This thread is a joke. FACTS: - prolactin can raise even if estrogen is in range - If you are running high test your estrogen should NOT be in natty range, it should be much higher if you want to function and feel good and have good pumps. testosterone to estrogen ratio is important. You don't want to be in natty reference range. - Prolactin does cause gyno if your estrogen is not crushed. Do you want to cycle with crushed estrogen and have a limp dick? You can't be in natty estrogen range and feel great if you are running 400mg+ test. FACT I have done TONS of blood tests and verified it all on myself and there are countless of other people on forums who have indeed gotten gyno from 19nors and normal estrogen levels. Estrogen and prolactin gyno are very different. I've experienced both and gotten rid of both. You absolutely do need caber at hand. But be aware. It's extremely powerful and you need very little. ALWAYS get bloods before taking shit though.
