Peptide therapy, simplified
Peptides are signals
Short chains of amino acids that tell cells what to do.
Each has one job
Different peptides target different goals, from appetite to skin.
Prescription only
A licensed provider decides if a peptide fits you.
Plans are personal
Your dose and schedule are set and adjusted with check-ins.
The science
How does peptide therapy work?
Your body already makes thousands of peptides. Therapeutic peptides are designed to copy or support specific ones, so a clear signal reaches the right place.
1. The peptide is given
Usually a small injection under the skin, on a schedule your provider sets.
2. It finds its receptor
Each peptide fits specific receptors, like a key fits a lock.
3. Your body responds
That signal prompts a targeted response, such as feeling full sooner.
Options at Onus
What types of peptides are there?
These are the peptide therapies Onus offers. Your provider will recommend one, or none, based on your goals and health history.
Semaglutide
A GLP-1 medication that quiets hunger and helps manage blood sugar.
Tirzepatide
A dual GIP and GLP-1 medication for stronger appetite control.
Sermorelin
Encourages your body's natural release of growth hormone. Research suggests it may support sleep, recovery, and body composition.
GHK-Cu (Glow)
A naturally occurring copper peptide that research suggests may support skin health and collagen.
BPC-157
Studied, mostly in the lab and in animals, for its possible role in tissue repair.

Safety
Is peptide therapy safe?
Safety depends on the specific peptide, your health history, and medical supervision. Some peptides, like semaglutide and tirzepatide, are widely studied. Others, like BPC-157, have mostly early research. That's why every Onus plan starts with a consult, is prescribed by a licensed provider, and includes regular check-ins. Our peptides are sourced from a U.S.-based manufacturer.
