Keenan,
You should be fine, if you take into account two considerations:
First, Cortisone shots are specifically designed to reduce swelling in the tissues at the site of injection. However, free cortisol levels will be raised throughout the body. Although most people understand you have to be little easier on the joint where the shot was taken, you are actually at a greater risk "full body" to injury. Be very careful that you are not over stressing any tendon for about 3 weeks following your shot.
Second, cortinsone will decrease the effectiveness of your cycle. It is probably good you are on cycle, so that the overall catabolic state will be kept at a minimum. Just be careful that you don't feel like the slower gains are a result of slower training and overcompensate (see above).
Finally, I would love to hear more about your experiences if you do take the shot. I am currently setting up a study on the effects of cortisol in people who take
AAS, with and without Cytadren and other Anti-E's. Thanks!!
Hope this helps,
Kemo
