I have used it, but I was 17-19 at the time in the late 80s. For all practical purposes it is Primo. It is not a non methylated oxymetholone, this was a common misconception b/c supposedly Syntex introduced it as alternative therapy to Anadrol to decrease androgenic sides. Of course it is attached to acetate so in effect it is actually identical for all practical purposes to Primo acetate. I believe they differ only by the addition of a methyl group to methenolone to create stenbolone. I have used primo acetate as well, but those came in 20mg amps and could be quite painful. I believe the addition of the methyl group makes stenbolone more soluble as it was available in 100 mg amps. I also believe the 1 methyl (Primo) makes for some increased oral bioavailability, but other than that I think the additional methyl group has no different pharmacolgic effect. So methenolone acetate is better for oral use, stenbolone acetate or methenolone enanthate for injectable use.
I used 100mg qod, top end dosing would be 100mg qd. There should minimal to no sides, same as would apply to Primo in those areas.
