The problem with Var is making sure of its purity. Get a little dbol in there and things can side effect real quick!
At one time I had a very good quality Var that I took for 6 weeks while in prep to compete in figure. Holy cow, did it enhance!
If the diet is not basically 95% perfect...think of a prep diet, an anabolic can make a woman look bulky, as if in a build phase.
Think about the look that you want. If you want a slimmer or leaner look, the first priority is diet. Everybody says it, and that's because it's gospel.
Nothing changes without the diet, which accounts for 85-90% of your success. That has been a hard thing for me to accept over the years. I try to out train cheats, and the look isn't what I want.
Anywho, Clen will work, but can make you feel like doo-doo. If you've never taken an OTC fat burner, you could start there, and go with a ramp up of Clen every 2 weeks. I have taken Clen before, but can't seem to make myself doing it again because I felt so crummy.
My greatest advice is to seek out a well respected nutrition coach, one who works with prep clients to compete. Make sure you really research, and have a conversation to identify if personalities align and all that jazz. If you've done that already, then either re-evaluate who you're working with or commit fully if you haven't already.
Diet is 85-90 % of it. Hard reality of a fitchick. LOL
