Testing & Purity Verification

Peptide Sciences employs third-party HPLC testing to verify the purity of their peptide products. COAs are available on request and typically show purity levels of 98% or higher. While they do not currently include mass spectrometry as a standard test (unlike Swiss Chems), their HPLC results are performed by independent, accredited laboratories. The company also provides detailed product specifications including molecular weight, sequence, and physical properties for each compound.

Our Verdict

Peptide Sciences earns a strong 4.7/5 rating thanks to their extensive product range, credit card payment option, and established reputation. They are the ideal choice for researchers who need access to a wide variety of compounds from a single, trusted source. While their pricing is on the higher side, the convenience of credit card payments and the breadth of their catalog makes them worth the premium. For researchers on a tighter budget, consider Swiss Chems as an alternative with comparable quality at slightly lower price points.
