Seems like a lot of talk about fakes or extremely impure products.
Any one have any info on how S4 effects the liver? Sure would like to read some liver value data.
There are still some things that haven't been cleared. First of all, it seems that Ostarine is not identical with S-4. They are very similar stuffs, but not the same.
S-4 is Andarine, and Ostarine is MK-2866.
A certain person also claimed that Andarine/S-4 was discontinued because of clinical toxicity. However, I couldn't find any sources of this statement. One review says that Andarine was discontinued simply because of the development of Ostarine, which seemed to be a better SARM of a new generation.
