what I've read about steroids tends to suggest steroids cycles of 6-12 weeks with 'clean' periods. The main issue being suppression of natural T.
I havent read about very short periods of steroid use, probably with good reason - it may make no sense.
however I’d be interested in any experiences of very short periods of steroid use, e.g. a few days, in terms of any gains, side effects (or lack of), whether a few days suppressed natural T and so on.
I guess the usefulness will depend on how the muscle compensates after repairing, if it takes severals days then minimally several days would be needed for an effect from steroids and dosing up for a few days ‘now and then’ may make no appreciable difference compared to simply not bothering with the steroids.
