Mark Reynolds
Bloodwork & Health Editor
Mark Reynolds writes about bloodwork, health monitoring, cardiovascular markers, liver markers, kidney markers, and practical risk awareness for serious lifters. His work focuses on helping readers understand lab results as context, not as self-diagnosis.

What Mark Covers
Mark covers the health-monitoring side of performance education: CBC, hematocrit, hemoglobin, lipids, liver enzymes, kidney markers, blood pressure, glucose, and related lab work. The goal is to make bloodwork easier to understand without turning lab numbers into internet diagnosis.
His articles are built for adult readers who want clear explanations before going deeper into PED, TRT, hormone, or performance-health content. The writing style is direct, practical, and focused on context: what a marker can suggest, what it cannot prove, and when medical review matters.
CBC, lipids, liver markers, kidney markers, glucose, hormones, and baseline testing.
How to think about trends, repeat testing, timing, symptoms, and health context.
How performance-enhancing drug exposure can change the bloodwork conversation.
Cardiovascular, liver, kidney, and blood-pressure context without fear-based writing.
Bloodwork & Health Articles
These articles are part of the Muscle Science Bloodwork & Health section. They are designed to be read as a sequence: start with baseline testing, then move into specific markers.
Blood Tests Before Steroids: 7 Markers to Check
A starting point for CBC, lipids, liver, kidney, glucose, hormones, and blood pressure before deeper PED research.
CBC GuideHematocrit & Hemoglobin Explained
How red blood cell markers fit into oxygen transport, hydration, TRT context, and performance health monitoring.
Lipid GuideHDL, LDL & Triglycerides Explained
How lipid panel markers connect with cardiovascular risk, PED context, and long-term monitoring.
Liver GuideAST, ALT & GGT Explained
How liver markers fit into training stress, oral PED context, alcohol use, medication pressure, and bloodwork monitoring.
How Mark Approaches Health Content
Mark’s writing avoids two common extremes: panic-based health content and careless forum-style advice. Bloodwork is treated as useful information, not as a replacement for clinical care.
Each guide aims to explain what a marker means, why it may change, what can confuse interpretation, and how it fits into a larger monitoring picture. The practical goal is better questions, clearer context, and fewer reckless assumptions.
Clear Education Before Bigger Decisions
Muscle Science exists to make performance-health topics easier to understand, especially for readers who want more structure, less noise, and better context before making serious decisions.
