The article you linked is bull****, actually. SERMs don't cause cancer in humans, despite what rat studies say. It's just a way for companies to move more product. Clomid is the perfect thing to use in PCT, and HCG should be used according to the swale (Dr. Crisler) protocol for every cycle. I don't think anyone has shown cortisol increasing after a cycle, that's just speculation that it overshoots and causes catabolism. If you want to keep gains, SARMs are far better than cortisol control products.
