Beyond 1 cc: Making Sense of Real TRT Dosing
This article takes an evidence-minded, non-promotional look at those questions. We’ll explain what “1 cc of testosterone” really means, how mg and mL relate, and why decisions about weekly testosterone injections must be individualized-never based on a single number from a forum.
What Testosterone Does (and Why Low Levels Matter)
Testosterone is a key hormone for male health. It plays a role in:
-
Muscle growth and maintenance
-
Bone density and structural strength
-
Libido and sexual function
-
Mood, motivation, and cognitive drive
As men age, testosterone levels may decline. Some develop true hypogonadism, with symptoms such as fatigue, low libido, reduced strength, increased fat around the midsection, and mood changes. For men with documented low testosterone and compatible symptoms, testosterone replacement therapy can help restore levels toward a healthy range and may improve daily functioning when used and monitored correctly.
In the United States, prescription testosterone is approved for men with specific forms of hypogonadism confirmed by lab testing. Treating “age-related low testosterone” often falls into off-label territory and should be discussed carefully with a licensed clinician.
Why “How Much TRT Per Week?” Has No Single Answer
Searches like how much TRT per week, how much test should I take a week, or how much test to take a week suggest there might be one ideal dose—140 mg, 150mg testosterone per week, or a fixed volume like 1 cc. In real clinical practice, there is no universal dose.
A responsible clinician individualizes TRT based on:
-
Baseline total and (when appropriate) free testosterone
-
SHBG and other lab markers
-
Symptoms and overall health history
-
Body size, metabolism, and concurrent medications
-
Follow-up labs and how the patient feels over time
Because of this, two men can end up with very different weekly exposures. One might do well on something roughly comparable (from a milligram standpoint) to 125 mg of testosterone a week, another on 140 mg of testosterone a week or 150mg testosterone per week, while a third may need less than that.
These numbers are illustrative, not recommendations. The goal of TRT is not to chase a famous internet dose, but to reach and maintain a safe, healthy range with acceptable symptoms and side-effects under medical supervision.
What Does 1 cc of Testosterone Actually Mean?
A major source of confusion is mixing volume (cc or mL) with dose (mg).
Common injectable concentrations include:
-
100 mg/mL → here 1 cc of testosterone = 100 mg
-
200 mg/mL → here 1 cc of testosterone = 200 mg
So when someone asks how many mg is 1 cc of test, the honest answer is: it depends on the vial. A half cc at 200 mg/mL equals 100 mg, while 1.5 mL of a 100 mg/mL product also equals 150 mg.
That’s why questions like how many cc of testosterone should I take a week or how many cc of testosterone a week are really just conversion questions. Clinically, what matters is how many milligrams of testosterone per week you receive, not the raw volume in the syringe.
Some high-concentration products discussed online (for example, “test 400 for TRT” or brands such as “testex 400”) place even more milligrams into each cc. In those cases, misreading the label can easily turn “1 cc” into a much higher-than-intended dose.
Is 1 cc of Testosterone a Week Enough?
Back to the main question: Is 1 cc of testosterone a week enough?
The evidence-minded answer is: it depends—on concentration, your lab values, your symptoms, and your overall treatment plan.
-
At 100 mg/mL, 1 cc per week equals 100 mg.
-
At 200 mg/mL, 1 cc per week equals 200 mg.
For some individuals, a weekly exposure in that general range might end up being appropriate; for others, it may be too high or too low. Men starting with very low baseline levels may require adjustments beyond 125 mg of testosterone a week, 140 mg of testosterone a week, or 150mg testosterone per week, while others may do best at lower totals.
Will One Shot or One Dose of Testosterone Do Anything?
A single injection can temporarily raise blood levels, and some men may notice short-term changes in mood or libido. However, the outcomes most people care about—better energy, more stable mood, improved body composition—are usually linked to consistent, properly monitored therapy over time, not a one-time dose.
In other words, an isolated once-off testosterone shot is unlikely to correct a long-standing low-testosterone problem. That’s why guideline-based care emphasizes steady weekly testosterone injections (or another appropriate schedule), follow-up labs, and regular conversations between patient and clinician.
Injection Frequency: Weekly, Biweekly, or Monthly?
Another set of common search queries revolves around TRT weekly or biweekly, once a week testosterone injection, or a once a month testosterone shot.
-
Weekly or split-weekly dosing is often used to smooth out peaks and troughs, helping testosterone levels stay more stable.
-
Biweekly dosing (every two weeks) can still be used but may create more noticeable highs and lows for some men.
-
Once-a-month testosterone shots tend to produce the widest variability in levels and are less commonly chosen when precise symptom control is a priority.
So when someone asks how much test per week or how many cc of testosterone a week is “best,” they’re really asking about total mg per week and how that dose is spaced out over time to balance convenience, stability, and side-effects.
High-Dose Numbers: 400 mg and 1 Gram Per Week
On forums and social media, you’ll frequently see phrases like:
-
400 mg testosterone per week results
-
1 gram of testosterone per week
-
2 cc of testosterone a week on very concentrated products
It is important to understand that these patterns usually reflect performance-enhancing or bodybuilding cycles, not physiologic testosterone replacement therapy.
In evidence-based TRT, the goal is to normalize testosterone levels for men with documented deficiency, not to push levels far above the normal range. Chasing 400 mg testosterone per week results or 1 gram of testosterone per week is very different from guideline-driven care and may carry significantly higher risk.
If you run into these numbers online, treat them as examples of non-medical use rather than targets to copy.
Finding Thoughtful Care in Arizona (and Beyond)
If you’re exploring TRT in Arizona or any other state, it can be tempting to walk into an appointment already fixed on a dose like 150mg testosterone per week or “1 cc per week” based on what you’ve read online.
A safer, more effective approach is to work with a clinic or telemedicine provider that:
-
Confirms your diagnosis with appropriate blood work and symptom assessment
-
Clearly explains the difference between cc and mg, including how many milligrams in a cc of testosterone for your specific vial
-
Helps you understand exactly how many mg is 1 cc of test, and what your total weekly testosterone injections represent in mg
-
Reviews potential risks, benefits, and monitoring before starting or adjusting treatment
-
Operates in compliance with state telemedicine laws, controlled-substance regulations, FTC advertising rules, and HIPAA privacy standards
Key Takeaway: Dose Decisions Aren’t One-Size-Fits-All
Ultimately, there is no one-size-fits-all answer to how much TRT per week or whether 1 cc of testosterone a week is “enough.” Any decision about dose, frequency, or formulation should be grounded in objective lab testing, a careful review of your symptoms and medical history, and an ongoing relationship with a qualified clinician. Use articles like this to ask better questions—not to self-prescribe-and always rely on professional medical guidance when it comes to starting, adjusting, or stopping testosterone therapy.
