Is PS still effective now that its made of soy or cabbage sources instead of bovine? Can a person supplement it by eating beef brain instead? I got some belly fat that just won't go away.
Even if you find a form of this compound from a quality source and it does what they claim it does, manually overriding a portion of your endocrine system is a terrible idea. If you do have cortisol levels that are elevated outside of an optimal range, you ought to address the root causes rather than treating the symptom. There's no pill that's going to healthfully negate lack of sleep, an overabundance of stress, or a diet that doesn't correctly replete glycogen stores.
I would avoid anything made of soy simply because it's made of soy regardless of whether or not it's effective for fat loss. I feel like questions like these are better suited for a body building or weight loss forum where the focus is on physical appearance. Paleo is about health holistically, not just an end goal of looking good by any effective means.
