Peptides we test.
Mail us a vial and we confirm identity, chromatographic purity, and net-peptide assay (mg/vial) by RP-HPLC-UV, as a verifiable certificate of analysis. Pick a compound for the details below, or start an order.
Retatrutide
Triple-agonist metabolic peptide. Every run reports identity against a certified reference standard, chromatographic purity (area %) with impurity profile, and net-peptide assay in mg/vial. Submit a sample →
Tirzepatide
Dual GIP/GLP-1 agonist. Full impurity profile with chromatographic purity and net-peptide content — the two numbers that catch underfilled vials. Submit a sample →
Semaglutide
GLP-1 agonist on a validated RP-HPLC-UV method with reference-standard calibration. Results include retention-time match, purity and mg/vial assay. Look up a COA →
Tesamorelin
GHRH analogue. Identity confirmation plus quantitative purity and assay reporting on every certificate. Submit a sample →
BPC-157
Pentadecapeptide. Purity and net-peptide assay — see exactly what the report looks like in our sample certificate →
CJC-1295 + Ipamorelin (blend)
Two actives in one vial. Each compound is resolved against its own reference standard; blend vials are billed at the standard rate plus 50% for the second active (see pricing →).
AOD-9604
Modified hGH fragment analogue. Identity plus purity and assay reporting under the validated peptide method. Submit a sample →
TB-500
Thymosin beta-4 fragment. Quantitative purity with reference-standard assay and full certificate documentation. Submit a sample →
