I've run tren ace twice at right around a gram per week. Just had increased body heat and slight insomnia. Positive sides far outweighed negative. Crazy sex drive, strength through the roof, much more aesthetically pleasing, awesome gym aggression, did I mention ridiculous sex drive? I had no negative sides up to 700mg/wk, none. I have a high tolerance to everything unfortunately, so it's a double edged sword. Slightly better results with tolerable sides, but much more expensive. Biochemical individuality folks, to each their own.
