Does anyone believe it's worth the extra money?
I just started doing some research but it is sparse.
I read when Cardarine was banned in Australia, this was the replacement because it was not banned. Same/similar pathways.
One study showing a great increase in exercise capacity in both trained and untrained athletes, a study looking at it being a exercise replacement pill. In fact, what I read was an article mentioning the study, not the study itself.
For a comparison of how well 0742 works compared to 501516, I think we'll be reviewing user logs of people who have used both. There is a viable log of GW501516 going on right now in this forum. I think he'd be the logical choice to do a comparison. Well-documented and trustworthy (IMO).
I have not come across a study (yet) putting 0742 in the same bucket with 501516 with regards to a focus on cancer.
If a similar cancer study does not exist, and the pathways are similar, I would change my marketing to "safer" than Cardarine instead of "stronger". Then again, not all research studies become published articles.
