I ran it alone at the beginning of the year. Not my best move, that was before I joined EF and didn't no wat I was doin. I ran it at 500mcg a day and went up to 750mcg. What I will say is the stuff is strong. But the sides were quite harsh. Insomnia, lethargy in the day. The worst for me was it made me itch like mad, had to take antihistermine to stop it. But saying that as soon as you started training FUCK you did train hard. Oh and I got gyno of it, but that was because I didn't run any dos and didn't do pct.
Hope this helps.
