after searching and reading i found out the best peptides and steroid products for athletic runner and sprinters are these ( GW501516, TB500, PEG MGF and winstrol ).

My questions are:
1) can i make a combo of these products ??
2) which protocol ( cycle ) is the best for us to use them ??
3) are they dangerous ??
4) If u dont advice me to take these products , which products u advice me to take to reach my edge of sprinting and running ??
