yep, i have and lots of guys to until the water from the anadrol spills over subq, but yeah in the beginning of anadrol when the muscles are super saturated with water, hell yeah i get vascular , its a fine line though cause at some point it spills and smooths ya over, which is why some guys play with it a lot pre contest a few separate times to see how long it is until the spill/smooth over, so they know how to run anadarol right before stepping on stage, I personally have not used it pre contest, but plenty of guys have and thats how they do it! Its best to keep a journal of exact doses, and hour of day you took it, and exact what and how much you ate and drank, and you should THEORETICALLY know how to manipulate it so you can run it pre contest and step on stage full as fuck , vascular and not smoothed over yet!
But again, i never had the balls to try , as if you fuck up a day or two out, their aint shit you can do and all that hard work is for nothing and your ass is stepping on stage smooth and fucked up looking, but i guess if you do a few runs and if you think you have it down properly, and know your body then go for it!
