Frequently Asked Questions

No. All products sold by Valid Vials are strictly for in-vitro laboratory and research use only. They are not approved for human or veterinary consumption, and we do not support any such use.
Every order includes the product, a lot-specific Certificate of Analysis from an independent lab, and discreet packaging with tracking. No branded exterior.
Lyophilized (freeze-dried) peptides should be stored at −20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2–8°C and use within 4–6 weeks.
Orders are fulfilled within 1–2 business days. You'll receive tracking information via email once your order ships. All peptides ship with cold packs to maintain integrity in transit.
Use our bacteriostatic water for reconstitution. Inject the BAC water slowly along the side of the vial (not directly onto the powder). Gently swirl — never shake. The solution should be clear.
We accept all major credit and debit cards via our secure Stripe-powered checkout. Your payment information is encrypted and never stored on our servers.
⚠️ Research Use Only. All products are sold exclusively for laboratory and in-vitro research. Not for human or veterinary consumption. These compounds have not been evaluated by the FDA. Researchers are solely responsible for compliance with all applicable local, state, and federal laws.
