Sustanon stays in your system for 7 weeks?! Then why do you start pct two weeks after your last shot then? If so then yes 23 weeks would be way to long. I would hate to cut it short though as that would mean I would have to cut my tren cycle short and it's the enth version so I'm on the fence. I'm half way into my 3rd week on 300mg and really haven't seen much in terms of body fat loss. My body weight is steadily going up even though I'm on a cut of about 2500 calories. Sitting at 234lbs right now. No sides yet. I was really worried about the insomnia part as I work long hours but haven't had any problems yet.
