Winstrol (stanazolol) and D-bol (methandrostenolone) are both 17-alpha-alkylated steroids. 17-alpha-alkylation is a structural alteration that allows the steroid to withstand degradation in the liver and makes them orally available. So YES, these steroids can be taken orally.

Note 1 : The efficacy of this method is equal to taking an oral winstrol or D-bol preparation. Usually this is 75-80% of the efficacy one would get when injecting. Most are willing to accept 1/5th less gains or will take 1/5th more of the product because taking it orally is still easier than daily injections

Note 2 : These products are toxic to the liver. When injected they only pass the liver once, so they are a little less toxic. When ingested, only use them for 6 weeks on end and then stay away from them for 14 weeks. This goes for all 17AA steroids.

Note 3 : Not all injectable steroids can be taken orally, only 17AA steroids (D-bol, Winstrol, Anavar, Anadrol) and 1-methylated substances (Proviron and Primobolan). Other injectables will yield only 4-6% of their injectable capacity.
