Evolutionary.org Underground #56 - Anavar sublingual Preworkout with Geneza Pharma https://www.evolutionary.org/evolutionary-org-underground-56-anavar-sublingual-preworkout-with-geneza-pharma/...

What would you say are the advantages and disadvantages to using coffee vs. pre workouts? I'm currently doing a 7 week on and 2 weeks off workout program. This is because of my work schedule. Would taking the coffee on my non workout days be a good idea? Or should i stick to preworkout?
