VERIFIEDpurity.
The human body is a system of peptides — protein chains that signal, repair, regulate. Every compound we sell is batch-tested, COA-published, sourced openly.No theatre.
Growth.
Tirzepatide, retatrutide, and adjacent GH-axis agonists. The compounds the catalog leans into.
Class lead
Tirzepatide
GLP-1 / GIP dual agonist · 10mg lyophilized
Metabolic.

Year to date · 2026
Average verified HPLC purity, across every batch we've sold this year.
Each number on the ledger checks out.
Every batch is sent for independent HPLC analysis. Results are published per product page the moment they land — no rounding, no marketing pass. The average above is the arithmetic mean across our entire active catalog, recalculated as new batches verify.
Position
Most peptide stores treat transparency as marketing.
We treat it as the product.
01
Real COAs
Every batch tested by an independent lab. PDFs downloadable on every product page.
02
Reported purity
HPLC percentages published per batch, to the decimal. Not adjectives, not '99%+'.
03
Disclosed sourcing
Country of origin and manufacturing standard on every compound. Verified or not claimed.
