All supplements are just that , and help Very Minutely. Unless however ,your deficient.
I have done most everything through my Life , and my own conclusion was when I was 36 yrs old and hit personal bests ,Naturally supplmt-free .Just Food and Protein Drinks.
Carbs are necessary for energy . But I avoid them 3 hours prior to bed. Anything ingested upon going to bed, needs to digest very easily. Yogurt , Pure Protein Shake.
Fruit at bedtime to a very minimum. Cause its a carb.
Pasta and breads to a minimum period. BUT , I have found personally , Lasagna 2 1/2 hrs prior to a heavy workout (chest/tri's) = Awesome Pump !!!
Balance in all things right.?
Carbs equal my protein for Breakfast and Lunch. Dinner is 90% protein. I have ample energy throughout the Day. And Sleep good.
The stimulant... I'll admit I use muscle techs neuro core ,only since I turned 42.
If you need it ,gauge it so you don't lose Sleep. Cause Sleep is the other 33.3% of Workin Out .
I take Gold Standard's whey protein too, thats it. Don't spend $ on Supplements . That money is better spent on a meal that is tailored to the results of your hard work and discipline. Honestly , Creatine is the only supplement that has a proven result. Water retention.
I did twice a week workouts in my 20s and 30s. In my 40s , once a week. I guess this is where age starts to hit Ya.
Those ads for supplements , are Brainstormed and Think-Tanked to death, by very damn smart people who find an avenue in which to lure you to buy their EMPTY promise, so they can make a ridiculous paycheck. Take it from somebody that wasted several hundred a month on supplements ,following appropriate guidelines for improvements by different companies selling powdered nothing, many times over.
