If healing your joints and bones is all you want to achieve, deca is definitely not the best choice. There is no doubt that it will reduce the inflammation and decrease pain. However, it will not actually heal the joints. As a result, you can get the injury even worse, since you would be stressing the joints further on because there will be no indicators that something is going wrong. Besides, it is not worth going through all of the side effects and suppression seen with deca just for the inflammation reduction.
Instead, it is best to use something that was purposefully created for joint/bone healing, such as Ostarine MK-2866. It has been scientifically proven that it can drastically improve the healing process of joint/bone related injuries and accelerate recovery after surgeries. Another good thing about Ostarine is that it causes no side effects, and the suppression from its use is absolutely minimal. Therefore, no ancillaries are needed, and a very mild PCT will do the job. Also, you can stack in some N2JOint RX - it has a ton of ingredients aimed at reinforcing your joints, and improving joint health.
Personally, I have used this stack when I had very serious elbow problems, and nothing else would help me one bit. However, this stack has helped me big time, and really soon my elbows felt like new. Also, you can stack in some Nutrobal MK-677 - it will stimulate GH production, which will greatly contribute to your joint recovery. It does not have side effects either, and unlike HGH it is very easy to find the real thing.
