TRT Bloodwork: What To Monitor
The key labs to track on TRT - when to test, what changes, and how to read your numbers without panic.
Blood Pressure Before a Cycle
Why baseline blood pressure matters before any cycle decision - and how to track it correctly at home.
Estradiol On TRT Explained
Estrogen on TRT - when high E2 is fine, when it isn't, and why most "crashed E2" panic is overblown.
Bloodwork Comes First
01 / CBCComplete Blood Count
Hematocrit, hemoglobin, red and white blood cells - what to monitor and why.
02 / LipidsCholesterol & Lipids
HDL, LDL, triglycerides - how cardiovascular markers shift on PED and TRT.
03 / LiverAST, ALT & GGT
Liver enzymes, training-related noise, and real liver stress in context.
04 / KidneyKidney Markers
Creatinine, eGFR, BUN - hydration, muscle mass, and what really matters.
05 / BaselineBaseline Blood Tests
Key baseline markers to check before TRT, any compound, or a hard training block.
06 / CardioBlood Pressure
Track BP, cardiovascular strain, and long-term health from day one.
Check a Blood Pressure Reading
One of several interactive tools across the site. Set a reading to see its category - then dive into the full guides.
Blood pressure is the most trackable cardiovascular marker, and androgens can push it up. Where does a reading land?
Illustrative categories (ACC/AHA), not a diagnosis - several resting readings on different days are what count. More tools live inside the bloodwork guides.
