I opted for caffeine pills because one can drink only so much coffee and it has become more expensive to buy coffee powder after the pandemic. The per unit (pill) cost here is less than one fourth that of a cup of coffee and this is a 200 mg pill. (I need atleast that much per hit, the 100 mg is not potent enough for me) and delivers what it promises. It perks me up enough so that i get a good work out, gets the endorphins or the good brain chemicals going to keep the depression at bay and puts my brain in overdrive, where i need it to be, to get my work done and also helps a little with certain dysfunctions associated with old age. Caffeine in small quantities, if you don't overdo it, is good for you, but do check with your physician before you order. I did my due diligence and i find this brand to be the cheapest and the best
