503A vs cGMP: what's the difference?
Many peptides on Celvara are offered in both formats. The compound is the same — the difference is how it is prepared, priced, and regulated. Choose the format that fits your preference; an independent licensed provider reviews every order.
Compounded, ready to inject
Sourced from a state-licensed 503A compounding pharmacy. Arrives in solution — no reconstitution required. Use as directed by your prescribing provider. An $85 provider consult is optional and recommended for first-time protocols — add it at checkout if you want one-on-one guidance.
Freeze-dried — you mix it yourself
Sourced from an FDA-registered outsourcing facility operating under current Good Manufacturing Practice (cGMP). Ships as a freeze-dried powder; you reconstitute with bacteriostatic water per the included instructions. Generally a lower price point. An optional $85 provider consult is available as an add-on.
