HGH

Human Growth Hormone (Somatropin)

Human Growth Hormone (HGH), also known as somatropin when manufactured recombinantly, is a critical anabolic hormone that stimulates growth, cellular regeneration, and metabolism. FDA-approved for growth hormone deficiency in children and adults, Turner syndrome, and other growth disorders. HGH promotes lean muscle mass, reduces body fat, improves bone density, and enhances overall quality of life through its primary mediator, insulin-like growth factor-1 (IGF-1).

Dosing Guidelines

Research Protocol

Adult dosing begins at 0.15-0.3 mg daily, with monthly titration based on IGF-1 levels and clinical response. Typical maintenance ranges from 0.4-0.8 mg daily, with maximum doses up to 1.0 mg daily in some patients. Pediatric dosing is weight-based at 0.025-0.05 mg/kg/day (0.18-0.35 mg/kg/week). All dosing should target IGF-1 levels in the upper normal range for age. Evening administration is preferred to mimic natural circadian GH secretion patterns.

Simple Explanation

For adults, everyone starts low (about 0.2-0.3 mg daily) and increases slowly over several months. Your doctor will check your IGF-1 blood levels monthly and adjust the dose until you're in the optimal range - usually ending up at 0.4-0.8 mg per day. Children get doses based on their weight. The key is starting low and going slow to minimize side effects while finding your perfect dose.

Mixing & Injection

Technical Instructions

Subcutaneous injection using insulin syringes or pre-filled pen devices. Common injection sites include abdomen (preferred), anterior thigh, deltoid, or lateral thigh. Rotate injection sites daily to prevent lipodystrophy. Evening injection (6-8 PM) is optimal to align with natural circadian rhythms. After reconstitution, use within 14-28 days when refrigerated. Allow medication to reach room temperature before injection.
