Ok, I started taking the directed dose of the Trifecta stack.. Two pills of MD1 with breakfast, two with dinner... One of the Methyl Masterdrol V2 with breakfst, one with lunch and one with dinner. As of last night I'm having a pain in my left hand side/rear. Looking at the human anatomy and from what I hear from these types of supplements is that it does damage to the liver.
What exactly is going on? What damage?

This morning at the gym it was really becoming a 6 on the pain scale and I'm considering stopping my intake of the products.

Any direction to articles, threads etc would help me make an intelligent decision... Common sense says to stop.
