HelloPharmacist Scorecard of Abnormal by Blackstone 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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “19-NorDHEA Blend” is a proprietary blend — the label gives one combined amount (50 mg) without saying how much of each component you get.

Abnormal contains 3 active ingredients, all variants of 19-nor-DHEA (a prohormone intended to convert to nandrolone and related compounds in your body). The product also contains several inactive ingredients — microcrystalline cellulose, phosphatidylcholine, hydroxypropyl-beta-cyclodextrin, phytosterol, stearic acid, magnesium stearate, starch, titanium dioxide, silica, and color additives (FD&C Red #40 and FD&C Blue #1) — which are fillers and binders in the tablet.

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 building and strength support.
  • We looked for evidence on: Athletic performance, Muscle strength, body composition, anabolic activity.
  • 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.

The evidence we hold does not establish that 19-nor-DHEA is effective for athletic performance, muscle strength, weight loss, or exercise-induced muscle damage. Every claim carries an Insufficient Reliable Evidence To Rate rating, meaning the data to support its use for these purposes isn't there yet.

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 product carries serious safety red flags. The data advises against use during pregnancy and while breastfeeding due to its hormonal effects and lack of safety information.

Additionally, 19-nor-DHEA is labeled as an unproven hormonal prohormone with potential serious adverse effects and minimal safety data. The product has not been studied extensively, and long-term risks are unknown.

We don't have specific documented adverse effects on file, but the hormonal nature of the ingredient and its intended conversion to androgens means risks to your cardiovascular system, liver, and kidneys are real 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 — 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.

Check before taking this if you're on testosterone or other androgens (male hormones) — Moderate risk of additive effects including mood changes and cardiovascular, kidney, or liver problems. If you take any hormone-related medication, run it through the checker below.

The bottom line

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

This is a hormonal supplement aimed at athletes or people building muscle, but the evidence for it actually working isn't established. If you're on testosterone or any androgen medication, check with your doctor before taking it.

Pregnant people and those breastfeeding should avoid it. Talk to your pharmacist or prescriber about whether this product fits your situation and whether the unproven risks are worth it for you.

Abnormal by Blackstone Labs: Common Questions

Does Abnormal by Blackstone Labs interact with any medications?
Yes. Based on its ingredients, Abnormal 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?
Abnormal contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Does 19-nor-DHEA actually build muscle or improve athletic performance?
There isn't enough reliable evidence in our data to say it does. Every athletic and strength claim for this ingredient is rated Insufficient Reliable Evidence To Rate, meaning the science to back it up isn't established.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advises against using hormone-altering products during pregnancy and while breastfeeding due to hormonal effects and lack of safety information.
What is 19-nor-DHEA, and how is it supposed to work?
It's a prohormone — a compound the body is thought to convert into nandrolone and related androgens (male hormones). The idea is that these converted hormones then support muscle growth and athletic performance, but evidence for that isn't established.
What kind of side effects has this ingredient been documented to cause?
We don't have specific documented adverse effects on file. However, because it's an unproven hormonal prohormone with little safety data, serious risks to your heart, liver, and kidneys are a real concern.
I'm on testosterone therapy. Can I take Abnormal?
You should not take this without talking to your prescriber first. Taking a 19-nor-DHEA product alongside testosterone carries a Moderate risk of additive effects, including mood disturbances and problems with your heart, kidneys, or liver.
