I would only use the T50 myself, and not the 100. I know that they SUPPOSEDLY fixed the problem with the T100 being Enanthate, but the fact that it was fucked up in the first place is enough for me to stay clear of the T100 altogether.
The 100mg is good for the money, but viromone is the best prop. When I used brovel, I just used about 30-40% more than usual to account for low dosing and probably lower quality......and it's so cheap.
