What the research says
1 study reviewedSupporting (1)
Off-label testosterone therapy is associated with higher long-term cardiovascular risk in men
Cohort StudyHuman2026
This study found that men who took testosterone without having a diagnosed low testosterone level had a much higher chance of having heart attacks, strokes, or dying compared to men who took it because they were truly low in testosterone. So, taking testosterone when you don’t need it may be risky for your heart.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
