definitely the winstrol - you should experiment with dosing. Start low like 25 mg per day or less, and see what gives you results.
I would be very guarded against using the compound for any longer than three weeks at a time however.
Btw what does your week of track workouts look like?
In University I actually had a track coach who ran for the Mazda track team out of Toronto with Ben back in the day - This was more than 10 years ago
Fack were the workout grueling.
And I didn't have any juice, or massage therapy to work with.
