Yeah, what's the hang up King? Are you still waiting to have that meeting with your hematologist before you see the endo again? If so, I think that's worth the wait. Just to be 100% sure that T isn't going to negatively impact your health.
And that's why we can't in good faith recommend self-medicating. Sure, you can find common dosages out there online. But everybody's body chemistry is different. You don't know how your body will respond to that particular dose, and without a doctor to order and interpret lab results, you'd have no idea what it's doing to your insides. I've spoken to a few guys recently about dosages post-hysterectomy and you'd be surprised at the broad range - some guys stayed the same, many went down, and a few even went up. It's all down to body chemistry and what your body does with the T you get. Like Peep mentioned, taking too much will convert it to E and you'd be extremely fatigued. Not to mention you wouldn't be getting as much masculinization as you otherwise would.
Definitely, definitely worth the wait to do it right and stay health-focused. What's the point of rushing, self-medicating, and wasting money because you were at the wrong dose? Or worse, getting sick because you've damaged your liver or kidneys?
If the endo has spoken to your hematologist and is still dragging his feet, it's time to look for other options. But if it's just wait time between appointments, you'll run into that everywhere, especially when you're first starting.
