I do not think you understand. Your doctor has told your that levels below 300 are just as much risk as levels over 1200, making 300-1200 the medium for optimal health, you could up your dose to around 200mg per week and run off that, but I would not recommend any more. 500mg per week will put you well between 2000 and 2500 ng/dl and raise your BP significantly, especially when taking weight into account.
What you need to do is diet down to 15% at least on 125mg-200mg maximum in a calorie deficit, what you eat is also vastly more important than how you exercise. The changes you could make off that alone on 200mg would be significant providing your training was on point and then reassess whether you should up your dose or not providing your BP is dropping to with mid-range and you are not having any issues with your blood clots, I assume you would be aware that regular scans would be necessary.
Avoid any other compounds like the plague. If you are susceptible to clots the last thing you want is one in your brain, my Dad recently had a stroke and I can tell you he is not having a fun time. Equipoise and Trenbolone specifically I would steer clear from.
It is best to take things slow instead of jumping in and potentially risking your life for the sake of gaining muscle faster. I am not sure if you are aware but even with drugs decent results can take years. It's a slow game, even with steroids, so take it easy at first and look after yourself.
I have seen first hand where people have used nothing over 200-250mg of testosterone and made significant progress. This is a guy I know on another forum for instance who is on TRT of only 125mg per week, granted though, he is fairly light at around 160lb, hence needing less gear in but you can grasp where I am coming from. He can perform weighted dips with 50kg+ and weighted pull-ups with 60kg+, he is a machine, and it's due to diet and training, not drugs.
To also put your mind at ease TRT will help with your anaemia as higher testosterone stimulates erythropoiesis. Leave the Deca IMO, just stick to the test, you do not need it.
