I recently saw some information that cacao, drank twice a day in a study, produced a 200% output in stem cell production from the participants who had the real cacao. As opposed to the participants who just had a chocolate drink. I'm in my late 40s, have been training for a long time, and I'm really familiar with the way my body responds to things. I recently changed my workout to rest pause, which always brings about the pain. My cacao showed up on day one after the first workout. My body was very sore, but as we all know, day two is where I was really going to pay. I took two heaping tablespoons of cacao and added it to my protein drink that is the last thing I consume of the day. When I woke up the next day, I was not sore, like not sore at all. I told a friend who also trains. He bought some and did the same exact experiment, with the same exact result. After I was about 5 days in, I actually messaged my wife from the gym and told her that I look like I just started a cycle, and the drugs were starting to kick in. Mind you, this is taking place during a time when I'm dropped my TRT from 200 mg a week, to 150 mg per week. I have also gained a significant amount of strength. As I am aging, and fearful of injury, my sets usually consist of 15 plus rep ranges to failure. At the beginning of this experiment, I could hit 85lb, on the particular leg extension at my gym for about 15 reps. Yesterday, two weeks into this ordeal, I hit 100 lb for 23 reps. I'm not sure if this information would be beneficial for the younger lifters, but I have found it to be extremely helpful for myself. I have another friend that is about to implement this into his training, also older like myself. Will report back. By the way, this stuff is like 15 bucks for 2 lb, and it just makes your protein drink taste delicious.
