Are these research chemicals?
No. Every Optimino Rx product is compounded by a licensed 503A pharmacy for an individual patient and dispensed after review by a licensed provider. It is pharmacy-grade medication, not a "research use only" product.
Do I need a prescription?
You don't need to bring one. Add what you want to your cart and complete a short intake at checkout. A licensed provider reviews it, and if approved, writes the prescription for you.
How do I take them?
Most peptides are a small subcutaneous injection. Many are also available as a needle-free nasal spray. Your order ships with dosing instructions from your provider.
What's the difference between a vial and a kit?
A kit is ten vials of the same peptide in one order, so you have a full protocol on hand without reordering.
Do I need bacteriostatic water?
Yes, for any injectable vial. Peptides ship as a freeze-dried powder for stability. Add Reconstitution Solution to your cart to mix them.
