ipamorelin vs mk-677 MK-677: Which GH Secretagogue Wins? is mk677 ipamorelin MK-677 (Ibutamoren):

Beware of products with extremely high doses (may indicate poor absorption) and very low doses (under 100mg) unless in highly bioavailable forms

However, these models struggle with capturing long-range dependencies in text [82]

In recreational athletes, supraphysiological GH doses are often used either alone or in combination with other doping substances (140), and studies have shown that GH improves anaerobic sprint capacity, but not strength and endurance (141), and increases GH, IGF-I and fasting insulin levels (142, 143) mimicking those seen in acromegaly patients ( Table 1 )

Clearly, this is an important issue that warrants additional research to determine if muscle cell lines that are maintained at high oxygen tensions develop phenotypes that influence experimental outcomes
