IGF-1 DES- Summary
- 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.
- IGF-1 DES (also written DES(1-3)IGF-1) is a truncated form of IGF-1 missing the first three amino acids of the N-terminus. This structural change dramatically reduces its affinity for IGF binding proteins (IGFBPs), meaning a far greater fraction remains in its free, active form. IGF-1 DES is estimated to be 10x more potent than standard IGF-1 LR3 at the receptor level locally, making it particularly effective for site-specific muscle growth when injected intramuscularly.
- Half-Life
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
- ~20–30 minutes (very short — designed for local action)
- Admin Route
- SubQ, IV

- Typical Dose
- 50–500 mcg
- 20–50 mcg per injection site
- Frequency
- Once daily to every other day
- Once daily, post-workout
- Key Benefits
- 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
- Estimated 10x greater potency at the receptor vs IGF-1 LR3 locally
- Minimal IGFBP binding — nearly all active upon injection
- Highly localized muscle growth effect when injected intramuscularly
- Activates satellite cells for muscle fiber hyperplasia potential
- Synergistic with GH peptides in post-workout anabolic protocols
- Shorter half-life reduces systemic exposure vs IGF-1 LR3
- Useful for site-specific muscle development
- Side Effects
- Injection site reactions
- Temporary nausea
- Flushing
- Elevated LH/testosterone (intended effect)
- +1 more
- Hypoglycemia (most significant risk — especially post-workout)
- Localized muscle swelling at injection site
- Potential for jaw/organ growth (acromegalic effects) with prolonged high-dose use
- Carpal tunnel syndrome with high doses
