I ran it from April thru sometime in September....ugh, this was around 2002 IIRC. I was in college, and was going through a tough time not only from college stress, but from a bad relationship. I wasn't in great shape from being so busy in school, and hadn't trained for a few months. I couldn't wait until summer to start training, but started early to get in shape and raise my self-esteem. So around April, I jumped back on the train with everything, and got in great shape. Tren makes everything easier, but I have to say that the only sides I have received from tren was some slight insomnia and night sweats the first few weeks of use, and eventually nipple sensitivity. I can't use it anymore....though i'll probably try again, because of the nipple sensitivity it gives me. I had gyno surgery in 2007.
Seriously, for the longest time, I could run any dose of Tren I wanted and was fine until the gyno part caught up to me
To answer your question more directly though, my labs came out fine, except for lowered HDL values.
I got blood work all the time at the college health center, multiple times per year. I was also taking test prop/winny and some T3 during some of that run. I quit that cycle about the 1st or second week of september because my schooling had started back up, but I had blood work done when I got back to see where my values were, and then again at the beginning of November about 6 weeks later. My HDL was lowered some in the first, and then normal by that November.
I jumped back on Test at the beginning of that December, and then a few weeks later jumped on Tren at a dosage of 150mg/d for about a month just to see how it effected me at that dosage. I ran out around 5 weeks in. This was during my winter break. I stayed on some test for the better part of that spring semester (my graduating semester) even though I didn't train much.
It was cool seeing and learning how I reacted to everything.....but if I had to do it all over again, i'd have just stayed off AAS while in college. It's too hard to worry about gaining size and being "hardcore" while jamming out biochem courses, and commuting 3 hours per day....along with everything else. Now I just recommend staying "in shape" while in school, and not worry about the whole BB'ing part that we all love.....it's not going anywhere once we/somebody is done. I mean, train when you can, but if you have a test coming up, and are worried about training, you really need to get your head on straight.....different topic altogether
Then again, we're all addicted to the gym...at least I am...lol. We live and learn
