Does the panel include a true USP <71> sterility test (full 14-day incubation), or just a bioburden count (USP <61>)? That's usually the price difference. Our Screening tier ($750) covers identity, purity, net content, endotoxin, heavy metals, and bioburden; Release ($1,195) adds the true USP <71> sterility test. Many lower-priced "injectable" panels are screening/bioburden — not a true sterility test — so it's worth confirming when you compare.
No. Endotoxin (USP <85>) only measures pyrogens. A true injectable claim also needs sterility (USP <71>) — which is why it's the defining test in Tier 3. Endotoxin pass/fail also depends on your intended max dose.
Yes — the full 14-day USP <71> sterility test is performed in our own lab, not outsourced or substituted with a bioburden count.
Not for established, in-literature peptides — we absorb that cost. A one-time fee applies only to genuinely novel or custom sequences.
Yes, for analytical/research purposes, with a signed Tier-2 acknowledgment and an analytical-only disclaimer on the COA.
Yes — individuals are welcome with a signed analytical-only attestation. We also serve vendors, clinics, and compounding pharmacies.
Accreditation is in progress. Today our methods are validated to USP <1225> and run on qualified instruments, with true in-house compendial sterility and endotoxin testing.
