Great product, larger sizes welcome
Solid sourcing and presentation. For long-duration studies I would benefit from larger vial format options. Otherwise the product itself is excellent.

Consistent batch after batch
Third order now and every COA has come back above 99%. That consistency is what keeps me coming back. Packaging is excellent for long-distance cold shipping.

Exceptional for longevity research
Quality is outstanding — third-party verified and matches the COA precisely. Pepthera has become our go-to supplier. Fast shipping and responsive support team.

Operational maturity shows
Order acknowledgement within minutes, shipping confirmation with tracking the next morning, delivery exactly when promised. This is the level of operational discipline I expect from a serious supplier.

Storage instructions were genuinely useful
Most suppliers ship the vial and assume the buyer knows the rest. The handling guide included actually walked through pre- and post-reconstitution storage windows. Small thing — meaningful difference.

Tracked our internal HPLC within 0.1%
Cross-verified against our column. Pepthera-stated purity sat 0.08% above our own reading. That alignment, repeatedly, is the entire reason I switched.
