From what I've seen... (a number of guys at my gym) Tren has given them fewer sides than some
other substances such as
Superdrol or
Phera-Plex. No back pumps, lethargy and minimal acne. I have a bottle of
Havoc but may go this route because I had a bad experience with
Phera-Plex back in 06'. The lethargy and back pumps were so bad, I couldn't believe people are popping this shit left and right on these forums. I gave my bottle to my bro and said, "Good Luck".
