How Much Testosterone Should I Take?

How Much Testosterone Is the Right Amount? A Doctor Breaks It Down

This might be the single most googled question in the TRT world, and the answer frustrates people because it is not a number. It is a process. The Anabolic Doc understands this, and his video on testosterone dosing does something that most content on this topic fails to do: it explains why there is no universal dose and gives you the tools to figure out what is right for you specifically.

The desire for a simple answer is completely understandable. When you are about to stick a needle in yourself, you want to know that the number on the syringe is correct. But testosterone dosing is not like taking ibuprofen where everyone gets the same 400mg tablet. Your ideal dose depends on your body weight, body composition, SHBG levels, metabolic rate, injection frequency, delivery method, and individual sensitivity to androgens. The only way to find it is through careful titration guided by bloodwork and symptom assessment.

The Starting Dose Range and Why It Exists

Most TRT protocols start with testosterone cypionate or enanthate at 100 to 150mg per week. This range exists because it places most men in the mid-to-upper physiological range without overshooting into supraphysiological territory. Starting within this window gives your provider a clean starting point from which to make informed adjustments.

The lower end (100mg/week) is appropriate for men with lower body weight, older men, men with higher SHBG (who convert and metabolize testosterone differently), and men who are particularly concerned about side effects. The upper end (150mg/week) may be more appropriate for larger men, younger men with faster metabolism, and men with lower SHBG levels.

What should raise a red flag is any provider who starts you at 200mg per week or higher without a compelling clinical reason. At 200mg weekly, many men will exceed the physiological range, which is no longer replacement therapy. It is mild enhancement. While some men function well at these levels, starting there makes it impossible to know whether a lower dose would have achieved the same symptom relief with fewer side effects.

The Role of SHBG in Determining Your Dose

Sex hormone binding globulin (SHBG) is a protein produced by the liver that binds to testosterone and renders it biologically inactive. Only the testosterone that is not bound to SHBG (free testosterone and albumin-bound testosterone, collectively called bioavailable testosterone) can enter cells and exert effects. Your SHBG level significantly influences how much of your total testosterone is actually working for you.

Men with high SHBG may have a total testosterone that looks adequate on paper but a free testosterone that is actually quite low. These men often need slightly higher doses to achieve adequate free testosterone levels. Conversely, men with low SHBG may have generous free testosterone levels even with a modest total testosterone reading, and they may be more susceptible to side effects because more of their testosterone is biologically active.

SHBG is influenced by age (it increases with age), body composition (obesity lowers it), insulin resistance (lowers it), thyroid function (hyperthyroidism raises it), liver health, and certain medications. Understanding your SHBG helps explain why two men on the same dose can have different experiences and different lab results.

Injection Frequency: The Other Half of the Dosing Equation

Your dose is only half the equation. How often you inject that dose has a profound impact on how stable your blood levels are and how you feel throughout the week. A man injecting 150mg once per week experiences a significant peak in the first 24 to 48 hours followed by a gradual decline that can leave him feeling flat or symptomatic by day 6 or 7. The same man injecting 75mg every 3.5 days gets the same weekly total but with much smoother, more consistent blood levels.

The pharmacokinetics of testosterone cypionate support frequent dosing. The half-life is approximately 8 days, which means that once-weekly dosing produces meaningful trough-to-peak variation. Twice-weekly dosing cuts that variation roughly in half. Every-other-day dosing produces blood levels that are nearly flat. Some men take this even further with daily injections of 15 to 20mg, which produces the most stable levels possible with injectable testosterone.

More frequent injections also tend to reduce side effects. Estradiol spikes (which follow testosterone peaks) are dampened. Hematocrit elevation is often less pronounced. DHT production is more stable. Mood and energy stay more consistent. The tradeoff is the inconvenience of more frequent injections, but for many men, the improvement in how they feel makes it worthwhile.

Reading Your Bloodwork Like a Pro

When you get your follow-up labs on TRT, there are several numbers that matter for dosing decisions. Total testosterone at trough should ideally fall between 500 and 900 ng/dL, though some providers are comfortable with slightly higher or lower depending on the individual. Free testosterone is arguably more important than total and should be in the upper half of the reference range.

Estradiol (measured by the sensitive LC/MS/MS assay, not the standard immunoassay which is inaccurate in men) ideally sits between 20 and 40 pg/mL, though symptom-free ranges vary between individuals. Hematocrit should stay below 52 percent. PSA should be stable and within the age-appropriate range. A significant increase in PSA warrants urological evaluation even if the absolute number is still "normal."

The timing of blood draws matters enormously. Always draw trough levels for consistency. If you inject twice weekly on Monday and Thursday, draw blood Thursday morning before your injection. This gives you your lowest point, which is the most useful number for dosing decisions. A blood draw taken 24 hours after injection will show a peak that is not representative of your average level and may lead to inappropriate dose reductions.

When Your Dose Needs to Change

Your initial optimized dose may not be your forever dose. SHBG changes with age and health status. Body composition changes affect testosterone metabolism. New medications can alter how your body processes hormones. It is normal to need periodic adjustments, and this is why ongoing monitoring matters even after you feel like your protocol is dialed in.

Life changes can also affect your needs. Significant weight loss may mean you need less testosterone because you are aromatizing less. Increased physical activity may change how you metabolize and use testosterone. Stress, illness, and sleep disruptions can all temporarily alter your hormonal response. A good provider checks labs at least annually on a stable protocol and adjusts when the data warrants it.

Who Should Watch This

This video is for men at any stage of TRT who want a clearer understanding of dosing principles. Whether you are about to start and wondering what dose to expect, currently on TRT and feeling like your dose might not be right, or trying to understand why your protocol looks different from what you read about online, the framework here will help you make sense of your situation and have more productive conversations with your provider.

The Anabolic Doc does an excellent job in this video of cutting through the noise around testosterone dosing and providing a framework that is both scientifically grounded and practically useful. The core principle is simple: start low, use bloodwork and symptoms to guide adjustments, change one variable at a time, and optimize for consistent wellbeing rather than peak numbers. If you follow this framework with patience and a provider who shares this philosophy, you will find the dose that works best for your unique physiology. And that is worth more than any number someone else posted on the internet about their protocol.

The Psychological Dimension of Dosing Decisions

There is a psychological component to TRT dosing that rarely gets discussed. The internet forums and social media communities around TRT create an environment where higher numbers are celebrated and conservative dosing can feel inadequate. When you see men posting about their 1000 ng/dL total testosterone levels, it is natural to wonder if your 650 is somehow not enough. This comparison trap leads many men to push for higher doses than they actually need, chasing numbers rather than how they actually feel.

The Anabolic Doc wisely pushes back against this mentality. The goal of TRT is symptom resolution and health optimization, not achieving the highest possible lab value. A man who feels great, has energy, sleeps well, performs well in the gym, and maintains healthy labs at a total testosterone of 600 ng/dL is better off than a man who feels good but has elevated hematocrit, elevated estradiol, and borderline blood pressure at 1000 ng/dL. More is not always better, and the sweet spot is almost always lower than what the internet would have you believe.

Learning to trust your body's signals over external validation is one of the most important skills in TRT management. If you feel good, your labs are healthy, and your symptoms are resolved, your dose is right regardless of what anyone else is doing. This patient-centered approach to dosing, guided by individual response rather than arbitrary targets, is the foundation of responsible TRT management and the central message of this very useful video.
