I feel it works well. i am using it for cutting now, and i am not losing any muscle. matter of fact i am gaining a bit, and losing fat at the same time. of course keeping protein intake high and eating properly. i use 50MG clomid ED, and/or 1/2mg arimidex EOD. Plus i take saw palmetto extract twice a day (i really feel this helps with hair loss, even though it may interfere somewhat with the mag-10 effectiveness). This way i can take one dose of mag-10 a day for longer periods. say 8 weeks. Biotest got some pretty good stuff, i am starting on MD6 right now as well as surge. they do censor the hell out of T-mag online though. you can't say anything on there anymore. sheesh.
