Side-by-Side Comparison

Aspect	DSIP	GHK-Cu (Copper Peptide)
Dose Range	100 mcg–300 mcg	1 mg–2 mg
Frequency	1x daily	1x daily
Cycle Length	1–6 weeks	4–8 weeks
Route	subcutaneous	subcutaneous
Mechanism	Modulates sleep-wake cycles by affecting sleep spindles and delta rhythms. May also influence stress hormones and have analgesic properties.	Attracts immune cells and fibroblasts to wound sites, stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, and has antioxidant effects. Modulates gene expression related to tissue repair.
Typical Dosage	Typical dosing: 100-300mcg administered 30 minutes before sleep. Some protocols use it cyclically.	Topical: Applied as serum or cream 1-2 times daily. Injectable: 1-2mg daily for research purposes. Microneedling protocols often use 0.5-1%.
Administration	Subcutaneous or intramuscular injection before bedtime. Some users report better results with cyclical use.	Most commonly used topically for skin applications. Can be injected subcutaneously for systemic effects. Often combined with microneedling for enhanced skin penetration.
Side Effects	May cause grogginess upon waking, vivid dreams, or temporary headaches.	Topical use is generally well-tolerated. May cause temporary skin irritation or redness in sensitive individuals. Injectable use may cause injection site reactions.
