Subcutaneous Peptide Injection Protocol

The standard administration route for the majority of research and clinical peptides. Subcutaneous injection delivers the peptide into the fat layer under the skin, where it is absorbed gradually into the bloodstream.

How It Works

After reconstitution with bacteriostatic water, the desired dose is drawn into an insulin syringe (typically 29–31 gauge, 0.5 mL capacity). Injection sites include the abdomen (2+ inches from the umbilicus), thighs, or the fatty tissue near the injury site for regenerative peptides. Rotate sites to avoid local tissue hypertrophy or atrophy.

Benefits

Avoids first-pass liver metabolism that would destroy most peptides orally
Slower, more physiological absorption than IV
Easy to self-administer with insulin syringes
Well-tolerated, minimal pain with short 29-31G needles

Frequently Asked Questions

Is IM better than SubQ for peptides?
Rarely. Most peptides have been characterized pharmacokinetically via SubQ. IM accelerates absorption but is more painful and offers no therapeutic advantage for typical protocols.
