Protein- no explanation there.
BCAA's- especially post-w/o recovery. As T noted, most quality protein has BCAA's. I use Afterglow anyway. If you also engage in high cardio some people like to use intraworkout.
Glutamine, Leucine- Worthwhile investment.
Multivitamin (good one, made from whole foods), fish oil- Definitely.
Everything else is optional, imo. You can use N.O., it's a kickass vasodilator and helps somewhat with stamina, especially cardio. Karbolyn, once again, very optional and I only use for heavy cardio work, but it does work.Ceatine, which a cell volumizer and needs sugar to assimilate, imo, is kinda' worthless if you're using gear, and we all are. 8) Most protein nowadays contains creatine anyway. Herbs such as Saw Palmetto, etc., should be used on a definite needs basis. A lot of herbal supplements are gtg, but should be used, as noted, on a need-to basis, imo.
We're living in the 'Golden Age' of supplements, there's a ton of legit, gtg products out there, you just have to wade through the research, reviews, etc., to realize what you feel you definitely need and then choose a worthwhile product. That being said, there's a ton of crap out there also. Certain companies, like Force Factor, Muscletech ( and these are just 2) produce junk,IMO. Remember, the supplement industry is a multibillion$ industry, lots of room for bogus claims and products in there.
Maybe we should start a review thread on supplements, everyone can review products by profile, efficacy, taste, cost, etc., on a scale of 1 to 10.That way we could get some solid reviews inhouse, without having to rely on company propoganda and guesswork. Everyone's body chemistry is unique. What works for me might not work so well for you, and vice versa. It's really experimentation on an individual basis to see what works for you.But we can help eachother with honest opinions and reviews.
