Side-by-Side Comparison

Aspect	MOTS-c	Palmitoyl Tripeptide-1
Dose Range	5 mg–10 mg	500 mcg–2 mg
Frequency	Less than daily	2x daily
Cycle Length	8–12 weeks	4–12 weeks
Route	subcutaneous	topical
Mechanism	Activates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis.	Mimics the skin's own mechanism for producing collagen by acting as a messenger peptide that signals fibroblasts to produce more collagen and other extracellular matrix components.
Typical Dosage	Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established.	Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000.
Administration	Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation.	Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions.
Side Effects	Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance.	Very well-tolerated. Suitable for most skin types including sensitive skin.
