SubQ

Subcutaneous (subQ) peptides are short chains of amino acids injected into the fatty layer just beneath the skin, using a very small needle. From there they absorb slowly into the bloodstream, which makes dosing gentle and steady. It's the most common delivery method for peptides because it's simple, bioavailable, and easy for patients to do at home after brief training. Compared to oral capsule options, subQ avoids digestive breakdown, so more of the peptide reaches circulation. Compared to IM injections, it's shallower, less intimidating, and typically more comfortable.
