HelloPharmacist Scorecard of 4-Andro Max by Primeval Labs

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.

4-Andro Max contains one active ingredient: 4-androsterone, a prohormone that your body is thought to convert into testosterone and other androgens. The tablet also includes several inactive ingredients—phospholipids, microcrystalline cellulose, dicalcium phosphate, hydroxypropyl beta cyclodextrin, polyvinylpyrrolidone, silica, and magnesium stearate—which help deliver and stabilize the active compound.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: muscle building and strength support.
  • We looked for evidence on: muscle mass, athletic performance, strength.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't have effectiveness data on file for 4-androsterone in our system. The evidence supporting what this ingredient actually does in your body isn't established in the information we hold.

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 what you should know: prohormones can disrupt your hormonal balance, stress your liver, and change your cholesterol levels, and safety hasn't been well studied in real-world use. The concern is real enough that we've flagged theoretical risks of serious side effects—including stroke, kidney failure, and liver damage—similar to those seen with anabolic steroids, though these are based on what we know about how the ingredient might behave, not proven in people.

Don't use this product if you're pregnant—androgenic hormones can harm a developing baby. If you're breastfeeding, avoid it too, because the hormonal effects on a nursing infant aren't known and could be harmful.

If you're thinking about this supplement and either is a possibility for you, talk with your doctor or pharmacist first.

Known Interaction Concern · database check

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.

Check with your pharmacist if you take testosterone or testosterone-related products before starting 4-Andro Max. The combination could amplify testosterone side effects and raise your risk of mood, heart, kidney, or liver problems.

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.

4-Andro Max is a prohormone intended for people interested in hormone-related supplementation, but the safety profile isn't well established and the risks—especially to your liver and heart—are theoretical but serious. If you take testosterone or any hormone-related medication, check it with your pharmacist before you start.

4-Andro Max by Primeval Labs: Common Questions

Does 4-Andro Max by Primeval Labs interact with any medications?
Yes. Based on its ingredients, 4-Andro Max 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?
4-Andro Max 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.
Can I take 4-Andro Max if I'm pregnant or breastfeeding?
No. Androgenic hormones can harm a developing baby, so don't use it during pregnancy. If you're nursing, the hormonal effects on your infant aren't known and could be harmful, so avoid it then too. Talk with your doctor before taking any prohormone supplement if either applies to you.
What are the potential side effects of 4-androsterone?
We don't have detailed adverse effect data from studies, but because 4-androsterone converts into testosterone-like compounds, there's concern it could cause serious effects similar to anabolic steroids—including stroke, kidney failure, and liver injury. The bigger picture: prohormones can disrupt your hormones, strain your liver, and affect cholesterol.
What is 4-androsterone supposed to do?
4-Androsterone is a prohormone that your body is thought to convert into testosterone and other androgens. We don't have established effectiveness data on file for it, so what it actually accomplishes in real use isn't confirmed in our system.
Does 4-Andro Max interact with my medications?
If you take testosterone or testosterone-related products, yes—there's a documented moderate interaction. For your exact medications, use the checker on this page. Because prohormones affect your whole hormone system, it's worth verifying any prescription or supplement you're on.
Why is 4-Andro Max flagged as a safety concern?
Prohormones can disrupt hormones, strain the liver, and shift cholesterol levels, but safety hasn't been well studied. The theoretical risks—stroke, kidney failure, liver damage—are serious enough that this category of supplement deserves caution and a conversation with your pharmacist before you start.
