High blood pressure is one of the most common effects of anabolic steroid use and one of the easiest to measure. A good home cuff costs less than a month of supplements, takes two minutes a day and gives you more useful information than almost anything else. This guide explains why pressure rises, how to measure it properly and what to do with the numbers.
- Steroids raise blood pressure through water and salt retention, thicker blood and changes in blood vessel walls.
- Home readings, taken properly over a week, are more reliable than a single reading in a clinic.
- Hypertension Canada considers a home average of 135/85 or higher to be high.
- Persistently high readings are a reason to stop and see a doctor, not to add more supplements.
Why steroids raise blood pressure
Water and salt
Compounds that convert to estrogen, or act like it, increase sodium and water retention. More fluid in the circulation means higher pressure. This is why Dianabol and Anadrol often cause sharp rises.
Thicker blood
Androgens increase red blood cell production. As hematocrit rises, the blood becomes more viscous and the heart has to push harder.
Blood vessel changes
Steroids can make arteries stiffer and affect the systems that let them relax. Over time that raises resting pressure even without water retention.
Add-ons
Stimulants, pre-workouts, decongestants, liquorice, high salt intake, poor sleep and alcohol all push pressure up further.
How to measure at home
- Use a validated upper-arm cuff in the right size. Muscular arms often need a large cuff; a cuff that is too small reads falsely high.
- Avoid caffeine, smoking and exercise for 30 minutes beforehand, and empty your bladder.
- Sit with your back supported, feet flat and arm resting at heart height. Rest quietly for five minutes.
- Take two readings a minute apart, morning and evening, for seven days.
- Ignore the first day and average the rest. That average is your real number.
Measure around the middle of your upper arm and check the range printed on the cuff. Large and extra-large cuffs are widely available in Canadian pharmacies.
What the numbers mean
| Home average | What it suggests |
|---|---|
| Below 120/80 | Normal |
| 120 to 134 / 80 to 84 | Higher than ideal; keep monitoring and work on lifestyle |
| 135/85 or higher | High; see a doctor |
| 180/110 or higher | Very high; seek care promptly, urgently if you have symptoms |
A very high reading with chest pain, shortness of breath, a severe headache, confusion, vision changes or weakness on one side needs 911.
Bringing it down
- Remove the cause: stopping oral steroids or compounds that cause heavy water retention often lowers pressure within weeks.
- Salt: processed and restaurant food contain most of the salt we eat; cutting back helps quickly.
- Potassium-rich foods: vegetables, fruit and legumes help balance sodium if your kidneys are healthy.
- Cardio: regular moderate cardio lowers resting pressure.
- Sleep: short or broken sleep raises pressure; snoring and daytime sleepiness may point to sleep apnea.
- Limit stimulants and alcohol.
Some people need medication. A doctor will choose based on your situation; telling them about steroid use helps them pick the right option.
Why it matters long term
High blood pressure damages arteries, the heart, kidneys and eyes over time, and it is a leading risk factor for strokes and heart attacks. See our guides to heart health and kidney health.

Frequently asked questions
How often should I check my blood pressure?
Take a full seven-day set before starting anything, then at least weekly while using it, and again for a week a month after stopping.
Are wrist cuffs accurate?
Upper-arm cuffs are more reliable. Wrist cuffs are very sensitive to arm position.
Why is my reading higher at the clinic?
Many people read higher in a clinic because of stress. Home averages give a truer picture, which is why guidelines value them.
