Commonly Reported Side Effects Injection site irritation : Redness, swelling, or slight bruising at subcutaneous sites Mild fatigue or lethargy : Especially when first adjusting to mitochondrial AMPK activation Hunger changes : Some users report appetite suppression, while others feel more hungry due to enhanced fat mobilization Muscle cramping : Rare, possibly due to increased fatty acid metabolism and electrolyte shifts Rare or Theoretical Risks Hypoglycemia : Very rare, but theoretically possible when combined with fasting, Clean Carbs, or insulin-sensitizing stacks Disrupted thyroid or cortisol rhythms : Only in extremely high or prolonged usage Hormonal suppression : MOTSc does not suppress testosterone or endogenous growth hormone like anabolic steroids might No significant adverse effects were observed following repeated MOTSc administration in animal models or early-phase human data. Kim et al., Cell Metabolism Safety Summary Short-term use appears safe in healthy individuals Long-term safety in humans remains under investigation Not recommended during pregnancy, adolescence, or for those with active cancers Always consult a licensed medical provider before use Legal Status and WADA Compliance of MOTSc While MOTSc is naturally produced in the body, exogenous use (via injection) places it in a restricted category for athletes and may fall into legal gray zones depending on country and purpose
