One of the best things you can do in the morning is delay consuming caffeine. Your first drink of the day should be water with salt and electrolytes.
I used to take acetyl L carnitine. I once read something about it increasing testosterone receptor affinity. I used to take a whole cocktail of supplements and ALCar was a staple. In my mid 40's I would say everything I was taking helped me feel pretty damn good for a "natty."
CLA, ALA, Beta-Alanine, Creatine, fish oil, D/L-Phenylalamine, L-Tyrosine, Tyramine and a few other supplements gave me a boost at a time in my life when I cut out drinking and party drugs. I quit all my vices but felt like shit. Little by little I used various supplements to give myself every advantage to overcome the feeling of coming off all recreational drugs. It was brutal. I figured it would just take a few days to start feeling better. I mean, I assumed quitting drinking and partying would make me feel great. Hahaha lololololol. Nope. I felt like wet garbage.
Anyway, whether the supplements worked , or it was placebo, or it was just a natural progression of cleaning out, I felt they did actually work. It felt like I was switching from regular to premium, from decaf to full caffeine, if you get what I mean.
