HelloPharmacist Scorecard of Ultra-Sten 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.

From our pharmacy team — supplement deep dive

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.

Ultra-Sten contains one active ingredient: methylstenbolone, a synthetic anabolic steroid. The capsule also holds rice flour and gelatin as inactive ingredients.

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 Methylstenbolone's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: muscle building and strength gains.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Muscle strength, Body composition, Power output.
  • The closest evidence on file: Methylstenbolone is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Methylstenbolone is rated "Insufficient Reliable Evidence To Rate" for Muscle strength, Exercise-induced muscle damage.

The evidence we hold does not establish that methylstenbolone works for athletic performance, muscle strength, erectile dysfunction, sexual arousal, or weight loss — all five uses show insufficient reliable evidence to rate. That means the science hasn't clearly shown benefit for any of these claims.

The evidence, ingredient by ingredient Methylstenbolone

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.

Methylstenbolone is rated possibly unsafe. As an anabolic androgenic steroid, it carries concern for serious side effects including heart disease and liver injury.

One documented case reported severe liver damage (cholestatic jaundice with dark urine, pale stools, and itching) in a 26-year-old taking a product containing this ingredient at recommended doses for about a month; liver enzymes only gradually improved after he stopped. This ingredient must not be used during pregnancy — the safety data advises against it because anabolic steroids can harm a developing baby.

It should also not be used while breastfeeding due to potential harm to the infant.

Why this rating?

No interactions are documented in our data for methylstenbolone. However, because this is an unapproved anabolic steroid with serious safety concerns, discuss this product with your pharmacist or doctor before you start, regardless of what medications you take.

Ultra-Sten by Hardcore Formulations: Common Questions

Does Ultra-Sten by Hardcore Formulations interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Ultra-Sten. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Ultra-Sten 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.
Does methylstenbolone actually work for muscle building or athletic performance?
The evidence we hold doesn't establish that it works for muscle strength, athletic performance, erectile dysfunction, sexual arousal, or weight loss — all rated as having insufficient reliable evidence. The science hasn't clearly shown benefit yet.
What are the side effects I should know about?
Methylstenbolone is considered possibly unsafe and is linked to serious concern for heart disease and liver injury. There's a documented case of severe liver damage (jaundice with dark urine and pale stools) in someone taking a product containing this ingredient at the recommended dose for about a month.
Can I take this while pregnant or breastfeeding?
No — the safety data advises against it. Anabolic steroids can harm a developing baby, and this ingredient should not be used while breastfeeding because of potential harm to the infant.
Is methylstenbolone approved by the FDA?
No, it is an unapproved synthetic anabolic steroid. This is a major red flag for safety — unapproved means the ingredient hasn't gone through FDA review for safety and effectiveness.
