I actually have begun taking 6-oxo for the last week and a half due to an unfortunate issue with a product containing divanil.
I was not planning on taking it, but my thoughts thus far on them combined would be:
1) Holy joint soreness
2) Pretty aggressive, and sometimes a little more emotional (although emotional part could be certain situations)
3) Greater fat loss and sweating, need to drink water all day long.
4) Moderate strength increases, but I would say drying out and fat loss would be the most noticable.
And the joint pain which was terrible, but it has been resolved for the most part, (this will seem like a set-up since an AN rep started the thread LOL), but I started taking Osteo-C and it is working very well.
I have recently stopped RPM though, in order to evaluate the blue and white pills
(will post those thoughts once they are all gone)
