Frequently asked questions

How does Pepnerd grade the evidence for each compound?

Each compound carries an evidence tier (preclinical → approved) and, where available, a clinical phase. These summarise the published literature for reference only and are not clinical guidance.

Can these compounds be combined in research protocols?

Some are studied together to target complementary pathways. Avoid duplicating a compound that already appears in a blend, and check each dossier's do-not-combine list for documented interactions.

How are these compounds administered in research?

Route of administration varies by compound — most commonly subcutaneous, with some intranasal or topical. Check each product's dossier. All Pepnerd materials are for in-vitro research use only and are not for human or veterinary use.

Do Pepnerd peptides include third-party testing?

Yes — every batch ships with a Certificate of Analysis. You can also send any order for independent testing and share the results for a free vial on your next order.
