I think it does help me with weight-lifting. Could be just an effect of imagination or suggestion. Anyway, it can't hurt. I take a dose an hour before lifting.
The idea is that it can help you somewhat over-stress muscle. That's a good thing, because a goal of weights is to micro-damage muscle and then let it repair in better condition. I tend to work towards muscle-failure, or close. I wish I could say that I like it, but I do not. I'd rather read a book.
Why do I do heavy weights twice weekly? To try to avoid sarcopenia and osteoporosis. Plus to be appealing to my wife. Three times might be better, but I spend times on calisthenics too.
