I was looking at Thai-25 and then found this site. I did some other research and thought to myself, "I'm going to put on 15 lbs of muscle in a week?" Here's what my research has discovered. I'm not an expert on this subject but I'm no fool either. To maintain my weight of 175 lbs, 6 feet tall, I need to eat 2625 calories.
First, the step in adding just ONE POUND of muscle I've read I need to add 1,000 to 3,500 calories to my daily diet. So let's pick a figure in the middle, 2,000 calories. That means that I must daily ingest 4,625 calories. Whoa!
Next, I have to convert those calories to muscle, otherwise those calories will turn to fat and I'll gain a pound of fat each day. (Don't believe me? Go in the hospital for an operation and lay in bed for a week. Your daily maintenance requirements dip tremendously but they feed you calorie laden fluids and you check off these great items on your menu for tomorrow. You WILL come out of the hospital much heavier if you don't burn all those calories beyond your maintenance requirements.)
So you've got 2,000 calories each day that you need to do something with. You can do aerobic exercises (a lot) and maintain your weight or reduce it by burning 2000+ calories. In this case you don't gain muscle, but you do maintain your weight.
Or you can do anerobic exercises (weight lifting) to burn those calories. That's a really INTENSE daily workout to convert those calories to muscle (and there will be fat in that muscle.) REALLY INTENSE. You can even build more muscle by adding to that really intense workout and burn some of your maintenance calories, not only slimming down but building additional muscle tissues. You could also combine an aerobic/anerobic exercise daily to build muscle, endurance and reduce the amount of fat you produce.
But that's a lot of calories to take in so you better make real sure all of your exercises add up to those extra calories. Otherwise you're adding fat.
Do you need a supplement for that? Not really if you are focused. All I read is that Thai 25 makes you want to exercise more. That's a psychological thing...it doesn't motivate you. You're falling for the hype.
There's one simple rule when it comes to this issue. If you eat more than you burn, you gain fat. The same is true in reverse. So you need to use those extra calories and you either slim down or maintain your weight or you make really sure that you convert all of those extra daily calories to muscle by INTENSE exercise. Otherwise, you're just going to get fat.
There's only one way a supplement produces muscle and we all know what that is.
If somebody thinks they can convince me otherwise, let me know.
