Good to know.
Are these products for human use?
No. Every product is sold strictly for laboratory and research use only (RUO). They are not for human or veterinary use, and nothing on this site is a drug, supplement, food, or treatment.
What does “third-party tested” mean?
Each lot is analyzed by an independent laboratory using HPLC-MS for identity and purity, plus sterility and endotoxin panels. The certificate is published under the lot number so you can read it yourself.
How do I verify a lot?
Enter the lot number printed on your vial or box on our Verify page and you’ll see the certificate for that exact batch.
How does volume pricing work?
Discounts apply automatically at checkout — 7% on 3+ vials, 11% on 5+, and 16% on 10+. No codes needed; the discount shows in your cart.
How is everything shipped?
Lyophilized peptides ship from the US in insulated packaging, typically within 1–2 business days. Shipping is free on orders over $200.
How should material be stored?
Store lyophilized peptides cold and away from light per the handling notes on each label. Storage guidance is provided for laboratory handling only.
What payment methods do you accept?
Card and ACH payments are processed securely through Kashu Pay at checkout.
Do you accept returns?
Because these are sensitive research materials, unopened items can be returned within 14 days. See our Shipping & Returns policy for details.
