i've ran letrozole before just could not get my hand on it this time around. So i decide to use the nolva since that works for me well too. I have extensive access to hcg since one of my best friend is a doctor who owns a weight loss clinic. I think hcg is about top dog in my opinion for during and post cycle to keep the nuts in check. Like i said have had no problems thus far and this is my life so i see no reason why not to try and improve. i have already reach my natural max or so i was told by a competition trainer 2 years ago. so i see no reason why i should not run low dose cycles to try and improve myself beyond these limitations?
