My advice, for what it is worth,
stay with the short acting ACE version. Tren is not a substance you want to have building up in your system over a prolonged time. This in regards to side effects and pct. Stay with ACE as it is way more managable regarding side effects and pct. Tren E is deceptive in this way.
If you do take the E route, watch your BP etc. And get regular bloodwork done, it is killer on the kidneys. And last but not least, recovery from tren is really hard. Most people will take a full year to recover or more. Some people never get their own hormone production started again and will be depended on replacement therapy for life.
Tren has sweet effects, but they can be acquired with other drugs, which don't have the negative long lasting effects.
