the main trade mark for OT is hardness...U can run it with anything really..But its really best ran with winstrol ,test prop and primo and with some fat burners such as clen,albuterol or ephedrine.Anything around 60 to 100mgs is about what u need to really feel the full effect.....And just like most steroids u will gain strenght...No gyno reported on my end..and in fact,androgenic activity is so slight it doesnt even register.and ive done alot of OT in my history to know this fact as true also,one great thing about OT is that most muscle u build from it is retainable.......What makes OT a class A steroid too is that the more u take the better the result in fact compared to d-bol in a milligram to milligram it can actually surpass d-bol by five times in actual blood testosterone concentration.....not like most steroids to where u level out once u get so high in mgs mostly d-bol....some histroy about OT it was developed in the 60s in east germany and was used extensively during the 60s and 70s within the olmpian community of athletes..dw
