Just wanted to pass this on to folks who may be trying to decide to buy MASS PRO SYNTHAGEN. I am a weight ifter in my 40s. Recovery is of the utmost importance. I went out on the limb and purchased some MASS PRO SYNTHAGEN to try and see if the supplement lives up to all the hype. Here is what has happened so far. I will use the term "Extend Effort Ability". I can tell a big difference in the ability to up my work capacity in the gym and in strongman event training. I am breaking PRs more frequently than before. The handling the higher volume has increased my DOMS greatly but the plus side to this is that my recovery from it is quicker than before using MASS PRO SYNTHAGEN. I just want to thank Rob for creating such a awesome supplement. I understand there are even greater things to come.
