Kisspeptin-10 vs PEG-MGF
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Kisspeptin-10
Kisspeptin-10 is the active fragment of kisspeptin, a hormone that plays a crucial role in initiating puberty and regulating reproductive function. It acts upstream of GnRH in the hypothalamic-pituitary-gonadal axis.
Full details →PEG-MGF
PEG-MGF (PEGylated Mechano Growth Factor) is a variant of IGF-1 that is produced in response to muscle damage. PEGylation extends its half-life from minutes to several hours, making it practical for use.

| Aspect | Kisspeptin-10 | PEG-MGF |
|---|---|---|
| Mechanism | Binds to KISS1R receptors in the hypothalamus, stimulating GnRH neurons to release GnRH. This triggers the downstream cascade of LH, FSH, and sex hormone production. | Activates muscle satellite cells (stem cells) and promotes their fusion to existing muscle fibers for repair and growth. MGF is produced naturally in response to mechanical stress on muscles. |
| Typical Dosage | Research protocols vary widely. Studies have used IV boluses of 1-10mcg/kg or subcutaneous administration. Clinical applications still being developed. | Research protocols typically use 200-400mcg injected into targeted muscle groups 2-3 times weekly, usually post-workout. |
| Administration | IV or subcutaneous injection. Has very short half-life requiring frequent administration or continuous infusion for sustained effects. | Intramuscular injection, ideally into muscles trained that day. Best administered post-workout when satellite cell activation is relevant. |
| Side Effects | Limited data. May cause flushing, increased heart rate, and changes in libido. Generally well-tolerated in studies. | Injection site soreness, potential hypoglycemia, and localized swelling. Generally well-tolerated. |
