An injection administered into the fatty tissue layer between the skin and muscle. The most common route for peptide self-administration.
"Subcutaneous (SubQ)" is filed under Administration in the PeptideAtlas glossary, alongside 15 other terms in that group.
An injection administered directly into a muscle. Some peptides may be administered via IM injection under medical supervision.
Administration directly into a vein. Provides 100% bioavailability but requires medical supervision and sterile technique.
Administration through the nasal mucosa. Some peptides (Semax, Selank, oxytocin) are administered intranasally to bypass GI degradation and potentially access the blood-brain barrier more directly.
