Sometimes you can drive a car drunk and not crash, does that make it a good idea??? And how do you know it was all good, because you think you felt fine or because you got bloodwork done and everything went back to normal. You could have felt fine and had the testosterone levels of a 90year old.
There's no rules, you can do anything you want. There's a good possibility you could run many cycles without pct and recover if that's a chance your willing to take.
I have a friend who has been on and off gear for Years and years with no pct or general health supplements and other then the fact he loses all his gains he seems fine, but I'd bet anything if he went to a Dr for bloodwork there wouldn't be some long-term damage being done.
Anyway, clomid at 50/50/25/25 or even just 25mg for 4 weeks is probably fine. If you use 50 and get side effects drop to 25. Also 6mg boron 2x a day will boost free testosterone and that is always good, you can use that on or off cycle.
But by all means, if you feel you will be fine without a real pct that's your choice. We're all adults, and the best part of being a adult is that you can do whatever you want. I would suggest the clomid, I would also suggest that if your into running cycles you get on a couple general heart health supplements year round, not just on cycle. Liver support is also good but not nearly as important, your liver does a pretty good job recovering on its own. But with that said I still use 1000-2000mg nac year round, it's got way more health benifits besides the liver.
Good luck
