Getting your TRT dose right is the difference between feeling transformative results and spinning your wheels. Too low, and your symptoms persist. Too high, and you're dealing with elevated hematocrit, estrogen issues, and unnecessary side effects. The goal is the minimum effective dose that resolves your symptoms and puts your labs in range.
Starting Doses by Delivery Method
Testosterone Cypionate and Enanthate
These two esters are functionally interchangeable, so dosing guidance applies to both.
Standard starting dose: 100-120mg per week
Most TRT clinics start patients at 100mg per week, divided into two injections of 50mg each (typically Monday/Thursday or Tuesday/Friday). This is conservative by design -- it's easier to increase a dose than to deal with the side effects of starting too high.
Typical therapeutic range: 100-200mg per week
The majority of men achieve optimal levels somewhere in the 120-180mg per week range. Going above 200mg/week for TRT purposes is unusual and often unnecessary. If you need more than 200mg/week to maintain normal levels, your provider should investigate absorption issues or compliance.
Split dosing matters. A single weekly injection of 200mg creates a spike-and-trough pattern that many men feel. Dividing the same 200mg into two 100mg injections (or even three 66mg injections) produces more stable blood levels, reduces estrogen conversion, and typically feels better.
Testosterone Propionate
Due to its shorter half-life (2-3 days), propionate requires more frequent dosing.
Typical dose: 25-50mg every other day, or 15-25mg daily
Total weekly dose ends up in the same 100-200mg range as cypionate/enanthate, just split into more frequent, smaller injections.
Testosterone Cream (Compounded)
Scrotal application: 50-100mg daily (typically 100-200mg/mL concentration, applying 0.5-1mL)
Non-scrotal (shoulder/arm): 100-200mg daily, as absorption is lower on regular skin
Cream dosing is less precise than injections because absorption varies by individual. You'll need labs 4-6 weeks after starting to gauge how much you're actually absorbing.
Testosterone Gel (AndroGel, Testim)
Standard starting dose: 50mg daily (one pump or packet)
Adjustment range: 25-100mg daily
Gels have the most variable absorption of any delivery method. Some men metabolize gel testosterone so poorly that even maximum doses produce subtherapeutic levels. If you're not responding to gel after 6-8 weeks with proper application technique, consider switching to injections rather than continuing to increase the dose.
Testosterone Pellets (Testopel)
Typical dose: 6-12 pellets (450-900mg total), inserted every 3-6 months
Pellet dosing is estimated based on your body weight, SHBG, and target levels. Most providers use a formula to calculate the number of pellets, but it remains somewhat imprecise. Your first insertion is a best guess -- subsequent insertions are adjusted based on how you responded.
Oral Testosterone (Jatenzo)
Starting dose: 237mg twice daily with food
Range: 158-396mg twice daily
Dose adjustments occur based on total testosterone levels drawn 2-4 hours after a dose with food. The requirement for fat-containing meals complicates consistent absorption.
How to Know if Your Dose is Right
The right dose satisfies two criteria simultaneously: your symptoms improve, and your labs are in range.

Trough levels matter. Always draw labs at your trough -- the morning of your next injection, before injecting. Trough levels tell you the lowest your testosterone drops between doses. If your trough is 700 ng/dL, your peak is likely 1000+ ng/dL, and your average across the week sits comfortably in range.
Peak levels are less useful because they vary dramatically based on when you injected, the ester used, and injection site.
Symptom Assessment
Labs only tell part of the story. Two men with identical testosterone levels can feel completely different. When evaluating your dose, track these symptoms weekly:
- Energy and motivation -- improving, same, or worse?
- Libido -- present, absent, or excessive?
- Mood -- stable, irritable, anxious, flat?
- Sleep quality -- sleeping better or worse?
- Erection quality -- morning erections returning?
- Body composition -- gaining muscle, losing fat, or stalled?
If your labs look good but symptoms persist, the dose may still need adjustment. If symptoms are great but labs are out of range, trust the labs -- something needs to change.
Dose Adjustment Protocol
When to Adjust
Don't adjust your dose based on how you feel in week 2. Testosterone cypionate takes approximately 5 half-lives (about 40 days) to reach steady state. Wait a minimum of 6 weeks before drawing labs or making dose changes.
How to Adjust
Step 1: Draw trough labs at 6-8 weeks.
Step 2: Evaluate total T, free T, estradiol, and CBC together -- not in isolation.
Step 3: Adjust by 10-20mg per week increments. Smaller changes are better. A jump from 100mg to 200mg is reckless -- go to 120mg, then recheck in 6 weeks.
Step 4: Re-draw labs 6 weeks after any change.
Common Scenarios
Trough testosterone below 500 ng/dL, symptoms persist:
Increase dose by 20mg/week. You're undertreated.
Trough testosterone 700-900 ng/dL, symptoms resolved:
You're dialed in. Maintain this dose and recheck labs every 6 months.
Trough testosterone above 1000 ng/dL:
Decrease dose by 20mg/week regardless of how you feel. Supraphysiological levels increase cardiovascular and polycythemia risk over time.
Testosterone in range but estradiol above 40-50 pg/mL:
Consider increasing injection frequency first (e.g., from twice weekly to every other day). More frequent dosing reduces the testosterone peaks that drive aromatization. If that fails, see our estradiol management guide.
Hematocrit above 52%:
Donate blood, reduce dose by 10-20mg, or increase injection frequency. If hematocrit remains elevated, discuss therapeutic phlebotomy with your provider. A good TRT clinic will catch this early and adjust proactively -- compare clinics that monitor bloodwork closely.
Micro-Dosing and Daily Injections
A growing number of TRT patients inject daily using insulin syringes (27-31 gauge). Instead of 150mg split into two weekly injections of 75mg, they inject approximately 21mg every day.
Benefits of Micro-Dosing
- More stable levels: Smaller peaks and troughs, which can reduce estrogen conversion, mood swings, and acne
- Lower hematocrit: Studies suggest more frequent dosing is associated with lower hematocrit increases
- Less need for an AI: The reduced peak testosterone levels mean less aromatase activity
- Smaller injection volume: Daily doses of 0.1-0.15mL are virtually painless with a 29-gauge insulin needle
Downsides
- Daily commitment: You must inject every day, and missing doses is more impactful with smaller individual doses
- More injection sites needed: You need a robust rotation schedule to avoid scar tissue buildup
- Potentially lower peaks: Some men feel better with moderate peaks and don't like the "flatline" feeling of perfectly stable levels
Micro-dosing isn't for everyone, but it's worth trying if you're struggling with estrogen management or side effects on twice-weekly protocols.
Overtreating vs Undertreating
Signs You're Overtreated
- Hematocrit climbing above 52%
- Elevated estradiol with symptoms (bloating, nipple sensitivity, mood swings)
- Acne, oily skin, hair thinning
- Elevated blood pressure
- Restless sleep, night sweats
- Irritability or aggression
Overtreating is more common at clinics that chase supraphysiological levels. "More testosterone" does not mean "more benefits" beyond a certain point. The risk-to-benefit ratio worsens above approximately 1000-1100 ng/dL for most men.
Signs You're Undertreated
- Persistent fatigue despite 6+ weeks on TRT
- No improvement in libido or sexual function
- Trough levels below 500 ng/dL
- No change in body composition with consistent training
- Depression or brain fog unchanged
Undertreating is more common with conservative endocrinologists who aim for mid-range levels (400-600 ng/dL) without considering that optimal levels for most men on TRT are in the 700-900 ng/dL range.
Special Considerations
SHBG and Free Testosterone
Sex hormone-binding globulin (SHBG) binds testosterone and makes it biologically inactive. If your SHBG is high (above 50 nmol/L), you may need a higher total testosterone level to have adequate free testosterone. Conversely, low SHBG (below 20 nmol/L) means more free testosterone at any given total level.
This is why checking free testosterone alongside total testosterone matters. A man with total T of 600 ng/dL and low SHBG may have more bioavailable testosterone than a man with total T of 900 ng/dL and high SHBG.
Body Weight and Dose Requirements
Heavier men generally need higher doses. More adipose tissue means more aromatase enzyme, which converts testosterone to estradiol. A 250-pound man may need 180mg/week to achieve the same levels a 170-pound man gets from 120mg/week.
Age
Older men (65+) typically need lower doses. The risk-benefit calculation shifts, and conservative dosing with careful monitoring is appropriate. The Endocrine Society recommends against targeting the upper end of the reference range in elderly patients.
The Bottom Line
Start at 100-120mg per week of cypionate or enanthate, split into two injections. Wait 6-8 weeks. Draw trough labs. Adjust by 10-20mg increments. Repeat until symptoms resolve and labs are in range. Resist the urge to make big dose changes or chase numbers above 1000 ng/dL.
The best TRT dose is the lowest dose that makes you feel like yourself again. The right provider makes dialing in your dose significantly easier -- see our TRT clinic reviews.
