NOT for me. My brother-in-law will be running his first marathon in a month or so. I ran into him at my parents' house a couple weeks ago and asked him what kind of supplements he was taking and he said only a multivitamin.
He's an awesome guy (way too good for my sister if you ask me) and I was thinking of picking him up something when I place my next order, but the question is "What?".
He's 34 and has been running steadily for about 3 years now. He was also a former collegiate mid-distance runner so he has that build (ie not super skinny). He does also do some weight training though I haven't had a chance to get too into the specifics with him as I don't see him very often.
I was thinking of possibly getting him some Surge and maybe toss in a bottle of BCAAs and Flameout.
Does anyone have any experience with this? A point in the right direction would be a huge help.
