The problem

Testosterone goes undiagnosed

Most men chalk up fatigue, low libido, and weight gain to aging. They never test. The ones who do often get a single number—total testosterone—which misses the full picture.

The science

Markers we read for testosterone

These biomarkers reveal the root causes — and what actually works to fix them.

Total Testosterone
The headline number, but only part of the story
Free Testosterone
The biologically active form that actually matters
SHBG
Sex hormone binding globulin, determines how much T is available
LH
Luteinizing hormone, tells you if the problem is brain or testes
Estradiol
Testosterone converts to estrogen, critical to monitor
Prolactin
Elevated prolactin suppresses testosterone, often missed
Quick answer

What you need to know about low testosterone

Prevalence: 1 in 4 Indian men over 30 have suboptimal testosterone levels.
Common symptoms: Fatigue, low libido, brain fog, muscle loss, and mood changes often go undiagnosed.
The testing reality: Don't self-medicate. You need complete panel testing: total testosterone + free testosterone + SHBG + LH + FSH + estradiol + prolactin. A single "total T" number misses the diagnosis.
Why it matters: Treatment depends on whether the cause is primary (testicular dysfunction) or secondary (pituitary/brain signaling failure). Different patterns require different approaches.

The testosterone biomarker panel

Your physician interprets each marker in context — they work together to reveal the root cause.

Marker What It Measures Optimal Range Why It Matters
Total Testosterone All testosterone in blood (bound + free) 300–1000 ng/dL The headline number — but only part of the story. Many men feel terrible at 'normal' levels.
Free Testosterone Testosterone not bound to proteins (bioavailable) 8.7–25.0 pg/mL The form that actually affects you. A man with high total but low free T still suffers.
SHBG Sex hormone binding globulin (binds & deactivates T) 24–122 nmol/L High SHBG traps testosterone, leaving little free T available. Lifestyle changes can lower it.
LH (Luteinizing Hormone) Brain signal telling testes to produce T 1.7–8.6 mIU/mL If T is low and LH is high = primary problem (testes not responding). If LH is low = secondary (brain not signaling).
FSH (Follicle-Stimulating Hormone) Brain signal for sperm production 1.5–12.4 mIU/mL Often elevated in primary hypogonadism. Useful for assessing fertility impact.
Estradiol Testosterone converts to estrogen (aromatization) 0–40 pg/mL (men) High estradiol + high T = excess aromatization. Common if overweight or on certain treatments.
Prolactin Hormone suppressing testosterone & dopamine 2–18 ng/mL Elevated prolactin suppresses LH and T. Can indicate prolactinoma or other pituitary issue.
DHT (Dihydrotestosterone) More potent testosterone metabolite 15–71 pg/mL Responsible for androgenic effects (muscle, libido, beard growth). Matters for hair loss diagnosis.
Cortisol Stress hormone suppressing testosterone 10–20 μg/dL (morning) Chronic elevated cortisol suppresses LH and T. Often the hidden culprit.
Diagnosis

Low testosterone: pattern → diagnosis → treatment

Lab patterns tell the story. Your physician matches your results to the right protocol.

Lab Pattern
Low T + High LH
Likely Cause
Primary Hypogonadism
Testes are failing to respond to LH signal
Treatment Approach
TRT (testosterone replacement) or fertility preservation. Lifestyle changes have limited impact.
Lab Pattern
Low T + Low LH
Likely Cause
Secondary Hypogonadism
Brain (pituitary) not signaling testes properly
Treatment Approach
Investigate cause (obesity, sleep apnea, chronic stress). Address root issue first. May need HCG or TRT.
Lab Pattern
Low T + High Prolactin
Likely Cause
Prolactinoma / Hyperprolactinemia
Elevated prolactin suppresses LH and T
Treatment Approach
Urgent: MRI to rule out pituitary tumor. Often responds to dopamine agonists. Requires specialist.
Lab Pattern
Low T + High SHBG
Likely Cause
SHBG Binding Issue
T is produced but trapped by binding proteins
Treatment Approach
Reduce liver inflammation, improve insulin sensitivity, lose fat, boost magnesium. Often responds well to lifestyle.
Lab Pattern
Low T + High Estradiol
Likely Cause
Excess Aromatization
Testosterone converting to estrogen (often from fat tissue)
Treatment Approach
Aggressive weight loss, reduce alcohol, support liver health. May need aromatase inhibitor if on TRT.

Why arq. for testosterone

Most platforms
Sell testosterone boosters (ashwagandha, tribulus) without testing. No bloodwork. No diagnosis of what's actually low or why.
arq. approach
Tests total T, free T, SHBG, LH, estradiol, and prolactin. Your physician identifies whether it's primary, secondary, or lifestyle-driven before any intervention.

Member story
My total T was 'normal' at 380. But free T was in the bottom 5th percentile. SHBG was sky high. Now I understand why I felt like garbage.
Summary

5 things you need to know

1. Low T is prevalent in India. 1 in 4 men over 30 have suboptimal testosterone. It's not rare, and it's not something to be ashamed of addressing.
2. Testing must be comprehensive. Total testosterone alone misses the diagnosis. You need free T, SHBG, LH, FSH, estradiol, prolactin, and context about your symptoms.
3. Root cause determines treatment. Primary hypogonadism (testes failing) differs from secondary (brain not signaling). Diagnosis is essential before intervention.
4. Lifestyle changes work—for secondary cases. Sleep, strength training, stress management, and weight loss can restore T if the cause is lifestyle-driven. They won't work for primary disease.
5. Monitoring is non-negotiable. Whether you use TRT, supplements, or lifestyle changes, retest every 8–12 weeks. Adjust based on new data, not guesswork.

Questions

Frequently asked about testosterone

What is normal testosterone level for Indian men?
Normal total testosterone for adult men is typically 300–1000 ng/dL. However, 'normal' lab ranges don't account for symptoms or life stage. A man at 350 ng/dL might feel fatigued while someone at 500 feels energized. Free testosterone (not bound to SHBG) often matters more than total. Indian men show declining T levels over time, so your baseline and trajectory matter more than hitting an arbitrary number. Your physician compares your results to age-matched peers and your own symptom profile.
What are symptoms of low testosterone?
Common symptoms include persistent fatigue, low libido, erectile difficulties, reduced muscle mass despite training, increased body fat (especially around the belly), brain fog, mood changes (depression or anxiety), and poor recovery from exercise. Many men dismiss these as 'normal aging' and never get tested. The tricky part: overlapping symptoms can also signal thyroid dysfunction, sleep apnea, or depression. That's why blood work is essential—it rules out confounders and pinpoints whether testosterone is actually the root cause.
How to increase testosterone naturally?
Lifestyle forms the foundation: consistent strength training (especially heavy compounds), 7–9 hours of sleep, stress management, and adequate nutrition (zinc, vitamin D, magnesium). Alcohol and excess body fat suppress T. Once you know your markers—whether T is low, or SHBG is blocking free T, or LH is suppressed—your physician tailors recommendations. For some, sleep and lifting solve it. Others need supplementation or, rarely, prescription support. Skip the guesswork: test first, then act.
Is TRT safe in India?
Testosterone replacement therapy (TRT), when prescribed by a licensed physician and properly monitored, can be safe and effective. The risks arise from unmonitored use (buying testosterone online, self-dosing) or ignoring side effects like polycythemia or liver strain. In India, TRT requires ongoing lab work and physician oversight—arq. monitors your response with repeat biomarkers and adjusts doses accordingly. The real question isn't whether TRT is safe, but whether it's the right choice for you. Many men improve with lifestyle changes alone.
What blood tests for low testosterone?
Essential tests include total testosterone, free testosterone (the active form), and SHBG (sex hormone binding globulin, which determines how much T is available). You also need LH (luteinizing hormone, tells you if the problem is brain or testes), estradiol (testosterone converts to estrogen), and prolactin (elevated levels suppress T). Many clinics test only total T and miss the diagnosis. arq. runs all six markers plus 94 others—a complete picture that reveals whether your issue is primary (testes failing), secondary (brain not signaling), or lifestyle-driven.
Does low testosterone cause weight gain?
Yes. Low testosterone increases fat storage (especially visceral fat around organs), decreases muscle synthesis, and slows metabolism. Men with low T often gain 5–10 kg despite unchanged diet or activity. Ironically, excess fat worsens the problem: fat tissue converts testosterone to estrogen, further suppressing T. It's a spiral. The good news: restoring testosterone—whether through lifestyle or prescription—reverses this. Expect improved body composition, muscle recovery, and metabolic rate as T normalizes. It takes weeks to months, not days.
Testosterone replacement therapy India cost?
In India, initial blood work at arq. costs around 3,000–5,000 rupees. Physician consultations and protocol fees vary, but the full assessment typically runs 8,000–15,000 rupees. If TRT is prescribed, ongoing medication (gels, injections, or pellets) ranges from 2,000–8,000 per month depending on type. Government labs offer cheaper testing, but you lose physician guidance and integrated care. arq. bundles testing, diagnosis, and follow-up monitoring into one transparent fee—no hidden costs. Compared to private endocrinologists or international telemedicine, it's competitive.
How does arq. test testosterone?
arq. schedules a home blood draw (you don't go to a lab). A trained phlebotomist draws your blood in 10 minutes. Samples go to NABL-accredited labs for analysis. You get results in 5 days. Unlike standard clinics that test one or two markers, arq. measures total testosterone, free testosterone, SHBG, LH, estradiol, prolactin, and 94 other biomarkers—thyroid, metabolic markers, inflammation, liver and kidney function. Your physician reviews the full dataset, identifies root causes, and builds a protocol specific to your numbers and symptoms. Then you get follow-up testing every 8–12 weeks to verify the protocol is working.
