I recently finished a cycle of Halodrol-50 from Gaspari and things went very very well. In just over a month my decline bench (my primary due to shoulders) went from 405 up to 450!
My deadlifts went from 488 to 550!
Im relatively new to the powerlifting scene (8 months or so) but Im lovin' it. My numbers are nothing big for a guy my size (6', 289lbs today) but they are still going up!
Now, as with any cycle the key will be how much of this strength Im able to keep...that will be seen in a few weeks. Either way I was very impressed and surprised with the amount of gains I got from this stuff and all this with very very few negative side-effects.
