Endocrine side effects have included inhibition of endogenous testosterone release by means of feedback inhibition of pituitary luteinizing hormone (LH). Large doses of exogenous anabolic steroids may suppress spermatogenesis through inhibition of pituitary follicle stimulating hormone (FSH). The androgenic activity of anabolic steroids may decrease levels of thyroxin-binding globulin and result in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged and there is no clinical evidence of thyroid dysfunction. [ Ref ]
I used to be a carb nazi…I preached that crap for two or three years. And it works!! Really, really well! But intermittent fasting works really, really well too and it disproved the whole theory of insulin response with carbs…I eat whatever the fuck I want nowadays and still maintain under 10% body fat. Leanest dude in my gym by far. Just had 2 pizza burritos full of bacon, pepperoni, grilled chicken, mozzarella and spaghetti sauce on fresh cooked tortillas. I’m a god damned genius for inventing that burrito flavor BTW.
