Questions, answered.

What is Pepti?

Pepti is a peptide telehealth platform serving all 50 states and Washington, D.C. You complete a free online assessment, a licensed physician reviews your case, and if treatment is appropriate your prescription is compounded by an FDA-registered US pharmacy and shipped to your door.

What are peptides?

Peptides are short chains of amino acids that act as signaling molecules in the body — many occur naturally and are involved in recovery, metabolism, sleep, and other core processes. The peptides Pepti offers are prescription treatments, prepared for an individual patient by a compounding pharmacy after physician review.

Do I need a prescription?

Yes — every treatment is prescription-only. A licensed physician reviews your intake before anything is prescribed, and the physician review is included in your price: there's no separate visit fee. If you're not approved, you're fully refunded.

How much does it cost?

One all-in monthly price per treatment — medication, physician care, and shipping included. Treatments start at $99/month, and every price is published on its product page before you start.

Is Pepti legitimate?

Pepti works only with licensed US physicians listed by name on our providers page, and fills every prescription through FDA-registered 503A/503B compounding pharmacies. Compounded medications are not FDA-approved; a licensed provider determines whether treatment is appropriate for you.

Is my medication tested?

Yes. Every medication is compounded by a PCAB-accredited, FDA-registered US pharmacy, and independent labs test lots for sterility, bacterial endotoxin and potency. Pepti publishes the results by lot number (561 lot reports published · 561 of 561 sterility pass · 561 of 561 endotoxin pass · potency reported on every lot) at hellopepti.com/quality/lab-results. Batch-specific Certificates of Analysis are available to patients on request.

Is Pepti available in my state?

Yes — Pepti serves all 50 states and Washington, D.C. through telehealth. No clinic visits: intake, physician review, and care-team messaging all happen online or in the iPhone app, and your medication ships directly to you.

How fast will my medication arrive?

A physician typically reviews your case within 24 hours of a completed intake, and approved prescriptions ship from the pharmacy with free shipping — most patients receive their medication within days.

Do I have to inject myself?

Many treatments are subcutaneous injections with a small insulin-style needle — most patients find them quick and nearly painless, and full instructions are included. Prefer not to handle vials and syringes? Several treatments are available as the pre-filled pepti Pen, and others come as nasal sprays or capsules.
