I will agree with this explanation from my experiences.
I started using AAS entirely too young. I was 22 when I started my first cycle. Now, don’t get me wrong. I’m a nerd, I love chemistry, and I love to know how and why things work. So I definitely did my research, figured out the “so what” of running a cycle, and what ancillaries and support supplements to use while on cycle. BUT, that didn’t stop me from making stupid, rookie mistakes. I eventually used way too much gear per week (over 1 gram of total AAS), and used compounds far beyond my experience level/body maturity.
I have used Tren around 12 times, that’s an estimation. I will echo Wes’s words on it works fast, and the results are spectacular. But while those things are true, I will also say as I got older, the golden beast started affecting me WAY differently from the mental/emotional perspective. Mood swings, emotions all over the damned place, borderline bipolar tendencies, and an inability to realize what the Hell was wrong with me until I woke up to the fact that my body simply can’t handle Tren anymore, no matter the dose/ester. I envy people who can take it without issues. I definitely cannot.
