HelloPharmacist Scorecard of D-Zine by Hardcore Formulations
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
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
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?
Well-documented data
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.
Meds to double-check
No known interactions
No interactions are documented in our data for dymethazine. However, because dymethazine is an anabolic steroid with profound effects on hormones and organs, you should discuss this product with your doctor or pharmacist before taking it — especially if you take any medications.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
D-Zine is a designer anabolic steroid with documented risks of serious liver, kidney, and cardiovascular harm — even at manufacturer-recommended doses. It is not appropriate for pregnancy or breastfeeding.
Given the severity of these safety concerns and the lack of proven effectiveness, most people should avoid this product entirely. If you're considering it, talk with your doctor first.
