Kisspeptin-10- Summary
- PEG-MGF (Pegylated Mechano Growth Factor) is a modified form of MGF (Mechano Growth Factor) where polyethylene glycol (PEG) chains have been attached to extend its half-life from minutes to days. Native MGF is released locally in muscle in response to mechanical stress and quickly degrades. PEGylation allows systemic administration with sustained circulation, enabling whole-body muscle repair and anabolic signaling rather than the purely local effect of native MGF.
- Kisspeptin-10 is the biologically active C-terminal decapeptide of kisspeptin, an endogenous regulator of the reproductive axis. It acts upstream of GnRH to potently stimulate LH and testosterone release, and plays a key role in sexual arousal and libido.
- Half-Life
- ~3 days (due to PEGylation)
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development

- 50–500 mcg
- Frequency
- 2–3x per week
- Once daily to every other day
- Key Benefits
- Extended half-life (~3 days) vs native MGF (minutes)
- Systemic muscle satellite cell activation via subcutaneous injection
- Promotes muscle fiber repair and hypertrophy throughout the body
- Enhanced recovery from intense training or muscle injury
- Synergistic with IGF-1 LR3 and growth hormone peptides
- Useful in sarcopenia, post-injury recovery, and athletic performance
- Single injection provides multi-day anabolic signaling
- Potently stimulates LH and testosterone
- Enhances sexual arousal and libido
- Activates HPG axis — upstream of GnRH
- May improve fertility in hypogonadotropic hypogonadism
- Increases brain activation in sexual attraction circuits
- May restore LH pulsatility in suppressed HPG axis
