- TRT is legal, prescribed treatment for men with symptoms of low testosterone confirmed by blood tests.
- Diagnosis needs both symptoms and at least two morning blood tests, reported in Canada in nmol/L.
- Canadian options include injections, gels, oral capsules and Natesto, a nasal gel developed in Canada.
- TRT is usually long-term. It suppresses natural production and fertility, so it isn’t a short fix, and it isn’t the same as a steroid cycle.
Low testosterone is common, under-diagnosed and treatable. If you’re a Canadian man with low energy, low libido and loss of muscle, testosterone replacement therapy (TRT) might help, through a doctor, legally, with monitoring. This guide explains how diagnosis works in Canada, the treatment options, what it costs, and how TRT differs from using steroids on your own.
Symptoms of low testosterone
- Low sex drive and fewer morning erections
- Erectile dysfunction
- Fatigue and low motivation
- Low mood or irritability
- Loss of muscle and strength, more body fat
- Reduced body hair, hot flashes, low bone density in more severe cases
These symptoms overlap with poor sleep, depression, obesity, thyroid problems and other conditions, which is why blood tests matter.
How diagnosis works in Canada
- See your family doctor, a walk-in clinic or a telehealth service. Describe your symptoms.
- Get two morning blood tests on different days, usually before 10 AM when testosterone is highest. Canadian labs report total testosterone in nmol/L.
- Investigate causes. Your doctor may check LH, FSH, prolactin, iron, thyroid, blood sugar and a complete blood count to find out why it’s low.
There’s no single cut-off everyone agrees on. Many clinicians treat consistently low levels (often below roughly 8 to 12 nmol/L, depending on the guideline and lab) when symptoms are present. Lab reference ranges are printed on your results.
Before testing: sleep normally, don’t test when you’re ill, and tell your doctor about any steroids or SARMs you’ve used. Past use is a common cause of low testosterone.
Treatment options in Canada
| Form | How it’s used | Pros | Cons |
|---|---|---|---|
| Injections (enanthate, cypionate) | Every 1 to 2 weeks, or smaller weekly doses | Cheapest, reliable | Needles; peaks and troughs with longer gaps |
| Gels (e.g. AndroGel, Testim) | Daily on skin | Steady levels, no needles | Costlier; risk of transfer to partners and children |
| Oral testosterone undecanoate | Capsules with meals | No needles, no transfer | Absorption varies; multiple daily doses |
| Natesto (nasal) | Nasal gel, several times a day | Short-acting, may affect fertility less | Frequent dosing |
Natesto was developed by a Canadian company and is one of the few options studied for its smaller effect on sperm production.
What it costs
Injectable testosterone is usually the cheapest form; gels cost considerably more per month. Coverage varies: provincial drug plans may cover some forms for people who qualify, and most private insurance covers testosterone with a prescription. Ask your pharmacist what your plan covers before choosing a form.
Monitoring
- Testosterone at about 3 and 6 months, then yearly, aiming for the normal range
- Hematocrit, because testosterone raises red blood cells; above about 54% usually means a dose change
- PSA and prostate checks in men over 40
- Blood pressure, lipids and symptoms
Fertility
TRT suppresses LH and FSH, which lowers sperm production, sometimes to zero. If you want children, tell your doctor before starting; there are fertility-sparing approaches. See our fertility guide.
TRT vs a steroid cycle vs “cruising”
| TRT | Steroid cycle | “Blast and cruise” | |
|---|---|---|---|
| Goal | Normal testosterone levels | Above-normal levels for performance | Never come off |
| Supervision | Doctor, regular bloodwork | Usually none | Usually none |
| Legal route | Prescription | Personal possession, not prescribed | Personal possession, not prescribed |
| Natural production | Suppressed long-term | Suppressed, then recovers | Suppressed indefinitely |
Staying on testosterone between cycles (“bridging” or “cruising”) means permanently relying on outside testosterone, without the diagnosis or monitoring of real TRT. If you’ve used steroids and your levels haven’t recovered, the better route is a doctor: post-steroid low testosterone is a recognized cause of hypogonadism. Our PCT guide covers recovery.
Legal status
Testosterone is a prescription drug in Canada and an anabolic steroid under Schedule IV of the Controlled Drugs and Substances Act. With a prescription, it’s entirely legal; without one, personal possession isn’t an offence, while trafficking, importing and exporting without authorization are.
Frequently asked questions
How do I get TRT in Canada?
See a family doctor, walk-in clinic or telehealth service with your symptoms, then get two morning blood tests. If testosterone is consistently low and you have symptoms, they can prescribe it.
What testosterone level is considered low in Canada?
Labs report in nmol/L. Many clinicians consider levels below roughly 8 to 12 nmol/L low when symptoms are present, but cut-offs vary.
Is TRT covered by OHIP or provincial plans?
Doctor visits and lab tests are generally covered; drug coverage depends on your provincial plan and private insurance. Ask your pharmacist.
Is TRT for life?
Often, yes. Stopping usually returns you to low levels, and natural production may take time to recover.
Can I get TRT after using steroids?
Yes, if your testosterone stays low with symptoms. Tell your doctor about past use; it helps them find the cause.
