Stopping short happens. Nothing to sweat. I'd probably run your PCT for four weeks. At four weeks of pinning 500mg, you're most likely shut down. As far as PCT chems being toxic, from my research your clomiphene citrate is probably more "toxic" as opposed to the tamoxifen citrate. So its possible that you could lower your clomid dosage slightly (if you're concerned about the possible effects on vision) and keep the nolva at more "normal" levels. Perhaps something along the lines of:
Clomid: 50/25/25/25
Nolva: 40/40/20/20
You're only a 1/3rd of the way into your cycle so you should recover much more easily and quickly. Still, do NOT expect to be back at 100% immediately following your PCT. It takes time to recover, even after the proper protocols. Good call on your part by stopping early due to other health issues. If I may ask, what kind of heart issues does a 22yr old have.
