HelloPharmacist Scorecard of RAD-Mass by Vintage Muscle

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
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.

RAD-Mass is a liquid formula with a single active ingredient: 4-androsterone, a prohormone your body theoretically converts to testosterone and other male hormones. The product also contains propylene glycol, ethanol, and natural flavors 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 4-androsterone product and its label doesn't state a use — see 4-androsterone'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.

We don't have effectiveness data on file for 4-androsterone, so we can't tell you whether this product delivers on its claims.

The evidence, ingredient by ingredient 4-androsterone

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • 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.

Here's the honest part: safety data on 4-androsterone isn't well studied. Because it's converted to hormones in your body, there's concern it could cause serious side effects similar to anabolic steroids — including stroke, kidney failure, and liver injury.

Prohormones can also disrupt your hormone balance, strain your liver, and affect your cholesterol levels. Don't use this product if you're pregnant — androgenic hormones can harm a developing baby.

If you're nursing, the hormonal effects on your infant aren't known but could potentially be harmful, so avoid it. Talk with your doctor or pharmacist before starting if you have any liver, kidney, or heart concerns.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — 4-androsterone.
  • The most serious interaction on file is rated Moderate.
  • For scale: 8 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you're taking testosterone (as a medication or supplement), double-check with your pharmacist or doctor before adding this product — there's a Moderate interaction risk. We have no documented interactions with other medications, but that's not a guarantee none exist.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a single-ingredient prohormone product with very limited safety data and theoretical risks of serious side effects. If you take testosterone or any other medication, check it against the interaction tool before you consider using it.

Your pharmacist or doctor can help you weigh whether this is right for your situation.

RAD-Mass by Vintage Muscle: Common Questions

Does RAD-Mass by Vintage Muscle interact with any medications?
Yes. Based on its ingredients, RAD-Mass has a known interaction with 8 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
RAD-Mass contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is 4-androsterone and what's it supposed to do?
4-Androsterone is a prohormone — a compound your body is theorized to convert into testosterone and related male hormones. Manufacturers market it for muscle building and athletic performance, but we don't have effectiveness data to confirm whether it works.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advises against use during pregnancy because androgenic hormones can harm a developing baby. If you're nursing, the hormonal effects on your infant aren't known but could potentially be harmful, so avoid it as well. Talk with your doctor if you have questions.
What are the side effects I should watch for?
We don't have detailed side-effect data, but because 4-androsterone is theorized to convert to anabolic compounds, there's concern it could cause serious effects similar to anabolic steroids — including stroke, kidney failure, and liver injury. It may also disrupt your hormones, strain your liver, and affect your cholesterol. If you experience mood changes, chest pain, swelling, or yellowing of skin or eyes, stop and contact your doctor.
Is this safe for long-term use?
Safety isn't well studied, especially over time. Because prohormones can strain your liver and disrupt your hormones, it's something to discuss with your doctor or pharmacist before starting — especially if you have liver, kidney, or heart issues.
What's in this besides the active ingredient?
The product contains propylene glycol, ethanol (alcohol), and natural flavors as inactive ingredients to deliver the liquid formula.
