Thank you very much for answering my first question, it helped. I have been doing a lot of research the past 2 weeks. Considering my chronic kidney failure and my kidney being stable at 40% function rate, I am strongly considering adding mast to my Test c and Adex stack. I thought about anavar but am too worried about orals filtering through my kidney and being too harsh. Many forums say Mast is a great compliment to test c and considering i am already lean it could work nicely. I also like that Mast, EQ, and primo arent suppose to hold water and shouldnt raise BP, seeing i already have pretty high BP from the test. From what i hear Mast is suppose to be like primo just more affordable, and i did hear EQ can add some water weight. All 3 are suppose to be mild steroids right? So mast enanthate seems to be the best bet to inject with my test c. Do you agree? and will the test with the mast help me put on some lean gains? Your thoughts are greatly appreciated. As you can tell im trying to be very careful, test is all ive ever used, but also hate how hard it is to put on mass considering my medical condition and making sure my bp stays low (cant use the mass gain steroids b/c of this), thanks again in advance
