Tren can diminish your cardiovascular endurance. Not a good recommendation for speed. Winny is the answer here. It elevates nitrogen retention even with calorie restriction. And yes, it directly burns fat as a result of raising the body temerature. I don't know why people still don't understand this well known and visually obvious fact. Winstrol burns fat, period. Even better if you eat clean.
The true problem with winny is it can compromise the overal tensile stregth of your tendons, so a tear is much more likely. A small dose of Deca is the answer there.
Anavar is also a great choice here. Personally I would use the anavar, even though I think it is slightly less effective mg for mg. The sides are less severe.
Stay away from test, D-bol, tren, EQ, etc. Use winny or var.
One other thing comes to mind now that I think about it. Depending on your overall health and the length you are gonna run this, halotestin might be worth considering. Just don't mix it with any other 17aa, and don't take it longer than a month.
