- Canada’s Guidance on Alcohol and Health (2023) says 2 or fewer standard drinks a week is low risk; 7 or more carries increasingly high risk.
- Alcohol blunts muscle building: drinking after training reduced muscle protein synthesis in research, even with protein.
- Alcohol plus oral steroids compounds liver strain; alcohol also raises blood pressure.
- A few drinks occasionally won’t ruin progress, but regular heavy drinking will.
Alcohol is part of social life in Canada, and most lifters drink at least sometimes. This guide explains what alcohol actually does to muscle, hormones and recovery, why it’s riskier for people using steroids, and how Canada’s updated alcohol guidance applies.
Canada’s alcohol guidance
In 2023 the Canadian Centre on Substance Use and Addiction published Canada’s Guidance on Alcohol and Health. It describes risk as a continuum:
| Standard drinks per week | Risk |
|---|---|
| 0 | No alcohol-related risk |
| 2 or fewer | Low |
| 3 to 6 | Moderate |
| 7 or more | Increasingly high |
A standard drink in Canada is 341 ml of 5% beer, 142 ml of 12% wine, or 43 ml of 40% spirits.
Alcohol and muscle
- Muscle protein synthesis: in a study of athletes drinking after resistance exercise, muscle protein synthesis fell substantially, even when protein was consumed alongside.
- Testosterone: heavy drinking lowers testosterone; occasional moderate drinking has small effects.
- Sleep: alcohol helps you fall asleep but fragments sleep later in the night, hurting recovery.
- Calories: alcohol has 7 calories per gram and often comes with extra food, which matters on a cut.
Alcohol and steroids
Liver
Oral 17-alpha-alkylated steroids strain the liver; alcohol adds to it. Avoiding alcohol entirely while using orals is the simplest protection. See our liver guide.
Blood pressure and heart
Regular drinking raises blood pressure, on top of steroid effects. Heavy drinking also raises triglycerides and the risk of irregular heart rhythms.
Mood and judgement
Alcohol lowers inhibitions. Combined with irritability or aggression from some steroids, the risk of conflict and poor decisions rises.
Practical approach
- Avoid alcohol on oral steroids
- Don’t drink in the hours after training
- Count drinks against the weekly guidance
- Alternate with water and eat beforehand
- Choose lower-alcohol options; Canada has a wide range of non-alcoholic beers
If drinking feels hard to control, provincial support lines and your family doctor can help; see our harm reduction guide for numbers.
Frequently asked questions
Can I drink alcohol on a steroid cycle?
Occasional moderate drinking on injectables is less risky than drinking on oral steroids, which already strain the liver. Less is better either way.
Does alcohol kill gains?
Regular or heavy drinking reduces muscle protein synthesis, sleep quality and testosterone. Occasional drinks have smaller effects.
What is a standard drink in Canada?
341 ml of 5% beer, 142 ml of 12% wine, or 43 ml of 40% spirits.
How much alcohol is low risk in Canada?
Canada’s 2023 guidance says 2 or fewer standard drinks a week is low risk.
This article is general information for adults in Canada, not medical advice. Talk to a doctor or pharmacist before using any prescription drug, anabolic steroid or research compound, and get bloodwork done. If you’re in crisis, call or text 9-8-8 (Suicide Crisis Helpline) any time.
