I realize that this is a laughably low dosed cycle for many of you, but I am running it as a cutter and just wanted to avoid catabolism. I blow up on gear anyway and even at these doses I am gaining weight while losing fat and my cals are so low I feel like I am starving (about 3000/day). Anyways... 25 yrs old 6'5", 250ish lbs, about 12% BF and dropping 100mg tren E/ 4 days 250mg Test E/ 4 days 30mg Tbol/day .5mg Femara eod. This is end of fifth wk and I am now discontinuing the Tbol. Anyway- I have been getting totally short of breath if I do intense cardio and I've been having to rest for some time between sets to catch my breath. This is the first time I have ever used Tren and even at this super low dose I have been getting night sweats. Has anyone else experienced shortness of breath while on Tren? The results have been incredible though. I have not had hypertension, just checked it yesterday at work.
