The first isolation and structure identifications of prednisone and prednisolone were done in 1950 by Arthur Nobile .    The first commercially feasible synthesis of prednisone was carried out in 1955 in the laboratories of Schering Corporation, which later became Schering-Plough Corporation , by Arthur Nobile and coworkers.  They discovered that cortisone could be microbiologically oxidized to prednisone by the bacterium Corynebacterium simplex. The same process was used to prepare prednisolone from hydrocortisone . 
presents you another cutting cycle for summer which will make you look hard and solid. As a base we will use testosterone enanthate however you may replace it with testosterone propionate as in some individuals enanthate will make visible water retention but I dont think this is a problem as you dont prepare for the contest, right? 🙂 On the other hand switching to propionate will bring you another headache as you will have to inject it EOD plus you will inject Primobolan ( Methenolone Enanthate) 2-3 times per week so having to inject primo and test propionate will keep you really busy and will not give your injection sites enough time to rest.
Oxandrolone is very popular, and put into many cycles where the user can afford it, and is popular in stacks with drugs such as testosterone as well as with with high anabolic/moderate androgenic steroids such as Equipoise or Nandrolones. For the pre-contest bodybuilder, oxandrolone is often used in conjunction with Masteron or Trenbolone, and Testosterone Propionate as well as injectable Winstrol. Women often achieve incredible results from 5-10mgs/day of oxandrolone alone. Anavar – Oxandrolone – 100 tabs – 10mg each
