Trenbolone is a 19-nortestosterone anabolic androgenic steroid. It lacks the carbon atom which is present in the 19th composition. It is almost similar to Nandrolone but the difference is that it offers a double bond at #9 and #11 Carbon. This allows it to bind better by slowing down
metabolism. It has a long ester meaning that it is slow acting. It is used by bodybuilders to gain strength and body mass. It does not have estrogenic effects since it does not aromatize.
