Winstrol: Why Some Bodybuilders Favour It—and Reasons for Caution

Winstrol often comes up in bodybuilding discussions about cutting, strength and a leaner appearance. Some users also describe using it during muscle-gaining phases, challenging its reputation as exclusively a “cutting steroid.”

But how much of that reputation comes from personal experience, and what does the evidence actually show?

What Is Winstrol?

Winstrol is a familiar brand name for stanozolol, an anabolic-androgenic steroid derived from dihydrotestosterone, or DHT. The US Anti-Doping Agency’s introduction to stanozolol explains its background and classification.

Why Some Bodybuilders Favour It

The appeal described in bodybuilding accounts centres on strength gains and a leaner appearance, with less of the puffiness users associate with certain other steroids.

The original account also challenges the idea that Winstrol belongs only in a cutting phase. Its author reports finding it useful while trying to gain muscle, with strength improvements they considered comparable to Dianabol.

Those observations are personal reports, not controlled comparisons. They cannot establish that another person will experience the same results or that Winstrol is a better choice for gaining muscle.

Do Anabolic Ratings Tell the Whole Story?

The claim that a higher anabolic rating makes Winstrol superior to Dianabol needs more support than a number on a comparison chart.

A rating alone does not demonstrate greater muscle growth in people, easier retention of gains or a better safety profile. Likewise, the assertion that its gains are “more easily assimilated and kept” should not be presented as an established fact without appropriate human research.

The useful question is whether reliable evidence supports the particular result being claimed.

Why the Health Risks Matter

Winstrol’s reputation for producing a lean appearance can distract from effects that are not visible in the mirror.

Cholesterol changes are documented. A human study comparing stanozolol and testosterone found that oral stanozolol substantially reduced HDL cholesterol and increased LDL cholesterol. These findings challenge the idea that a desirable cosmetic result means a favourable health outcome.

Liver injury is another serious concern. A 2025 study of stanozolol-associated liver injury described 18 affected men who had used it for aesthetic purposes. Jaundice and itching were prominent symptoms. Because this was a study of people who developed injury, it does not establish how frequently injury occurs among all users.

How Should Personal Experiences Be Interpreted?

Personal accounts can raise worthwhile questions, but they cannot reliably separate a drug’s effects from changes in training, nutrition or other substances used at the same time.

Rather than treating a favourable experience as a recommendation to “give it a try,” a more useful discussion examines what changed, what was measured and whether adverse effects occurred.
