Independent peptide testing verifies what's actually inside the vial you purchased. This guide explains three types of analytical tests — HPLC purity, endotoxin screening, and quantity verification — how to submit samples to accredited testing laboratories, and what to expect in cost and turnaround time. For published results, browse the lab tests database.
| Test type | Cost / sample | Turnaround |
|---|---|---|
| HPLC Purity Analysis | $50–100 | 5–10 days |
| Endotoxin Screening (LAL) | $30–60 | 3–7 days |
| Quantity Verification | $0–50 | 5–10 days |
| Mass Spectrometry (Identity) | $40–80 | 5–10 days |
| Full panel (all tests) | $80–150 | 7–14 days |
Volume discounts available at most laboratories. Contact labs directly for current pricing — these ranges reflect typical published rates and may vary by region and sample preparation requirements.
After receiving your Certificate of Analysis, submit the results to the lab tests database. Published test results contribute to trust scores for peptide shops, help other buyers compare brands, and build a transparent quality record for the peptide market. Currently 6,168 tests are on file from 27 verified labs.
Each submission requires four pieces of information: the peptide name, the brand name, the purity percentage, and the testing laboratory name. Endotoxin levels, batch numbers, and container descriptions are optional but recommended.
We can't test peptides on your behalf, but we can point you to a lab and explain what each report covers. Typical response within 72 hours.
