Quoted:
seems like most 'powders' are geared towards gains in mass,etc....is there anything out there that supports lean muscle, but is also geared to high defintion?
First off, the definition of a thermogenic drug is to produce heat through metabolic stimulation. Cardio will burn more fat and is also healthy for your body (reduces stress, naturally increases metabolism, conditions respiratory system, etc.)
Assuming this drug does work, your weight loss plan will fail in the long term. The only way to lose weight is to intake less cals than you burn. If this drug is artificially increasing your metabolism, as soon as you stop taking it you will begin gaining weight(fat).
Gain Mass: Lift big, eat big
Lean Muscle: Lift big, do cardio, eat "normal"
You need tons of protein to gain muscle mass. Body builders work in 2 phases: gaining mass, and losing fat. When they gain mass it isn't all in muscle, so they then work to burn off the fat.
