Subcutaneous Injection
Also known as SQ Injection · SC Injection
Injection into the fatty layer just below the skin — the standard route for peptide dosing, self-administered with an insulin syringe.
Definition
Subcutaneous injection places the dose into the adipose layer below the dermis, where absorption is steady and slow. The standard tool is a 30- or 31-gauge insulin syringe with a half-inch needle; common sites are the periumbilical abdomen, the outer thigh and the deltoid. Self-injection is painless for most members after the first few attempts and is the default route across the peptide catalog.

Bioavailability
The fraction of a dose that reaches circulation in active form — a key reason most peptides are injected subcutaneously rather than taken orally.
Delivery & DosingLyophilisationFreeze-Drying
The freeze-drying process used to stabilise peptides for shipping — the vial you reconstitute with bacteriostatic water on arrival.
Delivery & DosingReconstitution
Mixing bacteriostatic water into a freeze-dried peptide vial to create a usable solution — the step every member does on arrival.
