Mighty Peptides

Frequently asked questions

Everything you need to know about ordering research peptides from us.

What does “research use only” mean?+

All products are sold strictly for in-vitro laboratory and research purposes. They are not drugs, supplements, foods, or cosmetics, and may not be used for human or veterinary consumption. By purchasing, you confirm you are a qualified researcher or institution.

How is purity verified?+

Every batch is analyzed by an independent third-party lab using HPLC and mass spectrometry. A certificate of analysis (COA) confirming >99% purity is included with each order and available in your account.

How fast do orders ship?+

In-stock orders are dispatched within 24 business hours. Peptides are shipped lyophilized; cold-chain packaging is available at checkout for temperature-sensitive compounds.

How should peptides be stored?+

Lyophilized peptides are stable at room temperature for short periods but should be stored at -20°C for long-term storage. Once reconstituted, store at 2–8°C and use within the validated window described on the COA.

What payment methods do you accept?+

Payments are processed securely through Stripe, which accepts all major credit and debit cards. We never store your card details on our servers.

What is your return policy?+

Due to the sensitive nature of research materials, opened vials cannot be returned. Unopened, undamaged products may be returned within 14 days. Contact support to start a return.

Do you offer wholesale or bulk pricing?+

Yes. Institutions and high-volume researchers can request wholesale pricing through our contact page.
