The most common dosage of MK-677 (Ibutamoren) used in past research appears to be 25 mg per day. This dose is noted for being consistently effective at raising growth hormone (GH) levels in test subjects. Other dosages mentioned include as low as 2 mg per day in some studies, which in certain cases led to a significant increase in GH levels, whereas the highest known dose from the research cited is 50 mg per day, which also effectively increased GH levels and was well-tolerated by test subjects.
Therefore, the summary of MK-677 dosing guidelines based on the research would suggest:
●2 mg per day as the lowest known dose explored in a study.
●25 mg per day as the most common dose used in research, showing significant effectiveness.
●50 mg per day as the highest known dose from past research.
It's important to note that MK-677 is administered orally, once per day, and is most effective on an empty stomach. The research also points to the practice of taking MK-677 in cycles, with the most typical cycle being 2 to 8 weeks on, followed by 2 to 4 weeks off. However, there has been at least one long-term study lasting 18 months without cycling off.
