OptiPeptide

Testosterone (Total and Free)
Total testosterone reflects your overall levels, while free testosterone measures the active form circulating in your body. Both are key for energy, strength, muscle mass, libido, and overall vitality.

SHBG (Sex Hormone-Binding Globulin)
A protein that binds to sex hormones like testosterone and estrogen, affecting how much is freely available in the body. Imbalances can influence mood, metabolism, and hormone therapy effectiveness.

DHEA-S (Dehydroepiandrosterone Sulfate)
A hormone that serves as a building block for testosterone and estrogen. Supports immune health, energy, and aging.

Cortisol
The primary stress hormone. Imbalances in cortisol can affect sleep, fat storage, energy levels, and recovery.

IGF-1 (Insulin-like Growth Factor 1)
A marker of growth hormone activity. Helps with muscle building, cellular repair, and healthy aging.

Estradiol (E2)
The primary form of estrogen that plays a key role in hormone balance, metabolism, and tissue health in both men and women. Abnormal levels can affect energy, muscle growth, fat distribution, mood, and sexual health. Monitoring estradiol helps optimize peptide and hormone therapy outcomes.

Insulin (Fasting)
Assesses how well your body responds to sugar. High levels may indicate insulin resistance, which can lead to fatigue, weight gain, and metabolic disorders.

Fasting Glucose

Measures blood sugar after fasting. Elevated levels may be an early sign of metabolic issues or prediabetes.

CRP (C-Reactive Protein)
A general marker of inflammation in the body. Elevated CRP can signal chronic inflammation, which is linked to aging and disease risk.

Vitamin D
Important for immune function, hormone balance, bone health, and longevity. Deficiency is common and may affect energy, sleep, and mood.

Vitamin B12
Essential for red blood cell formation, nerve health, and energy production. Low levels can contribute to fatigue and cognitive concerns.

ALT (Alanine Aminotransferase)
An enzyme found in the liver. High levels may indicate liver inflammation or stress.

AST (Aspartate Aminotransferase)
Often paired with ALT to evaluate liver health and injury.

Creatinine + eGFR (Estimated Glomerular Filtration Rate)
These markers assess how well your kidneys are filtering waste. Important for monitoring kidney function and long-term health.

Cholesterol (Total)
Measures all cholesterol types in your blood — a key marker of heart and metabolic health.

HDL (High-Density Lipoprotein)
The “good” cholesterol. Higher levels are protective against heart disease.

LDL (Low-Density Lipoprotein)
Often referred to as “bad” cholesterol. Elevated levels can increase cardiovascular risk.

Triglycerides
Fat in the blood that can rise with poor diet, insulin resistance, or metabolic dysfunction.

VLDL (Very Low-Density Lipoprotein)
Carries triglycerides through the bloodstream. High levels are associated with increased heart disease risk.

CHOL/HDL Risk Ratio
Compares total cholesterol to HDL; a lower ratio is better and suggests lower cardiovascular risk.

LDL/HDL Risk Ratio
Compares “bad” to “good” cholesterol. Helps assess balance and risk more precisely than individual numbers alone.
