Blood test are just as important as incorporating a pct regime,diet, and training. You can feel fine but without bloods you will never really know whats going on inside your body. You should get your blood tested before cycle,halfway through, and around 6 weeks after pct. the blood test done before cycle will let you know if your body is ready for your cycle. The test half way will let you know how your body is reacting to your cycle. And the test 6 weeks after you have completed your pct will let you know if your body has recovered. The tests you should get to see if your body is ready include A complete blood count which will give you an idea of overall health(Liver,kidneys,blood cell health). Another important test is a chemistry panel which lets you know what your Cholesterol,hdl,ldl,Triglycerides,Cholesterol/hdl ratio. Last but not least your bodies hormone levels which include lh,fsh,free testosterone,and estradiol. remember that getting bloods done is just as important as anything else you need to prepare for cycle.hope you enjoy the read hope it helps answer any questions.
