🫘KIDNEY FUNCTION

Renal Health & Filtration Markers

WHAT IT MEASURES

• Creatinine — waste product from muscle metabolism

• BUN (Blood Urea Nitrogen) — protein metabolism byproduct

• eGFR (Estimated Glomerular Filtration Rate) — kidney efficiency

• BUN/Creatinine Ratio — dehydration/kidney stress indicator

• Uric Acid — purine metabolism waste

REFERENCE RANGES

Marker	Normal Range	Note
Creatinine	0.74–1.35 mg/dL (men)	Muscle metabolism
BUN	7–20 mg/dL	Protein breakdown
eGFR	>60 (normal), >90 (optimal)	Filtration rate
BUN/Creatinine Ratio	10–20	Hydration marker
Uric Acid	3.4–7.0 mg/dL	Purine waste

WHY IT MATTERS

High-protein diets, creatine supplementation, and dehydration all stress the kidneys — and heavy anabolic use compounds this burden significantly. Elevated creatinine combined with low eGFR signals declining kidney function. Athletes on cycle should target 3+ liters of water daily. Early-stage kidney stress is silent — by the time symptoms appear, significant damage may have already occurred. Monitor every 8–12 weeks and act before the numbers get out of range.
