HGH (Somatropin)
Also known as Human Growth Hormone, Somatropin, rhGH, Genotropin, Norditropin
Recombinant human growth hormone, identical to the GH your pituitary makes. It is the actual hormone that every GH secretagogue (CJC-1295, Ipamorelin, Sermorelin) tries to stimulate. Prescribed for growth hormone deficiency; used off-label in anti-aging and performance for body composition, recovery, sleep, and skin quality.
How it works
Binds growth hormone receptors in the liver and peripheral tissues, driving hepatic IGF-1 production and activating JAK/STAT signaling. Promotes lipolysis, protein synthesis, and cell growth.
Benefits

- Reduces body fat, especially visceral fat
- Improves recovery and tissue healing
- Deepens sleep quality
- Improves skin elasticity and collagen
- Supports bone density
