I don’t think it will directly reduce prostate size, it simply won’t put you at risk of enlargement like Testosterone might. If the root cause of your prostate enlargement is from Testosterone, then the only way to mitigate that would be to come off of the Testosterone, lower the dose, or find another alternative method of combatting the problem. Indirectly it could reduce prostate size I suppose because you may be able to get away with a lower dose of Test alongside RAD-140 to achieve the same anabolic benefits as a higher dose of test on its’ own that would pose a higher risk of prostate enlargement.
For most men an Anavar cycle will be best served for the cutting process or dieting phase; the phase in-which an individual is looking for a ripped physique. This is not a steroid that will serve this purpose to as strong a degree as Trenbolone or even Equipoise nor will it have the same efficiency as Winstrol and many other DHT steroids such as Masteron but it can have a positive effect that is present in a mild form. An Anavar cycle during a cutting diet phase can greatly aid in preserving lean tissue while on a calorie restricted diet as well as increase total metabolic activity; further, when lean enough it can give a physique a bit of a harder appearance. Most men who supplement with Oxandrolone for this purpose will find 50mg per day to generally be a good starting point with 80mg per day being generally safe. Yes, you can take more but much past the 100mg per day range is not going to do a lot more for you; further, as this steroid can cost at least $2 per 10mg tab and often higher an Anavar cycle for a man can get very expensive.
Ostarine isn’t very stable, and should be kept in a sealed container in a dark freezer. Quite often a grey-market shipment will be held by customs for inspection at room temperature up to 4 months, where the quality will drop. If its mixed into a liquid (without the right preservatives and anti-oxidants) it can deteriorate in 3 weeks. Often when research chemicals have volume sales its because they’re overstocked and need to get rid of their junk. (The quality of internet grade ostarine varies greatly depending on how fresh it is, or how it was prepared. Perhaps why some guys get good results and others complain why it doesn’t work.)
