Peptides, prescribed with a purpose.

Your body's own signals, restored.

Peptides are short chains of amino acids — the same building blocks your body uses to make every protein, hormone, and signaling molecule that keeps you functioning. As natural peptide production declines with age, so can recovery, sleep, skin repair, energy, libido, cognition, and resilience.

Peptide therapy is designed to restore those signaling peptides in pharmaceutical-grade form, under physician supervision. Every protocol at Rejuvia starts with a clinical intake and lab review, and each peptide is selected for a specific clinical rationale.

Most peptides are administered as simple subcutaneous self-injections on a dosing schedule your provider sets. Courses range from a single vial lasting a few weeks to multi-vial protocols running several months.

What to expect — and when.

• Recovery and healing peptides: effects typically appear within 2–4 weeks.
• Growth hormone peptides: build over 6–12 weeks, with the most noticeable changes in body composition, sleep, and recovery in months two and three.
• Longevity and cellular peptides: the longest timeline — consistent multi-month use — with benefits that often persist beyond treatment.

The most common side effect is a mild injection-site reaction — redness or itching — that typically resolves within a day. Some peptides may cause transient warmth, flushing, or a brief period of fatigue early on.

Who peptide therapy is for.

Most adults pursuing recovery, longevity, performance, or wellness optimization can be candidates after clinical screening. Peptide therapy is not appropriate for anyone pregnant or breastfeeding, those with an active malignancy or recent cancer history, or certain medical conditions we evaluate during your consultation. Growth hormone peptides require baseline lab work, and certain longevity peptides carry specific contraindications your provider reviews at initiation.
