Transdermal delivery
Delivery of a peptide through the skin, typically via patches, creams, or gels. Provides sustained release but is limited by molecular weight — most peptides are too large for passive transdermal absorption.
Frequently Asked Questions
What is Transdermal delivery?
Delivery of a peptide through the skin, typically via patches, creams, or gels. Provides sustained release but is limited by molecular weight — most peptides are too large for passive transdermal absorption.
Why is Transdermal delivery important in peptide research?
Understanding transdermal delivery is essential for safe and effective peptide use. Proper administration technique directly impacts peptide bioavailability, therapeutic outcomes, and minimizes the risk of adverse effects or contamination.

Topical application
Application of a peptide directly to the skin surface for local effects. Common for copper peptides (GHK-Cu) in skincare and BPC-157 formulations targeting localized injury sites.
BioavailabilityThe fraction of an administered dose that reaches systemic circulation unchanged. Subcutaneous injection provides 65–95% bioavailability for most peptides; oral bioavailability is typically below 1% without absorption enhancers.
