I am running T E and Tren E, and getting very stable levels (of course...enanthates can be injected every 4-5 days w/ stable levels). Ran Test/Mast/Var for 6 weeks, and then switched to test/tren. I lost a lot of fat on the Mast stack, but gained only about 5-6 % in strength. Total mgs per week were about 800.
I am running 600mg test e a week and a touch less than 300 tren. W Letrozol (only .6 mg eod) and 10 mg Tamox on the days I don't used Letro.
After a week my strength is going through the roof, I am up 6 lbs (maybe in part due to water from test....although Letro and Tamox should control that). We have a seated chest pad row machine at my gym, and I am getting at least 10 reps w/ 5 45 lb plates on each end. The most I have seen anyone else do is 4 on each end, and that guy had 25 lbs on me (I weigh 225). I love training these kids into the ground, especially since I am an old man (50). OK, sorry, enough bragging[

Had one night of sweats and a bit of insomnia, but have been fine the rest of the week. Regular cardio (80% MHR for 30 minutes 3 days a week) has been fine, maybe a bit more huffing and puffing. However when I hit the bags (very high intensity....90% plus MHR) I am really dying to finish 20 minutes. Nonetheless, overall I think the strength/muscle gains are worth it. Just going to suck it up and be tough in regards to the cardio
