you just need to get a basic CBC and liver kidney function test. make sure liver enzymes aren't super elevated, creatinine levels are in range, HDL/LDL are in range, as well as RBC, hemoglobin, and hematocrit.
if those things are all in range then your good to go for your next cycle

if you got the extra $ you can always add in hormone testing, thyroid , total and free test, e2 , just to see where your at with your TRT protocol

I would add in TUDCA for liver support, maybe some alpha lipoic acid as well

also being your running GH releasing peptides it would be good for you to monitor your blood sugar. glucose meter can be picked up at Walmart for 10 bucks
