1

Share your health history

Every treatment has its own online clinical questionnaire — your history, medications, and goals.

2

Your answers get a careful review

A clinician reads your history and takes the time to get it right before anything is prescribed.

3

Your pharmacy ships

Compounded for your prescription and shipped cold-chain, with care-team check-ins after.

The safe way to take this seriously

These medications are easy to find online and hard to trust there. Promise works the way medicine is supposed to work — a clinician decides, a licensed pharmacy fills, and someone stays accountable to you.

A real prescription

Prescribed for you specifically, after a real look at your health history — never pulled off a shelf.

A real pharmacy

Your prescription is compounded for you by a licensed U.S. pharmacy — not a mystery vial from an unregulated website.

Real oversight

Temperature-safe shipping, follow-up check-ins, and a care team that answers — before and after your medication arrives.

In brief.

The catalog below is everything Promise offers — no hidden tiers, no separate list. Every card links to a full page for that treatment: what it is, how it's supplied, what it costs, and what the published research actually says, in plain language.

How the catalog is organized

Treatments are grouped by the goal they're most often considered for, mirroring our ten solution hubs — from metabolic support & fat loss to muscle & recovery, energy & focus, and immune support. Prefer to start from the goal and work back to the treatment? The hubs are the better front door. Already know the compound you're looking for? The grid above is the fastest path.

How to choose between peptide treatments

Start with the goal, not the molecule. Each group heading links to its hub, which explains what that category's treatments are studied for and how they differ. Then read the treatment's own page before starting a visit — it carries the price, what's included, and the fine print, stated plainly. And hold the choice loosely: whichever questionnaire you begin, a licensed provider reviews your full health history and prescribes only what genuinely fits it.

What happens after you pick

Every treatment routes through its own clinical intake — a questionnaire written for that specific medication, never a generic form. A licensed provider reviews every request. If a prescription is written, a licensed U.S. pharmacy compounds it for you and ships it in temperature-safe packaging, with care-team check-ins after.

Common questions

How does the online visit work?

Each treatment has its own clinical questionnaire covering your health history, medications, and goals. A licensed provider reviews your answers and prescribes only when the treatment is a genuine fit for you. If it is, a licensed U.S. pharmacy compounds your prescription and ships it in temperature-safe packaging, with care-team check-ins after.

Why is everything prescription-only?

Because these are medications, not supplements. A prescription means a licensed clinician has looked at your health history and decided the treatment fits it — and it means your medication comes from a licensed U.S. pharmacy instead of an unregulated website. The review is the product; the vial is the last step.

Are these treatments FDA-approved?

No. FDA-approved versions of some of these molecules exist, but the compounded formulations offered here are not FDA-approved. Compounded medications are not reviewed by the FDA for safety, effectiveness, or quality. They are prepared by a licensed U.S. compounding pharmacy against a prescription written for you specifically.

What do treatments cost?

Each product page lists its price, including single-month and multi-month options where they exist, and the price is shown before you start a visit. Not every treatment is available in every state.
