Yeah, maybe it's a water thing. I've heard people with joint pain should avoid caffeine, that why I made the connection. It started acting up on me last week when I was playing Negro-ball. I've started taking Glucosamine and Chondroitin, it seems to be getting a little better. I did deads today, but no squats.
I've heard that the aspirin isn't really necessary in the ECA stack, and I didn't like the idea of taking 3 aspirins a day for no reason.
BTW, I've been running the ECA for just over a month now with great results.
Someone will probably say I should cycle it, but I've done serious reading on the subject, and I know that it's not necessary. The fat burning effects actually increase over time, whereas the energy boosts and anorectic effects fade away.
