Unlike most other Amino acid pills....aka.....HORSE PILLS.

These are easy to swallow and they dont stink like other brands.

And all you need is four (4) with every main meal of the day (BREAKFAST/LUNCH/DINNER)

I also add four (4) before and four (4) after i train and that works for me.

You'll surely see an improvment in size/definition and strenght...just make sure you maintain a proper and health diet.

Remember...THERE IS NO MIRICLE PILL ! 5 stars

Not a bad product at all...helps your muscles develop more rapidly after exercise. The only problem is the amount of tablets that have to be taken...Its a bit much. 4 stars

I'm a weight lifting newbie and my boyfriend who's ex-marine told me that he used to spend all his money buying smokes and amino acid/creatine on the ship(he was 200 lbs w/ 4% body fat), so I decided to give it a try.
I've been lifting weights for about 3 weeks now (3-4 times a week, 45 minute each session) and my weight hasn't changed much (mabye a couple pounds down) but I can already see the definition in my arms, back, and legs. I'm looking forward to my weight lifting session instead of dreading it because of the amino fuel. It really gives the boost and energy, and your muscles feel tingly instead of sore the next day. I only took twice a day instead of three times a day (4 pills after breakfast and another 4 after dinner).
The bottle only lasted about 7-10 days, so it's not cheap (I let my boyfriend take some with me) but I am convinced enough to buy more. I'd rather spend money on products like this than some diet pills out there. I agree with the other reviewers about the pills being too big (about twice as big as your normal multi vitamin), and I had it stuck in my throat once but you get used to it.
Plus after you see the result and knows that it works, big sized pills really didn't bother me.
I'm thinking about sending my testimonials to Twinlab with my before and after photos in about 6 months :-)
Well, I guess this review was more useful to females who are interested in building some muscle mass and definition like I do, not for the weight lifting experts. haha. 5 stars

These pills are huge. I never have problems taking pills, but these are tough. They are about twice the size of my Centrum multi-vitamin. I found that it's best to eat something first, then take these. As for benefits, the drinks may be more effective. 3 stars

I've been lifting for about 8 years now and I'm 6'1, about 240 lbs with 18'' arms and a 49'' chest. I'm telling you this as I've gotten to the point where I've plateaued in my lifting and I was looking for a way to get beyond the plateau. With that out of the way, I'm not sold on this product at all and I didn't notice any change what so ever when taking these pills. So after taking them for about two months, my conclusion is they do not work for me. Also, pretty much all the amino acids in these pills are available in most protein shakes and the protein shakes offer more in the way of protein. 2 stars
