Somatropin (HGH)
Summary
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that declines dramatically with age. It is critical for energy metabolism, DNA repair, and sirtuin activation. IV and subcutaneous NAD+ supplementation is used in anti-aging protocols and addiction recovery programs.
Somatropin is recombinant human growth hormone (rhGH), identical in structure to the 191-amino acid pituitary-derived growth hormone. It is FDA-approved for growth hormone deficiency, short stature, and wasting conditions. Off-label, it is widely explored for body composition, anti-aging, and performance enhancement, though significant risks accompany unsupervised use.
Half-Life
Varies by route; IV provides direct cellular delivery
2-3 hours (subcutaneous); 20-30 minutes (intravenous)
Admin Route
IV, SubQ, Oral
Subcutaneous, Intramuscular (less common)
Research
Typical Dose
500–1000 mg
0.15-0.3 mg/day (adults); titrated to IGF-1 levels
Frequency
Daily for 4–10 days (loading), then monthly maintenance
Once daily
