I train fasted
is it optimal? no. but will having some concoction during your workout of carbs and protein actually make a difference in how you look? no idea, but I doubt it
If you are at 70% of your genetic potential, diet is on point, training hard, on 3g of AAS, will sipping a little mix during a workout make even 1-2 percent difference in real world results? thats debatable
studies show. alot of things. studies show that taking 100 supplement and herb pills will make you bigger and more healthy but if you take all 100 of them will your bloodwork and muscular growth actually be better in the real world than a guy who takes zero of them? and if so, is it noticeable?
if I take every pill in gnc, on a scientific paper, I should be getting superior results than the guy who doesn't, but will I?
I get a better pump training fasted, and I feel its better for fat loss. I also do my cardio after weights, so that is fasted too. I have lost 0 inches on my arms while losing 10lb while fasted over 10 weeks, so It certainly isn't catabolic to someone on test and tren. would I have gained any inches on my arms had I not trained fasted considering im in a deficit? highly unlikely. is there a good chance my fat loss would be less? I do believe so
Now when bulking it may make a difference, but to what extent? 4% more muscle. or .001 percent more muscle?
no one can say for sure. I would try both ways. I personally believe pre-post-intra workout nutrition is a bit overrated because so many guys now days are pushing supplements. every trainer has his own line of supplements now days.
