Delivery of a substance through the skin into systemic circulation, typically via patches or specialized creams. Peptides generally have poor transdermal absorption due to their size, though emerging technologies like microneedle patches aim to overcome this.
"Transdermal" is filed under Administration in the PeptideAtlas glossary, alongside 15 other terms in that group.
The term applies directly to 1 compound profile here: Pal-GHK (Palmitoyl Tripeptide-1) (evidence D). Each profile states the strength of the human evidence rather than only what the compound is claimed to do.
An injection administered into the fatty tissue layer between the skin and muscle. The most common route for peptide self-administration.
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.
Compounds where this applies: Pal-GHK (Palmitoyl Tripeptide-1).
More Administration terms: Subcutaneous (SubQ), Intramuscular (IM), Intravenous (IV), Intranasal, Sublingual, Topical Peptide, Microneedle Patch, Insulin Syringe, Titration, Loading Dose, Maintenance Dose, Peptide Stack, Lipohypertrophy, Injection Site Rotation, Intranasal Delivery.
