Triglycerides/HDL Ratio
Triglycerides to HDL Cholesterol Ratio
The ratio of fasting triglycerides to HDL cholesterol. Serves as an accessible proxy for insulin resistance and small dense LDL particle predominance. A ratio above 2.0 is associated with insulin resistance and elevated cardiovascular risk; above 3.5 is strongly predictive of metabolic syndrome. Lower is better.
PED Notes
AAS users face a compounded problem: androgens, especially oral compounds, suppress HDL (raising the denominator problem) while high-calorie bulking diets and GH-related insulin resistance elevate triglycerides. MK-677, by chronically elevating GH and IGF-1, produces insulin resistance that worsens fasting triglycerides substantially, often pushing the ratio above 3.0 even without traditional AAS. This ratio is more informative in PED users than in the general population because it integrates both lipid and metabolic dysfunction simultaneously.
When Triglycerides/HDL Ratio is HIGH
A high triglycerides/HDL ratio indicates an atherogenic, insulin-resistant metabolic state. In the general population, this pattern is driven by visceral adiposity, physical inactivity, high refined carbohydrate intake, and genetic predisposition. The ratio correlates strongly with elevated small dense LDL particle count (pattern B LDL), which is more atherogenic than large buoyant LDL because small dense particles penetrate the arterial endothelium more readily and are more susceptible to oxidation.
Research from Gaziano et al. (2000) found that a triglycerides/HDL ratio above 4.0 predicted myocardial infarction risk as strongly as LDL alone, and the PREDIMED trial demonstrated that Mediterranean diet interventions significantly reduced this ratio alongside cardiovascular events. In insulin-resistant states, elevated hepatic VLDL production raises triglycerides while simultaneously suppressing HDL via cholesteryl ester transfer protein (CETP) activity.
Management steps:
- Omega-3 (EPA/DHA) -- 3-4g/day: most effective supplement for lowering triglycerides (reduces hepatic VLDL production by 25-30%)
- Berberine -- 500mg 2-3x/day before meals: activates AMPK, improving insulin sensitivity and reducing hepatic triglyceride synthesis
- Niacin (Extended-Release) -- 1000-2000mg/day: simultaneously lowers triglycerides and raises HDL, directly improving the ratio from both ends
- Reduce refined carbohydrates, fructose, and alcohol: these are the primary dietary drivers of elevated VLDL triglycerides
- Regular aerobic exercise 30-45 min, 4-5x/week: the most effective lifestyle intervention for raising HDL and lowering triglycerides concurrently
- 12-hour fast before blood draw: fasting is mandatory for accurate triglyceride measurement
PED-Specific Considerations: Oral AAS suppress HDL through upregulation of hepatic triglyceride lipase, which accelerates HDL catabolism, directly worsening the denominator of this ratio. Compounds ranked by HDL suppression (worst to least): Stanozolol, Oxandrolone, Oxymetholone, Oral Trenbolone, Boldenone, injectable Testosterone, Nandrolone. GH and MK-677 worsen the ratio from the triglyceride side by inducing insulin resistance and increasing hepatic VLDL secretion, particularly at higher doses. On a combined AAS plus MK-677 cycle, it is common to see ratios of 4.0-6.0, representing a substantially atherogenic metabolic state that warrants aggressive dietary and supplemental intervention.
When Triglycerides/HDL Ratio is LOW
A low ratio (below 1.5) is desirable and reflects good insulin sensitivity, healthy lipid metabolism, and a low-risk particle size distribution (predominantly large buoyant LDL). Elite endurance athletes often achieve ratios below 1.0 through sustained aerobic training and lean body composition.
PED-Specific Considerations: TRT at physiological replacement doses (maintaining testosterone in the mid-normal range) does not significantly worsen this ratio, particularly with concurrent aerobic training. Nandrolone decanoate shows the least negative impact on HDL among injectable AAS. A low ratio on cycle is a positive finding and suggests dietary and exercise habits are effectively offsetting the lipid impact of PED use.
