The PeRx standard
Peptide quality & potency testing.
Every peptide we ship is compounded at a state-licensed 503A pharmacy and verified by an independent lab for potency, sterility, endotoxins, and pH — before it ever reaches your door.
Four tests. Every lot.
What we test for, and why.
Potency
Confirms the active peptide is present at the labeled concentration on every batch — no overdose, no underdose.
Sterility
Tests for bacteria, fungi, and other microorganisms before any vial leaves the pharmacy.
Endotoxin
Screens for bacterial endotoxins that can cause adverse reactions even when sterility passes.
pH
Verifies the solution is in the correct range for comfortable subcutaneous administration.

What a Certificate of Analysis looks like.
This is a real certificate from a pharmacy in our network for a BPC-157 3 mg/mL lot tested in September 2026. We removed the pharmacy name, blacked out the approver and reviewer signatures, and marked the page as a sample. The lot, dates, and results are as issued. The certificate for the lot you receive is available on request.
- Lot number with manufacture, test, and expiration dates, so the report ties to one specific batch
- Identification by HPLC, where the sample peak matches the reference standard
- pH result against the 5.0 to 6.0 range set for comfortable subcutaneous injection
- Bacterial endotoxin (USP <85>) and sterility (USP <71>) results
- Reviewer and approver sign-off with dates
Why it matters
Most “research peptides” are never tested at all.
The grey-market peptide industry runs on imported powder, hopeful labels, and zero accountability. Independent audits routinely find products that are underdosed, contaminated, or contain the wrong molecule entirely.
- Compounded under USP <797> sterile standards
- Independent third-party potency verification
- Endotoxin tested per USP <85>
- Each vial lot-traceable from raw material to delivery
From raw material to your door
The full quality pipeline.
- 01
Pharmaceutical-grade raw materials
We source active peptides only from FDA-registered, GMP-compliant suppliers with full chain-of-custody documentation and certificates of analysis on every lot.
- 02
Compounded in licensed 503A pharmacies
Every prescription is compounded at a state-licensed 503A pharmacy in our network — operating under USP <797> sterile compounding standards.
- 03
Independent third-party testing
Every lot is tested by an independent laboratory — not by the pharmacy that made it. Potency, sterility, endotoxins, and pH are verified before release.
- 04
Cold-chain shipping
Vials ship FedEx Overnight from the pharmacy in temperature-controlled packaging — fully reconstituted, ready to use, tracked end-to-end.
Certificate of Analysis
Every batch is documented with a CoA from the third-party lab. Members can request the CoA for any lot they receive.

State-licensed and overseen by state boards of pharmacy. The same compounding framework used by hospitals and IVF clinics — applied to peptide therapy.
Cold-chain delivery
FedEx Overnight, temperature-controlled, signature on delivery. Your vial arrives fully reconstituted — the way it left the pharmacy.
