About PPI
We're the wholesale supply chain behind the next wave of independent peptide brands.
PPI exists because the research-peptide market is split between overpriced retail storefronts and unverifiable bulk suppliers. We sit in the middle: true wholesale 10-vial kit pricing for resellers and bulk personal-use researchers, with HPLC chromatograms, mass-spec identity confirmation, and lot-traceable COAs shipped with every order. No minimums beyond a single kit, no exceptions on paperwork.
Verified purity
Every batch tested at ≥99% by independent HPLC labs.
Mass-spec identity
Identity confirmed by molecular weight — never assumed.
Lot traceability
COA archived per lot. Available on request, forever.
Free worldwide delivery
Free tracked shipping on every order, arriving in approximately 10 business days.
Our standards
PPI works exclusively with manufacturers whose facilities operate under quality-management systems compatible with cGMP guidelines. Every lot we receive is independently re-tested before being listed. We don't release inventory until purity, identity, and endotoxin pass.
We choose to remain independent of our manufacturing partners — and we don't disclose them — so that our COA program remains a true third-party verification, not a marketing exercise.
