Sourcing & Lab Testing

Pharmaceutical-grade peptides. Full chain of custody.

Every batch PeptideVault ships is synthesized in the United States, independently lab-tested before release, and tracked from compounding to your door. Here is exactly how that works — and the paperwork that proves it.

Where the peptide comes from.

US-Manufactured

Synthesis takes place in American cGMP facilities. No overseas brokers, no relabeled imports — every amino-acid chain starts inside a US-based compounding lab.

503A Pharmacy Network

Peptides are dispensed patient-specifically through licensed Section 503A compounding pharmacies, under a physician-signed prescription, every time.

Physician-Supervised

A licensed physician signs off on every prescription. The protocol is matched to your goals and labs — not a templated supply order.

What happens between synthesis and release.

01

Synthesis

The amino-acid sequence is assembled in a US cGMP lab under controlled conditions, with full lot tracking from raw materials onward.

02

Sample Pull

A retention sample is pulled from every production batch, sealed, and sent to an independent third-party laboratory — never in-house.

03

Independent HPLC / MS

The third-party lab runs high-performance liquid chromatography and mass spectrometry to verify identity, purity, and the absence of residual solvents.

04

COA Match

Returned results are checked against release specifications — purity ≥ 98%, endotoxin < 0.25 EU/mg, identity confirmed — before the lot is cleared.

05

Release & Ship

Only after the Certificate of Analysis is matched does the batch move to dispensing, cold-chain fulfillment, and tracking the unit all the way to delivery.

What the paperwork actually says.

Answers to the questions our patients actually ask.

Where are the peptides actually synthesized?
Every peptide PeptideVault ships is synthesized in the United States at a cGMP-certified facility. We do not source from overseas compounding brokers, raw-peptide importers, or research-chemical suppliers. The full chain — synthesis, dispensing, and shipping — sits on US soil.
What does a Certificate of Analysis actually verify?
The COA confirms identity (mass spectrometry matches the expected molecular weight), purity (HPLC trace shows a single dominant peak of at least 98%), sterility (endotoxin below a defined LAL threshold), and the absence of residual solvents. The verifying lab is always independent and third-party — never an internal QA pass at the same site that produced the batch.
Who runs the third-party tests?
Independent laboratories we do not own or operate. Every batch ships with a COA document naming the verifying lab, the test methods used (HPLC, MS, LAL, etc.), the test date, and the result for each release-spec parameter. The lab's accreditation is documented in the COA PDF.
How is cold-chain custody preserved?
Lyophilized peptides are shipped in temperature-controlled packaging with insulation and — when warranted — refrigerant packs. The batch record travels with the unit: synthesis date, COA, dispensing pharmacy, and shipping timestamp are all logged so the receipt condition can be verified on delivery.
Are these peptides FDA-approved?
The peptides discussed on this site have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease. They are dispensed patient-specifically through licensed 503A compounding pharmacies under a physician-signed prescription, in compliance with applicable federal and state law.
