there’s not really much of any chance of permanent physical changes that just sneak up on you in weeks, or even a couple months.

At 2 months, I had the start of what seems like technically permanent effects (very clear change in texture under the skin on one side), but like you’d have to be feeling for it and my Dr started me with relatively high starter dose for pills (4mg/day + 100mg/day spiro I think?). If you didn’t want further growth, you could just stop there though. If you don’t want even that change, you should probably assume you’d be far faster than average.
