 63.01mg, received 06/22/2026 reported 06/24/2026) and Elevated Tirzepatide 60mg (lot 2065, task EL-2026-390, purity 99.18%, UHPLC-UV-PDA-QDA method, strength 60.08mg/vial, analyst Jesse McDonald, received 09/03/2026 tested 09/11/2026).
Library also lists Freedom/BT/Elevated COAs for retatrutide, MOTS-c, tesamorelin, BPC-157/TB-500 blends, CJC-1295/Ipamorelin, GHK-Cu, KLOW, SS-31.
Freedom is a lab we already treat as real from prior SomaChems / Rescue / Peptide Plugs audits.
Honest caveats keep this at published-unaudited rather than verified-real: the Freedom portal path used previously was unreachable this cycle (could not confirm "document found" live), panels omit endotoxin/sterility, Elevated Labs is not independently corroborated, the brand is ~7 months old, and DSIP (stocked) had no library COA at check. Graded B (69).
PepEvolution affiliate partner (disclosed): code rcl10, link https://progressionpeptides.com/shop/?coupon=rcl10, customer 10% off, 20% of order profit; dashboard live 2026-10-01.
Affiliate status does NOT lift COA status or grade.

Green bullets = directly verified data points. Amber bullets = caveats or open questions. Gray = disclosures.

Buyer Caution

Freedom Diagnostics public portal host used in prior PepEvolution audits (coas.freedomdiagnosticstesting.com) returned 404 this cycle, so claimed accessions were not re-verified live on the lab site; opened COAs omit endotoxin/sterility; secondary lab Elevated Laboratories (La Grande OR) has no independent public footprint; brand is young (domain registered 2026-02-20); DSIP product page is live but no DSIP COA was present on the library page at audit.
