Side-by-Side Comparison

Aspect	Humanin	Matrixyl
Dose Range	100 mcg–500 mcg	500 mcg–2 mg
Frequency	1x daily	2x daily
Cycle Length	4–8 weeks	4–12 weeks
Route	subcutaneous	topical
Mechanism	Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress.	Mimics collagen breakdown fragments, triggering fibroblasts to produce new collagen, elastin, and other matrix components. Essentially tricks skin into repair mode without actual damage.
Typical Dosage	Research protocols vary widely. Studies have used doses from micrograms to milligrams depending on the analog and route. HNG (S14G-Humanin) is a more potent analog.	Topical: 2-8% concentration in serums and creams. Matrixyl 3000 combines it with Palmitoyl Tetrapeptide-7 for enhanced effects.
Administration	Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities.	Topical application 1-2 times daily. Can be combined with other actives like retinol, vitamin C, and other peptides.
Side Effects	Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism.	Very well-tolerated. Rare mild irritation. Suitable for sensitive skin types.
