I have been fascinated by this thread. Been reading it bit by bit for a couple of days. I like most lifters get pain in the shoulder and forearms. Especially after being ill with a cold or something and coming back after a couple of weeks or so. I would be very interested to see if this works for me. I have been bodybuilding for 7 months and have gained 14 pounds / a stone of weight. Just going through the cutting phase now but feeling weak because of it. From reading this thread the product seems to get rid of human weaknesses, the "feeling old" just sounds like returning to a bog standard human 
The Limitless drug comes to mind from the movie but working on the body instead of mind haa.
I will have to give it a go anyway. I'm always looking for gains so less tiredness, pain, healing etc sounds like a recipe for some great workouts.
Also would like to say to those that have taken MPS to leave a review in the actual shop as I think there is only 1 person that has done so. Wasn't until I came onto the forum and saw the reviews here that made me want to buy it!
