Your data, before we do anything.

Testosterone, Free and Total

Total testosterone measures what's circulating in the blood. Free testosterone measures what your body can actually use — because a significant portion is bound to proteins and unavailable. We use the gold-standard equilibrium dialysis method, which is more accurate than the calculated estimates most labs report. Both values matter, and neither tells the full story without the other.

Estradiol

Estrogen in men isn't optional — it's essential. It protects bone density, cardiovascular function, cognition, and libido. The goal isn't to minimize it; it's to keep it in the right range relative to testosterone. Too high causes fatigue, mood instability, and water retention. Too low causes joint pain, brain fog, and loss of drive.

DHEA-Sulfate

A precursor hormone produced by the adrenal glands that serves as raw material for sex hormone production. DHEA-S declines steadily after age 25 — it's one of the clearest biological markers of aging. Low levels are associated with reduced resilience under stress, accelerated loss of lean mass, and diminished anabolic signaling even when testosterone looks adequate.

IGF-1

The stable proxy for growth hormone activity. Growth hormone itself fluctuates dramatically throughout the day and can't be captured reliably in a single draw. IGF-1, produced by the liver in response to growth hormone, gives us a clean 24-hour average. It drives muscle protein synthesis, cellular repair, fat metabolism, and recovery capacity.

FSH and LH

These are the upstream signals — sent from the pituitary gland in the brain to the testes. They tell us whether a hormone problem originates at the level of the testes themselves or higher up in the signaling chain. That distinction changes the clinical approach entirely. Two people can have the same low testosterone with completely different explanations.

Sex Hormone Binding Globulin (SHBG)

SHBG is a protein that binds to testosterone and makes it unavailable for use. Think of it as a parking brake on your hormonal system. High SHBG can explain why someone has normal total testosterone but still has every symptom of low testosterone — because most of it is locked up and inaccessible. This is one of the most commonly missed reasons for suboptimal hormonal function.

TSH with Reflex to Free T4

TSH — thyroid-stimulating hormone — is the signal the brain sends to the thyroid. It's the first read on whether the thyroid is functioning normally. If TSH falls outside the reference range, we automatically run Free T4 to get the downstream picture. Thyroid function governs metabolic rate, energy availability, body temperature, mood, and how efficiently every other system in the body runs.

Cortisol, A.M.

Cortisol follows a predictable daily curve, peaking in the early morning and tapering through the day. We draw it at the natural peak to capture the adrenal stress response at its highest point. Chronically elevated cortisol — the hallmark of sustained stress load — breaks down muscle tissue, disrupts sleep architecture, drives insulin resistance, and suppresses testosterone production.

PSA Total with Reflex to Free PSA

Prostate-Specific Antigen is a required baseline before initiating any testosterone-based protocol. If total PSA is elevated — above 2.5 ng/mL — we automatically run Free PSA, which helps distinguish benign prostate enlargement from elevations that warrant further workup. This is standard clinical practice, not optional.

Prolactin

Elevated prolactin is one of the more commonly overlooked causes of low testosterone, reduced libido, and persistent fatigue in otherwise healthy men. Prolactin suppresses LH and FSH signaling, which in turn suppresses testosterone production. Elevations can be caused by medications, chronic stress, or occasionally a small benign pituitary growth — all of which require different responses.

Fasting Insulin

The earliest available signal of insulin resistance — often present a decade before glucose or A1c become abnormal. When fasting insulin is elevated but blood sugar still looks normal, it means your body is working significantly harder than it should to maintain that normal range. That window — before glucose climbs — is the most important time to intervene. Standard blood panels almost never include this.

Hemoglobin A1c

A 90-day running average of blood sugar control, reflecting how much glucose has been attaching to red blood cells over the past three months. It captures patterns that a single fasting glucose measurement can't. Values in the high-normal range — even below the clinical threshold for pre-diabetes — are associated with meaningfully higher cardiovascular and metabolic risk over time.

Leptin

Leptin is the hormone produced by fat cells that signals satiety to the brain — it tells your body you've eaten enough and have sufficient energy stores. When leptin resistance develops, the brain stops hearing that signal. The result is persistent hunger, difficulty losing fat despite genuine effort, and a metabolic system working against itself. Elevated leptin in the context of weight gain is a key clinical flag.

Lipid Panel

Total cholesterol, HDL, LDL, triglycerides, and VLDL. The foundation — but not the ceiling — of cardiovascular risk assessment. No single number here tells the story. Triglycerides and HDL together are often more informative than LDL alone, particularly in the context of insulin resistance and metabolic health.

Apolipoprotein B (ApoB)

Every single atherogenic particle — every lipoprotein capable of contributing to arterial plaque — carries exactly one ApoB molecule. That makes ApoB a direct count of cardiovascular risk particles. LDL cholesterol can look acceptable while ApoB tells a different story. Many cardiologists now consider this the most important lipid marker — and it's still not on most standard panels.

Lipoprotein(a) — Lp(a)

A genetically determined cardiovascular risk factor that is largely independent of diet, exercise, or lifestyle. Most people never have it tested in their lifetime. If it's elevated, the clinical approach to everything else in the panel shifts — because Lp(a) acts as an amplifier for other risk factors. You can't change your Lp(a) level, but knowing it changes how aggressively we manage everything around it.

High-Sensitivity CRP (hs-CRP)

A highly sensitive marker of systemic, low-grade inflammation — the kind that standard CRP measurement misses entirely. Chronic low-grade inflammation is now understood to be a primary driver of cardiovascular disease, accelerated aging, and metabolic dysfunction. Elevated hs-CRP often shows up before any clinical symptoms, which is precisely why we measure it.

Homocysteine

An amino acid that, when elevated, causes direct structural damage to blood vessel walls. It's independently associated with cardiovascular risk, cognitive decline, and accelerated tissue aging. The good news: elevated homocysteine is often correctable with targeted B vitamin support — specifically folate, B6, and B12. We run it alongside those markers to see the full picture.

Folate, Serum

A B vitamin critical for DNA synthesis, repair, and methylation — the cellular process that governs gene expression, detoxification, and neurotransmitter production. Deficiency is more common than most people assume, even in those eating a balanced diet. Folate levels are directly tied to homocysteine: when folate drops, homocysteine rises.

Vitamin B12

Required for neurological function, red blood cell production, and methylation. B12 deficiency can cause fatigue, cognitive slowing, and peripheral nerve damage — and it often develops slowly, producing subtle symptoms for years before becoming clinically apparent. Certain medications (notably metformin and PPIs) deplete B12 directly.

Magnesium

Magnesium is a cofactor in over 300 enzymatic reactions. It's involved in energy production, muscle contraction, sleep regulation, insulin signaling, and cardiovascular function. Most people — including athletes — are functionally low, because intensive exercise and chronic stress both deplete it rapidly. Standard serum magnesium can look normal even when cellular stores are depleted, which is why we interpret it in clinical context.

Vitamin D, 25-Hydroxy

Despite the name, vitamin D functions more like a hormone than a traditional vitamin. Its receptors are present in virtually every tissue in the body — including muscle, bone, immune cells, and the brain. Deficiency is widespread, even in sunny climates, and is associated with reduced muscular performance, impaired immune function, mood dysregulation, and hormonal imbalance across multiple axes.

Zinc

Zinc is essential for testosterone biosynthesis, immune defense, wound healing, and protein synthesis. It's one of the most common — and most correctable — micronutrient deficiencies in men who train hard. Intense exercise, psychological stress, and certain medications all deplete zinc. Low zinc can meaningfully suppress testosterone even when the hormonal signaling cascade is otherwise intact.

Copper

Copper works closely with zinc, and the ratio between the two matters as much as either number in isolation. Copper is required for iron metabolism, connective tissue integrity, neurological function, and antioxidant defense. High-dose zinc supplementation — without monitoring — can deplete copper significantly. We look at both together.

Iron, TIBC, and Ferritin Panel

Three values that together give the complete picture of iron status. Iron (circulating), TIBC (the body's transport capacity), and ferritin (stored iron) each tell a different part of the story. Low ferritin is one of the most common and underdiagnosed causes of persistent fatigue in otherwise healthy, high-functioning adults. Worth noting: ferritin also rises with inflammation, so an elevated ferritin can mean iron excess — or it can be a stress response. Context is everything here.

Comprehensive Metabolic Panel (CMP)

A 14-marker panel that covers kidney function (BUN, creatinine, eGFR), liver function (alkaline phosphatase, AST, ALT, bilirubin), blood glucose, protein status (total protein, albumin), and electrolytes (sodium, potassium, chloride, CO₂, calcium). This is the baseline safety read on your body's core organ systems — essential before and throughout any clinical protocol.

Phosphorus

Not included in the standard CMP, which is why we order it separately. Phosphorus plays a central role in bone metabolism, energy production (it's a component of ATP — the body's energy currency), and cell membrane integrity. It's also closely linked to calcium balance and kidney function. A value that looks fine in isolation can shift significantly in the context of other markers.

Uric Acid

Most people associate uric acid with gout — and that's a legitimate concern — but it's also increasingly recognized as an independent marker of metabolic dysfunction and insulin resistance. Chronically elevated uric acid is associated with cardiovascular and kidney risk that is distinct from its role in joint inflammation. It also reflects fructose metabolism and purine turnover, both relevant in the context of performance nutrition.

Complete Blood Count with Differential (CBC)

The full blood cell picture — red cells (oxygen-carrying capacity, anemia), platelets (clotting function), and a detailed breakdown of every white blood cell type: neutrophils, lymphocytes, monocytes, eosinophils, basophils. This is a standard baseline before any protocol with anabolic effects, and a useful ongoing monitor for immune status and red blood cell parameters over time.

GGT — Gamma-Glutamyl Transferase

A liver enzyme that's particularly sensitive to metabolic burden, alcohol load, and oxidative stress — often rising before other liver markers show any change. Elevated GGT is independently associated with cardiovascular risk and metabolic syndrome, beyond its use as a liver marker. It tends to be a sensitive early indicator that something in the metabolic load equation has shifted.

Creatine Kinase (CK)

An enzyme released into the bloodstream when muscle tissue breaks down. We establish a baseline before initiating any performance protocol so we have a reference point. Elevated CK can indicate overtraining, rhabdomyolysis risk, or underlying muscle conditions. It also helps us interpret follow-up values in context — a CK that rises on protocol means something different than one that was already elevated at baseline.

Lipase

The primary enzyme produced by the pancreas to digest dietary fat. Elevated lipase can indicate pancreatic inflammation or stress. We include it as part of the organ function baseline, particularly relevant in the context of metabolic health, high-fat dietary approaches, and any protocol that impacts lipid metabolism.
