This stuff definitely works and that is definitely bro-science. I’m not running tests in a lab but I noticed an increase in reps per exercises and the ability to lift slightly more weight almost overnight. However, creatine is no joke. I would just caution to start with smaller doeses. I only take a small amount per day and it still has a noticeable effect. It’s recommended to take 5g per day – but that can’t be right for a 150lb person and a 250lb person. Also, don’t take it on an empty stomach and, very important, make sure you drink a lot of water. If you drink a lot of coffee, you should probably up your water intake even more. If you experiment slowly, keep an eye on your water intake, and take with a full stomach, you should be fine but don’t sue me if you’re not.
