I've read feedback from various individuals who have used them (several years ago ~ kind of hazy now)and I reached a neutral position but I'm not opposed to giving anything a try if individuals have had noticeable results. Have you used it and what were the b/f and after results, if any.
If you don't mind, could you let me know what the differences are?
One of the things that prevented me was the variety of choices (if I'm remembering correctly)and I was researching and experimenting with supplements at the time and it was overkill.
