IMO it should be taken just as one would a water-based suspension. I'm not sure what the question is....is it about release time of oil-based suspension or injecting a muscle then working it?
Were I to use AAS, I wouldnt work the same muscle I injected on the day of injection to avoid any bruising or trauma that the injection may have caused. For instance I wouldn't pin a shoulder then work shoulders, just to avoid problems. But Im sure some people do.
