Testing & sourcing
Transparency about where your peptides come from and how orders are reviewed — without medical outcome claims or downloadable Certificates of Analysis.
503A compounding pharmacies
503A products are prepared by state-licensed compounding pharmacies under state board oversight. These pharmacies compound patient-specific preparations — including pre-mixed peptide solutions ready to inject. Celvara works with licensed 503A partners that meet our sourcing standards.
cGMP outsourcing facilities
cGMP products come from FDA-registered outsourcing facilities operating under current Good Manufacturing Practice (cGMP). These facilities produce larger batches of lyophilized (freeze-dried) peptides that you reconstitute at home with bacteriostatic water. cGMP is often the lower-cost format for the same compound.
Third-party testing
Peptides sourced through Celvara are subject to third-party testing standards at the facility level. We verify partner credentials and quality processes — but we do not publish Certificates of Analysis (COAs) on this website. If you have questions about a specific batch, contact our support team.
Independent licensed providers
Every prescription product order is reviewed by an independent licensed provider — not by Celvara staff. Celvara coordinates the connection between you, the provider, and the pharmacy. Celvara is a storefront and coordination platform; it is not the prescribing provider.
