I've been using 4-chloro-17a-methyl-androst-1,4-diene-3-17b-diol (Halodrol)off and on for the last 2-3 years and have had on-going issues with spasms and inflammation in my left shoulder, trapezius and infraspinatus. These muscles are already prone to soreness due to 20 yrs+ of powerlifting, football, wrestling etc.
I know that stanozolol and other related compounds can cause "dryness" of the joint, but can other steroids aggrivate joint pain through cortisol receptor antagonism or through some other pathway? I know my low-back spasms are aggrevated by this compound just like they are by dianabol.
I know this compound is somewhat related to dianabol, so it seems likely that other muscles can be prone to spasm while on these compounds aside from the low back.
