Peptide therapy for muscle, recovery & performance.

Peptides are short chains of amino acids — the same building blocks as proteins — that act as precise signaling molecules in the body. Therapeutic peptides use those signals to support specific functions: growth-hormone release, cellular energy, fat metabolism, antioxidant capacity, or sexual desire. Your body already makes and uses thousands of them.

You complete a 5-minute online health intake, a licensed Affinity provider reviews it, typically within 24 hours, and if treatment is clinically appropriate they issue a prescription. Your medication is compounded by a licensed U.S. pharmacy and shipped free with 2-day delivery once your prescription is filled, with everything you need included. If a provider does not approve treatment, you receive a full refund.

Yes. Every protocol is prescribed by a licensed Affinity Whole Health provider — the same clinical team behind our 4 physical Midwest clinics, treating patients since 2012. Nothing here is sold as a "research chemical," and nothing ships without a provider's prescription.

It varies by protocol and person. Sleep and energy changes are often noticed in the first few weeks (Sermorelin, NAD+); skin and body-composition changes typically build over 8–12 weeks of consistent use. PT-141 works on-demand, about 45 minutes after a dose. Your provider sets realistic expectations for your specific protocol.

Everything: your pharmacy-compounded peptide vial, sterile insulin syringes, alcohol prep pads, free 2-day shipping in discreet packaging, and the provider review itself. One all-in price — no membership, no consult fee, no hidden costs.

These protocols use a small insulin needle injected into fatty tissue (abdomen or thigh) — most patients describe it as nearly painless. We include step-by-step guidance, and your care team is a message away if you want a walkthrough. No clinic visits required.

Often yes — many peptides are used alongside hormone or GLP-1 programs. Combination use should always be provider-supervised: your Affinity provider reviews your full medication list during intake and only prescribes what is safe with your current regimen.

Healthy adults with specific goals — recovery, sleep, energy, body composition, skin health, or sexual wellness — are typically good candidates. Some conditions rule out specific peptides (for example, a cancer history for Sermorelin or NAD+, asthma for glutathione, uncontrolled blood pressure for PT-141). Your provider screens for all of this during intake.

No membership and no lock-in. You buy a supply; refills are provider-supervised and on your schedule. There is no recurring membership fee like many telehealth peptide programs charge.

Ongoing access to your care team — message anytime with questions about dosing, side effects, or progress. Dose adjustments and follow-ups are handled by the same licensed providers, backed by a real clinic network, at no extra consult fee.
