Common questions
Straight answers
No hedging, no protest-too-much slogans. The certificate does the talking.
Are your peptides third-party tested?
Every batch is analyzed by Freedom Diagnostics, an independent US laboratory — identity by mass spectrometry (LC-MS), purity by HPLC. The certificate for your exact lot is searchable on the Verify page and included with your order.
What does the purity percentage mean?
It is the HPLC purity measured for that specific lot, reported directly from the certificate of analysis. We publish one number per batch — the same figure on the product page, the certificate, and your packaging.
How fast do orders ship?
In-stock orders placed before the Monday–Friday cutoff dispatch the same day from the US, with discreet, tracked packaging. The full catalog is kept in stock — no backorders.
