I think if it's size and strength you require,you'd be better to run a size and strength stack,not Winstrol,T3 and
Clen.That's a combo that one would cut with.
Get rid of the using T3 idea completely if you want to make gains in size and strength.
With a 17aa steroid as winstrol you'd want to run it no longer than 6 weeks at 20-50mg to be safe,it has an active half life of 8 hours so doses would optimally be administered at even intervals.
Let me just say that oral only cycles are daft,you're only getting half the anabolic benefit of a more consistent stack with an injectable.Gains will be disappointing as you'll be limited in cycle duration due to the liver toxicity issues.
Could you eleaborate on why you dont want to use IM method,which is safer and more effective?
