Frequently Asked Questions

Everything you need to know about our products and processes.

What's the actual amount in each vial?

Each vial contains exactly what’s shown on the label. For example, a 10mg vial has exactly 10mg of lyophilized peptide. Researchers can divide it into smaller portions but the total amount remains 10mg.

Are additional supplies needed?

Peptides are supplied as lyophilized powder. They do not come reconstituted, and any extra supplies must be sourced separately for research applications.

How long does a vial last?

In lyophilized powder form, peptides stay stable for up to 2 years. After reconstitution, it should be refrigerated and is generally stable for up to 2 months.

Does the product come with instructions?

Vials ship lyophilized with a lot-specific COA. No protocols, solvents, or supplies are included.

How should I store these products?

Lyophilized peptides should be stored away from heat and light. Once reconstituted, they must be refrigerated to maintain stability.
