Sequence signatures
Written in the molecule.
Semaglutide
Aib at position 2 resists the enzyme DPP-4. A C18 fatty diacid on lysine 20 (Lys26 in GLP-1 numbering) binds albumin, stretching its half-life to about a week.

Tirzepatide
Aib at positions 2 and 13, and a C20 fatty diacid on lysine 20 that binds albumin, for a half-life of about five days.

How it works
Care starts with a clinician.
When consultations open, every prescription will start with a licensed clinician in your state, and every medication will come from a licensed pharmacy.
- 01
Consult online
Tell us what you’re interested in and complete a medical intake.
- 02
A clinician decides
A licensed clinician reviews your history and prescribes only if a treatment is appropriate for you. Sometimes the answer is no.
- 03
A pharmacy dispenses
A licensed U.S. pharmacy fills the prescription and ships it discreetly, cold-packed when the medication needs it.
Transparency
Every status.
In plain sight.
Most of the peptides people search for aren’t FDA-approved. We profile them anyway, and give every one an honest status so you know exactly where it stands.
FDA-approved · by prescription
FDA-approved brand-name medicines, or medicines compounded by a licensed pharmacy where the law allows. Prescribed only after a clinician review.
FDA-approved for a specific condition · specialist care only
Approved for a specific condition and managed by specialists. We explain them; we don’t offer them.
Not FDA-approved · not available for sale or prescription
FDA advisory vote, July 2026 · FDA staff opposed · no FDA action
In July 2026 an FDA advisory committee voted to recommend them for compounding, over FDA staff’s objection. FDA hasn’t acted. They are not approved and not available for sale or prescription.
Investigational · not approved · not available for sale or prescription
Still in clinical trials. Not approved anywhere.
Not FDA-approved · not available for sale or prescription
Not FDA-approved and not available for sale or prescription. Profiled because people ask about them.
Cosmetic ingredient · not sold by RiptideRx
Ingredients used in cosmetic skincare. We explain them; we don’t sell them.
