At your level of experience, you can get great results running 2cc EW. GP Sust 270 is awesome. You can split it up at 1cc 2x wk or you can take .5mg EOD. I would also use an ai with this. Adex is what I usually suggest. And just because you have recovered without PCT doesn't mean that PCT wouldn't help you recover faster, so I would think about it. The older guys get and the longer they have cycled, the harder it can be to recover. If you are good, so be it. Persoanlly, I suggest it either way to ensure that you keep as much of your gains as possible
