Frequently asked questions.

Are peptides safe?

Peptides are short chains of amino acids — the building blocks of protein — that naturally occur in your body. When prescribed by a physician and sourced from licensed compounding pharmacies, they have an excellent safety profile. Your physician will review your full health history before prescribing.

Do I need a prior prescription?

No. Our licensed physicians handle everything. You'll complete a health intake form and our medical team will determine whether peptide therapy is appropriate for you and which protocols fit your goals.

How are peptides administered?

Most peptide protocols use subcutaneous injections — a small insulin-style needle administered just under the skin. Some peptides are available in oral, nasal, or topical form. Your physician will discuss the best route of administration for your protocol.

Does insurance cover this?

Most insurance plans do not cover peptide therapy. All pricing is out-of-pocket and shown transparently upfront. HSA/FSA cards may be eligible — check with your plan administrator.

How quickly will I see results?

It varies by peptide and individual. Some members report improvements in energy and sleep within the first 2 weeks. Body composition changes typically become visible at the 6–12 week mark. Your physician will set realistic expectations based on your specific protocol.

Can I cancel my subscription?

Yes. You can cancel anytime from your account dashboard with no cancellation fees. Annual plans are refunded pro-rata if cancelled within the first 30 days.
