Thymosin Alpha-1 is used in 35+ countries to enhance T-cell maturation and dendritic cell function — your immune system's front line. LL-37 is an antimicrobial peptide that fights bacteria, viruses, and fungi while disrupting biofilms.

Chronic Inflammatory Response Syndrome — a condition caused by exposure to biotoxins like mold. VIP is the final step in the Shoemaker protocol for treating CIRS.

The science

What are peptides?

Your body already makes them. We just give it more.

Think of peptides as text messages for your cells.

Peptides are short chains of amino acids — the same building blocks your body uses every day to heal injuries, burn fat, fight infection, and repair skin.

As you age, your body produces fewer of these signaling molecules. Peptide therapy replenishes them — giving your body the instructions it needs to recover faster, perform better, and look younger.

Every peptide we offer is prescribed by a licensed physician and compounded at an FDA-registered pharmacy. This isn't grey market supplements — this is real medicine.

How do they work?

Peptides bind to specific receptors on your cells and trigger targeted responses — like telling your body to increase collagen production, release growth hormone, or reduce inflammation.

Are they safe?

When prescribed by a licensed physician and compounded at a registered pharmacy, peptides have an excellent safety profile. Your doctor monitors your treatment and adjusts as needed.

How are they different from steroids?

Peptides work WITH your body's natural systems — they signal, they don't override. Steroids replace your hormones. Peptides tell your body to produce more of its own.

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. All orders ship in plain unmarked 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 in 45 U.S. states. We do not currently ship 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.
