PS Peptides

ExcellentLast updated September 1, 2026

Second biggest catalog, including GLPs, with average prices in the same tier as Midwest Peptides and BioEdge Research.

Documented strengths

✓Four separate laboratory reports per lot rather than one merged certificate.
✓Every entry carries an N.A. Diagnostics Test ID and a matching PSP batch identifier.
✓Measured content is reported alongside purity, not in place of it.
✓Historical and superseded reports remain accessible.

—Several catalog items — including tablet products and a handful of vial strengths — still lack a complete four-report package and are excluded from the product list here.
—The expanded documentation is recent; consistency should be re-checked on future lots rather than assumed.
