Where do peptides
get injected?
Pick a peptide (or a route) and the commonly-referenced subcutaneous injection zones light up on the body map. Front and back views, with notes on each site. For education and research reference only.
Front
Back
Subcutaneous — general sites
Most research peptides are studied via subcutaneous injection into the fatty tissue just under the skin. The abdomen is the most commonly referenced site, with the thigh and back of the arm as alternatives.
// What others report
Anecdotal experiences shared within the research community — not medical advice, and individual reactions vary.
// Why rotate sites?
Repeatedly injecting the same spot can cause irritation, lumps, or scar tissue over time. The general guidance in the literature is to rotate between zones — and within a zone, vary the exact spot each time. The highlighted areas show the commonly-referenced options to rotate through.

This body map shows general anatomical zones commonly referenced in research literature for subcutaneous injection. It is not medical advice, not personalized instruction, and not a substitute for guidance from a licensed healthcare provider. Research peptides are not approved by the FDA for human consumption.
