Be aware that tren also greatly increases red blood cell production. An older athlete taking tren should keep a close eye on their hemocrit to make sure their blood isn't getting too thick and possibly trigger a stroke. Additionally, Tren does elevate liver enzyme levels, which can lead to liver polyps (blood buildup). I've personally seen this issue come up for friends who just loved their tren.
We talk about the common sides like insomnia and insane sweating to the point of needing to change bed sheets at night. It trashes your skin when used for too long also. Are any of these sides a good thing?
The kidney damage is debatable since there isn't enough research done to prove it one way or the other.
I hate to always be the one talking about negatives when it comes to tren but I feel somebody has to paint the entire picture for someone who may search and read this thread later. I feel it is a bad choice for any guy over the age of 40 and it becomes down right reckless for anyone 50+ to be messing with it. If you have any pre existing heart issues it becomes even more dangerous to use this.
I'm done tren bashing but I want to emphasize that yes tren is an amazing steroid but you can also get to the same place tren will take you with other steroids and HGH and that road is the safer and wiser one from the older athlete.
I've used tren many times and loved it, I won't lie. Time passed and I saw bad things happen to the guys that used it a bit too much or too often.
In the end ask yourself what real need you have to take tren. Are you doing it to get on a stage with other old guys and sweep the masters class? Maybe you are considering becoming a pro bodybuilder at age 50? I didn't think so and neither do I. So if it is just about using it to look good you have other options out there that will get you there safely.
