What is Ibutamoren?
MK-677, commonly known as Ibutamoren, is often grouped in with SARMs, but technically is not. It is an HGH secretagogue, which means it promotes the natural production of HGH and IGF-1 in the body. This makes it a highly valued compound for bodybuilders and athletes as these hormones (IGF-1 and HGH) benefits, specifically the potential for muscle growth, are well-known. In addition to muscle growth, users can expect other significant benefits from MK-677 such as recovery, brain function, and sleep quality. It has also been shown to be useful for the repair of tendons and connective tissues, and for this reason, is often paired with SARMs and anabolic steroids specifically designed for muscle and strength boosting abilities (think Ligandrol, Testolone, Dbol, Anadrol, etc.).
Ibutamoren was originally developed as a possible hormone replacement therapy drug, and there has been clear scientific evidence that its use results in an increase in the production and release of IGF-1 and GH, and maintaining these increases without any anabolic side effects. Ibutamoren will not affect natural testosterone production, and therefore, will not require supplementation with Testosterone or require a PCT after use.
What is the recommended dosage?
Ibutamoren is safe for both male and female use. Most users find a lower dose of Ibutamoren suitable when adding to other stacks. Typically, doses in the 10-30mg/day range work well, but more experienced users have been known to use up to 50mg/day. Whatever dose you decide on, a common cycle length is between 8-12 weeks, followed by 8-12 weeks for recovery.
Although MK-677 has a half-life of 24 hours, higher doses of more than 20mg are commonly split into two smaller doses per day to reduce the risk of fatigue and other potential side effects.
Recommended Dosage (Male and Female): 10-30mg/day
Ideal Cycle Length (Male and Female): 8-12 weeks
What Does Ibutamoren Stack Well With?
MK-677 can be a welcomed addition to almost any anabolic or SARM stack due to its ability to increase natural IGF-1 and GH in the body. You will find this compound to be synergistic with most compounds.
It is not uncommon for users who wish to avoid anabolic steroids to use a SARM-only stack such as:
SARM-only Cutting Cycle: Cardarine, and Testolone (RAD-140) will be a potent fat-burning combination with enhanced endurance. If Testolone is used, a PCT is suggested as Testolone can suppress natural testosterone production.
