LDL/HDL Ratio

LDL to HDL Cholesterol Ratio

Category: Lipids
Unit: ratio

Calculated ratio of LDL to HDL cholesterol. A higher ratio indicates greater atherogenic risk. Useful as a quick cardiovascular risk assessment.

PED Notes

AAS dramatically worsen this ratio through a dual mechanism: elevating LDL while simultaneously suppressing HDL. Oral 17-alpha-alkylated steroids cause the most severe distortion — ratios of 5-10+ are common on-cycle (vs ideal <2.5). Trenbolone is particularly harsh. Even injectable testosterone at supraphysiological doses worsens this ratio. Post-cycle recovery of this ratio depends primarily on HDL recovery, which can take 3-6 months.

When high

Understanding LDL/HDL Ratio:

  • <2.0: Optimal cardiovascular risk
  • 2.0-2.5: Near optimal
  • 2.5-3.5: Borderline high risk
  • 3.5: High risk

  • 5.0: Very high risk — common on AAS cycles

Supplements:

  • Citrus Bergamot -- 500mg 2x/day (improves both LDL and HDL)
  • Omega-3 (EPA/DHA) -- 2-4g/day
  • Niacin -- 500-1000mg extended-release (raises HDL, lowers LDL)

Lifestyle:

  • Regular cardio 3-5x/week (most effective intervention — improves HDL)
  • Increase dietary fibre
  • If ratio >5.0 on-cycle, strongly consider shortening cycle or dropping oral AAS
  • Monitor recovery post-cycle — ratio should normalise within 3-6 months

Pharmacological options (when supplements insufficient):

  • The ratio responds to the same pharmacological stack as its component markers; see LDL, ApoB, and HDL markers for detailed protocols
  • Rosuvastatin 5-20mg/day, ezetimibe 10mg/day, bempedoic acid 180mg/day, and PCSK9 inhibitors (alirocumab/evolocumab) lower the numerator
  • Discontinuing oral AAS is the most powerful lever on the HDL denominator
  • All prescription items require physician oversight and baseline liver/CK panel
