Re: Supplement advise, please
I think Luke nailed it as far as a recommendation goes.
I won't go off into a tirade about supplements and how they are marketed to us, but suffice to say over the course of 25 years of lifting/exercising, I've tried all sorts of them.
Protein powder (for convenience) and creatine are perhaps the only 2 that matter. Everything else is very likely a waste of money as long as your diet of real food is on point.
