Human Growth Hormone (HGH) vs Dihexa

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Human Growth Hormone (HGH)

Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.

Side-by-Side Comparison

AspectHuman Growth Hormone (HGH)Dihexa
MechanismBinds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues.Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway.
Typical DosageMedical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher.Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency.
AdministrationSubcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated.Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically.
Side EffectsJoint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses.Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes.
