Forget this crap, really bad for you over the long term, not to mention burn out your adrenals. Take once a fortnight max if reeealy need a kick. Replace with caffeine pill/strong cup of coffee etc. Can look into Biotest Spike products also as a cleaner alternative.
Saying that, really load up on peri-workout on nutrition based workout supps Surge workout fuel, or karbolyn and essential amino type products
Forget about constant workout PRs and try a program off this site where you stay within yourself so to speak. This very good…
