— Engineered for real clinical use

Built for your kitchen table,
documented for your doctor.

Peptide therapy is self-administered at home, daily or weekly — so the pen is engineered for exactly that: 1 unit click resolution, under 8 newtons of press force at therapeutic doses, and no syringe draw step. Behind it, your physician sees the actual fill records, tracking numbers, and lot data for your chart.

— The device

What the pen is,
in plain terms.

Two parts: a pen you keep, a cartridge you replace

The injector itself is reusable. It holds a 3 mL cartridge of your medication, compounded and filled by the pharmacy, and the cartridge is what gets replaced — by hand, no tools. The pen stays with you; the medication cycles through it. That is the whole design, and it is why the injector is free with your first order rather than something you buy again every month.

The dose dial, and what a “unit” means here

The dial runs from 0 to 60 units in single-unit clicks, and one unit is 0.01 mL — the same graduation an insulin syringe uses. Your pharmacy label states your dose in the same unit, so the number on the label is the number of clicks — there is no conversion to do and no syringe barrel to read against the light. That is the practical difference from a vial: with a vial you are measuring; with the pen you are counting.

It fires at under 8 newtons of press force at therapeutic doses. Most people describe feeling the click more than the needle.

What “510(k) cleared” means, and what it does not

The injector is a 510(k) cleared medical device. Clearance means the manufacturer demonstrated to the FDA that the device is substantially equivalent to a device already legally on the market, and the FDA allowed it to be sold. It is a different pathway from approval: an approved drug has been reviewed for safety and effectiveness in clinical trials, while a cleared device has been reviewed against an existing comparable device.

Two things follow, and both matter. The clearance covers the injector — the hardware that holds the cartridge and delivers the dose. It says nothing about the medication inside it. Compounded medications are not FDA approved, whichever format they arrive in, and no auto-injector changes that. Anyone implying otherwise is misreading the clearance.

The pen is produced in a cGMP, ISO 13485:2016 facility and takes ISO 11608 compatible needles and cartridges — the same standards the pen injectors used for insulin and GLP-1 medications are built to.

Needles, and what to do with them after

A fresh single-use tip goes on before each injection and comes off after. Reusing a tip dulls it, which is the usual reason an injection that was painless last week stings this week. Used tips go in a sharps container, not household rubbish or recycling, and the FDA publishes guidance on disposal where you live — rules are set locally, not nationally.

Storing it, and travelling with it

The cartridge follows the storage instructions printed on your pharmacy label — that label, not a website, is what governs your medication. The pen body itself is not refrigerated. If you fly, medication and the supplies that go with it are exempt from the liquid limit, but you have to declare them at the checkpoint, and cold packs may be presented frozen, partly frozen or melted.

If the pen is dropped, or a dose is interrupted part-way, do not re-dial and guess. Message your care team and say exactly what happened; guessing a partial dose is how a week of dosing goes wrong.

What the pen does not change

It does not change the medication, the strength, or what a physician will prescribe. The same peptide at the same strength is the same medication in a vial or a cartridge. It does not remove the need for a prescription, a physician review, or the lab work your prescriber asks for. It changes one thing: how the dose gets from the container into you.

Important legal & safety information

The assessment process available on the Pepti website asks a series of medical questions, and the answers provided are reviewed by an independent licensed physician affiliated with our partner physician network. The licensed providers have established exclusionary criteria, and the answers provided determine if the individual is screened out of eligibility for treatment. The licensed clinicians retain the sole decision to prescribe peptide therapy and other compounded medications to patients. Treatment may be denied at the physician's sole discretion. If a prescription is not approved, you will not be charged for the medication.

Pharmacy Providers. Pepti is a technology platform and is not a healthcare provider, pharmacy, or prescriber. All medications offered through the platform are compounded by independent FDA-registered 503A or 503B compounding pharmacies based on a valid prescription written by a licensed physician for an individual patient. Compounded medications are not FDA-approved as products. The active pharmaceutical ingredients used by our partner pharmacies are sourced from FDA-registered facilities. Compounded medications may not undergo the same testing or quality control as commercially manufactured FDA-approved drugs.

Results vary. Results from peptide therapy and other compounded treatments vary based on individual factors, including age, weight, medical history, adherence to the prescribed protocol, lifestyle factors, and physiological response. Pepti makes no guarantee of any specific outcome. Statements about peptide therapy and compounded medications offered through the platform have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.

Product images. Product photographs and renderings shown on this website are for illustrative purposes only. The appearance of vials, packaging, labeling, and other materials you receive may vary and is determined by the dispensing compounding pharmacy.

Off-label use.Many peptides offered through the platform are prescribed for off-label use. “Off-label” means the medication is being prescribed for a use, dose, or patient population that is not specifically approved by the FDA. Off-label prescribing is legal and common in U.S. medical practice when supported by clinical experience and judgment.

Mailing & shipping. Pepti currently dispenses prescription medication to patients in 50 states. All orders ship in unbranded, tamper-evident packaging via expedited delivery from our partner compounding pharmacies. Temperature-sensitive medications ship with insulated packaging and ice packs. Shipping is included at no additional cost. We do not currently ship medication outside 50 states, internationally, or to APO/FPO addresses.

Not for emergencies. Pepti is not designed for medical emergencies. If you are experiencing a medical emergency, call 911 or go to your nearest emergency room immediately. For urgent but non-emergency medical questions, contact your primary care provider or use an urgent care service.

No doctor-patient relationship with Pepti. Your use of the platform does not create a doctor-patient relationship between you and pepti LLC. A doctor-patient relationship is established only between you and the independent licensed physician who reviews your intake and prescribes your treatment. The physicians who use the platform are independent contractors and are solely responsible for the medical care they provide.

Prescription medications. All prescription products require a valid prescription from a licensed healthcare provider. By using the platform, you acknowledge that you are at least 18 years old and that the information you provide is true, accurate, current, and complete. Providing false information may result in inappropriate treatment recommendations or denial of service.

Cosmetic & wellness products.Certain products offered through Pepti — including skincare, hair care, body care, supplements, men's grooming, sports recovery, and sexual wellness products — are cosmetic or dietary supplement products, not prescription medications. These products do not require a prescription and are not reviewed or prescribed by a physician. Statements regarding dietary supplements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease. Results vary by individual. Consult your healthcare provider before starting any new supplement or topical product, especially if you are pregnant, nursing, or taking other medications.
