Frequently asked

What does the provider review involve?

After you order, Vivere Peptides coordinates an intake form and async review with an independent licensed provider through OutfitMD. We don't make the medical decision — the provider does.

How quickly do orders ship?

Once your prescription is reviewed and approved by an independent licensed provider, the sourcing pharmacy ships within 2–5 business days. Tracking lands in your email.

How should I store my peptides?

503A compounded vials ship refrigerated and should stay refrigerated. cGMP lyophilized powders are shelf-stable until reconstituted; refrigerate once mixed. Specifics are on each product's label.
