From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

D-Zine contains one active ingredient: dymethazine, a designer anabolic steroid — a synthetic compound designed to mimic testosterone and boost muscle and strength. The product also includes rice flour and gelatin as inactive ingredients.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Dymethazine product and its label doesn't state a use — see Dymethazine's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for dymethazine's effectiveness is not established in our data. It's marketed for athletic performance, muscle strength, erectile function, sexual arousal, and weight loss, but we hold insufficient reliable evidence to rate it for any of those uses.

How safe is it?

Safety Information · database check
Well characterized

  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Dymethazine is a designer anabolic steroid with serious safety concerns. It's possibly unsafe when taken by mouth and carries risk of stroke, kidney failure, and liver injury.

There's a documented case of severe liver damage (cholestatic jaundice with elevated liver enzymes, dark urine, and clay-colored stools) in a 26-year-old man using a product containing dymethazine at standard doses for about a month; liver function gradually improved after he stopped. The safety data advises against use during pregnancy and breastfeeding.

Anabolic steroids can harm a developing baby and pose risk while nursing.
