It's great stuff,
Im ussing it now in my cycle 100 mg/eod, whit 500 mg sust ew.
But 1 thing i now for sure, it isn't working in 1 or 2 weeks effectively. I'm now in my 4e week and it's doing his work great. Less water retention, nice rounded musscles.
And I havn't any problems with hairloss, but this is personal, so you could use finasteride like avago say.

good luck
