The process
How it works.
Celvara connects you with an independent licensed provider — we are not the provider ourselves.
01
Choose your peptide
Browse the catalog by goal — weight loss, recovery, aesthetic — and add the product you want to your cart.
02
Provider review
Once you place an order the Celvara team coordinates the prescription workflow with an independent licensed provider on your behalf.
03
Ship to your door
Approved orders ship directly from the sourcing pharmacy — 503A compounded or 503B lyophilized, depending on the product.

What's the difference between 503A and 503B?
Sourcing
What's the difference between 503A and 503B?
503A
Compounded, ready to inject
Sourced from a 503A compounding pharmacy. Arrives in solution — no reconstitution required. Use as directed by your prescribing provider. A Doctor Consultation ($49) is recommended with every 503A purchase to coordinate your prescription — added to your cart by default, and removable.
503B
Freeze-dried — you mix it yourself
Sourced from a 503B outsourcing facility under FDA cGMP oversight. Ships as a freeze-dried powder; you reconstitute with bacteriostatic water per the included instructions. Generally a lower price point — no consultation required.
Support
Frequently asked questions.
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.
What does the provider review involve?
After you order, the Celvara team coordinates an intake form and async review with an independent licensed provider. We don't make the medical decision — the provider does.
Do I need an existing prescription?
No. The provider review handles the prescription as part of the post-order flow. If a product isn't appropriate for you, the provider will tell you and you won't be charged for the prescription portion.
How should I store my peptides?
503A compounded vials ship refrigerated and should stay refrigerated. 503B lyophilized powders are shelf-stable until reconstituted; refrigerate once mixed. Specifics are on each product's label.
What dose should I take?
Dosing is a clinical decision and lives with your prescribing provider, not with the storefront. Follow the protocol the provider sends you.
What about returns?
Compounded medications are non-returnable per federal regulation once dispensed. If a shipment arrives damaged, contact us within 48 hours and we'll coordinate a replacement.
What payment methods do you accept?
All major credit cards through our processor. Your card is charged when the order is placed; if the provider declines the prescription, the prescription portion is refunded.
Is my information secure?
Payment is handled by our PCI-compliant processor; we never store full card numbers. Health information shared with the provider is handled under their privacy policy.
