Is it my imagination, or does taking this supplement actually make the muscles fuller?
I have been taking this on and off for 6 years, and recently began to take a dosage of 4 tablets with each of my 3 primary meals daily.
My muscles felt larger, making my body fat seem less, although I believe this is the effect of the increase in muscularity and not a decrease in fat.
I know for sure I feel much more strength, especially alertness wise and energy wise than if I don't take them.
I'm assuming this is due to the B vitamins concentration, but I'd like to hear what the others have to say.

LOVE the Ultra40's. I experienced the same things that you've just stated, and never looked back. It is very much because of the demand for HIGH concentrations of B Vits for the hard training physiqe athlete. Liver's deliver (that rhymes). Also you are getting an added 2 grams of Beef Liver protein to increase your protein spectrum per meal. The more protein sources per meal, the higher the bioavailability of your meal, and the more anabolic it becomes... in not so many words.

i get that same feeling from the Mass Aminos. I tried Ultra 40 but they REALLY tore up my stomach... i just couldn't get used to them. I tolerate the Mass better and its been 2-3 weeks - and i get this great fullness feeling, i can flex (vasolidation?) so much easier and get a groovy pumped feeling.

my body is also changing...i'm lifting heavier more frequently. i've gained 5lbs...for a girl thats not easy but i'm upping my cardio as well so we'll see what happens.

awesome product.

My all time favorite Bev. supplement. If Im worried about budget in the off season and cut back on some Bev. supps. this is one thing I never delete. I've been using 40s for about 7 years and can assure you they are an effective product. The one thing I havn't heard anyone mention is the muscles get much more dense from this product. The other advantages are more energy, endurance, fullness, and can add a substatial increase to your overall protein intake at the end of the day. I chew crazy amounts of these about a week prior to competing. Great Stuff!
