Im a meat head on a budget so heres my rationale behind my suggestion lol I'd defintely reserve for preWO only for that extra boost... I'd say see how well you respond starting low at 25, and working up to 100, 25 at a time, that way if you can get away with just 50/75, or even only 25 works well, then that just one bottle will stretch on just that little bit longer...LOL
