i use the 10 mgr Chinese yellow ones
since about 2 weeks. First at 50 mgr/day, right now on 80 mgr/day and they sure work.
One must look at Ox like this. Right now, no one really knows what the perfect dose is.
Some (as states) take 7.5 mgr/day and have great gains, other are taking 50-100 mgr. Can well be that 25 or 30 mgr/day will give the same result as 80 mgr/day. Or maybe the BTG's are the very best, but then again not everyone can have them.
Also this depends on the person. Anyway i will take it up to 100 mgr/day and then to 120 mgr/day to see the effect.
