And Exemestane increases IGF-1...we could go on and on with different compounds affecting it but that's not really the topic is it?i'm new here, so I don't know if my link will come through, but there's clinical data that shows Nolva lowers IGF-1 by 25% or so.
FWIW, i used MK677 a while back, and had hoped to have hGH-like effects (losing fat, healing injuries, etc). i did not get those effects.... MK did make my dreams amazing (like a movie!) and made me hungry all the time and hold water. great for a bulk, but not when I was trying to lose weight...
When you say "I didn't get those effects": have you already injected 1.5 IUs/day of HGH for 3 months to get a point of comparison?
Everyone thinks it's going to turn you into Hulk, but HGH has far less dramatic effects on body composition than AAS.
Ibutamoren being a mere equivalent of those 1.5IUs daily, within a few months you'll probably lean out a bit, get more intramuscular water and have better skin.
It would also prevent muscle wasting if a disease makes you prone to it or if you are on a chronic negative nitrogen balance.
How long have you been on MK for? The results are not instantaneous.
