Temper expectations with nandralone and joint relief. Symptom relief, if any, will be temporary only. Remember what nadralone does to potentially relieve joint point and, therefore it's limitations.The thought of throw some deca at my injury is short sighted. I can't say this is your perception, or it doesn't have some merit in certain circumstances. What I'm saying is know why you're doing it and assess to determine if it may help the situation you are in. This idea should be apply to all decisions when considering drugs to address issues. Whether they be symptom or actual cause.
Be aware that nandralone's benefits are not universal and can be exaggerated in many cases. And no doubt, subject to placebo effect.
If you're not already old, dry and inflammed, deca isn't truly helping anything joint wise. It doesn't address soft tissue inflammation pain, again unless it can relieve some friction and resultant inflammation. Already old, dry and inflamed? Different circumstances..... perhaps.
At 37, you may feel some benefits from the addition of nandralone, again - short term directly limited to use. However as
@Goldenrod advised....if the known cause was the weight going on.....get that weight off, at least some. Weight gain like that isn't all going to be lbm.
You may patch job it short term....but the problem isn't going to go away by only addressing symptom, and not cause.
