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.

Deca-DuraBolin 200 mg contains a single active ingredient: 19-nor-DHEA (19-NorAndrost-4-ene-3b-ol, 17-one Decanoate). It's a prohormone — a compound your body theoretically converts into nandrolone and other male hormones after you take it.

The product also includes several inactive ingredients (microcrystalline cellulose, phosphatidylcholine, cyclodextrin, phytosterols, magnesium stearate, silica, and FD&C Blue #2) that serve as fillers and binders.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see 19-nor-dhea's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: muscle size and strength gains.
  • We looked for evidence on: Athletic performance, Muscle strength, Exercise-induced muscle damage, Lean mass, Body composition.
  • The closest evidence on file: 19-nor-dhea is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: 19-nor-dhea is rated "Insufficient Reliable Evidence To Rate" for Muscle strength, Exercise-induced muscle damage.

The evidence for 19-nor-DHEA isn't established in our data. For athletic performance, muscle strength, obesity, and exercise-induced muscle damage — the purposes this ingredient is often promoted for — we hold insufficient reliable evidence to say whether it actually works.

If you're considering this supplement for any of those reasons, that's important context: we can't confirm it delivers the results the label might suggest.

The evidence, ingredient by ingredient 19-nor-dhea

How safe is it?

Limited data
Safety Information · database check
Limited information

Little studied safety information is available for these ingredients — that is not the same as being safe.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 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.

This is where we need to be straightforward: 19-nor-DHEA is an unproven hormonal prohormone with potential serious side effects and very little safety data. It should not be used during pregnancy or while breastfeeding due to its hormone-altering effects and the lack of reliable safety information.

Beyond those specifics, we don't have documented adverse effects from trials — but the absence of reported side effects doesn't mean the product is without risk, especially given how little it's been studied.

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 — 19-nor-dhea.
  • 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.

Before taking this product, check if you use testosterone or other androgens (male hormones). That's a Moderate interaction.

Because this is a hormone-altering supplement, also discuss it with your pharmacist if you take any heart, kidney, liver, or blood-pressure medications — we haven't documented all possible interactions, and hormonal products can affect how your body processes drugs in unexpected ways.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is limited.

This supplement is a hormone-altering prohormone with weak evidence it works and significant safety concerns. If you take testosterone, other androgens, or any medication affecting your heart, kidneys, or liver, talk to your pharmacist or doctor before starting.

Pregnant or breastfeeding — this one's off the table. For anyone else, the lack of proof and the hormonal nature make it worth a careful conversation with your care team.

Does Deca-DuraBolin 200 mg by HTP Hi-Tech Pharmaceuticals interact with any medications?
Yes. Based on its ingredients, Deca-DuraBolin 200 mg 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?
Deca-DuraBolin 200 mg 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 19-nor-DHEA, and how is it supposed to work?
19-nor-DHEA is a prohormone — a compound your body theoretically converts into nandrolone and related male hormones after you ingest it. It's marketed for muscle building and athletic performance, but we don't have solid evidence it actually works for those claims.
Can I take this if I'm using testosterone or other hormone treatments?
No — combining this supplement with testosterone or similar androgens carries a Moderate interaction risk that can increase mood disturbances and problems with your heart, kidneys, or liver. Talk to your doctor or pharmacist before mixing them.
Is this safe to use during pregnancy or while breastfeeding?
No. The safety data advises against using this product during pregnancy or while breastfeeding due to its hormone-altering effects and lack of reliable safety information.
Does this actually help with muscle strength or athletic performance?
We don't have enough reliable evidence to say it works for muscle strength, athletic performance, exercise-related muscle damage, or obesity. The claims are unproven in our data.
What should I know about safety before I start this?
19-nor-DHEA is an unproven hormonal prohormone with potential serious side effects and very little safety data behind it. That's a significant concern, especially since hormones can have wide-reaching effects on your body.
