MOTS-c vs Human Growth Hormone (HGH)

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

MOTS-c

MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide that plays a key role in metabolic regulation and has emerged as a significant longevity research target.

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

AspectMOTS-cHuman Growth Hormone (HGH)
MechanismActivates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis.Binds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues.
Typical DosageResearch protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established.Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher.
AdministrationSubcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation.Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated.
Side EffectsLimited human data. Animal studies show good tolerability. May affect energy levels and exercise performance.Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses.
