Ibutamoren MK-677 Magnus 60cap/25mg

MK 677 (Ibutamoren)

This is a non-peptidic, orally active and selective agonist of the growth hormone secretagogue (secretion-boosting) receptor. It mimics the action of ghrelin (the hormone that regulates appetite and the distribution and rate of use of energy) in the stomach, raising growth hormone and IGF-1 levels, but does not affect cortisol levels.

MK 677 Benefits

Human studies have shown it to increase both muscle mass and bone mineral density. Dosed at 25mg daily, Ibutamoren has been shown to increase IGF-1 levels by 60% in 6 weeks in humans. A 72% increase in IGF-1 levels was seen after 12 months.

Ibutamoren is non-hormonal and therefore requires no PCT after the cycle is over. It is best utilised in at least a 3 month cycle with dosage increasing each month. The optimal dosing time for MK 677 is at night directly before going to bed. You should start to notice a deeper sleep almost immediately. If you should wake up with numb or tingly hands, do not worry. This is a common side effect of the extra GH in the system.

MK 677 Side Effects

  • Increased hunger
  • Lethargy
  • Impaired insulin sensitivity
  • Water retention

MK 677 Half Life

The half life of MK 677 is around 24 hours. This means you can take once per day if you wish. Those who take it to increase appetite might take in a morning, but if it makes you lethargic, you might want to take before bed.
