What are your actually levels?
I find it very unlikely that you are going to have "very high" levels from being on Test and Tren for 12 weeks. I think you probably have a history of cycling on and off and not looking at the possible consequences it may have on your health. Donating blood is a very common practice among most people that use PEDs. The fact that you are unaware of this is alarming. Being jacked is great, but dying from a heart attack at a young age is not. You need to donate blood.
You should also get more bloodwork done and check your lipids, if you have not. Constant strain on those will also be very detrimental to your health.
