A-2 Receptors?

I have been doing a lot of research on this topic. I am getting ready for another season of bodybuilding competitions and I have gotten lean, but not striated in the glutes before. I compete as natural bodybuilder. I know that the A2 receptor is the one that is dominant in lower body fat and it uses noradrenaline as it’s “key”.

However, blood flow is low to fat cells, due to only capillaries running to them. I have read that yohimbe can help in breaking down these fat cells, but does anyone have any other advice or ideas? Thanks-Kyle
