Taking the growth hormone secretagogues in the evening means it shouldn't cause any issues. Adding it seems like a solid choice. There's no real concern unless cancer is a factor for you. I personally struggle to get up in the morning without MOTS-C following the GH pulses, so everything should be fine.
I've been using reta for three months now, beginning at 2 mg and gradually increasing to my current 6 mg dose. About two weeks back I started including mots-c at 1 mg each day I exercise, which happens four or five times weekly. Things have gone well, and I'm considering adding a cjc/ipa mix soon. Do you think I should wait longer before introducing that?
