Comparing quotes? Ask one question.

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.

Peptide testing FAQ

Is endotoxin enough to call a peptide "injectable grade"?

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.

Do you run true USP <71> sterility in-house?

Yes — the full 14-day USP <71> sterility test is performed in our own lab, not outsourced or substituted with a bioburden count.

Do you charge method-development fees?

Not for established, in-literature peptides — we absorb that cost. A one-time fee applies only to genuinely novel or custom sequences.

Do you test semaglutide, tirzepatide, or retatrutide?

Yes, for analytical/research purposes, with a signed Tier-2 acknowledgment and an analytical-only disclaimer on the COA.

Do you accept samples from individuals?

Yes — individuals are welcome with a signed analytical-only attestation. We also serve vendors, clinics, and compounding pharmacies.

Are you ISO 17025 accredited?

ISO 17025 accreditation is in progress. Compendial safety testing (endotoxin USP <85>, bioburden USP <61>, sterility USP <71>) follows established USP methods on qualified instruments. Our in-house peptide identity/purity methods are currently in validation — ask us for the current status on your specific peptide.
