HelloPharmacist Scorecard of Raptor by Muscle House

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Raptor contains two active anabolic steroid ingredients: methylstenbolone and 17 beta-hydroxy 2 alpha,17beta-dimethyl 5 alpha-androstan 3-one azine. These are synthetic compounds designed to mimic testosterone and promote muscle growth.

The product also contains two inactive ingredients — magnesium stearate and silicon dioxide — which are fillers and flow agents.

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, Muscle strength, Exercise-induced muscle damage, 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 for methylstenbolone in athletic performance, muscle strength, erectile dysfunction, sexual arousal, and weight loss is insufficient to rate — there isn't reliable research we hold to support claims for any of these uses. The same is true for the second ingredient — we have no effectiveness data on file for it.

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 classified as possibly unsafe when taken by mouth. As an anabolic androgenic steroid, it carries a serious risk of heart disease and liver injury.

There is a documented case of liver inflammation (cholestatic jaundice) with elevated liver enzymes, dark urine, clay-colored stools, and itching in a 26-year-old male who used a product containing methylstenbolone at the manufacturer's recommended dose for up to one month; liver function gradually improved after he stopped. The product must be avoided during pregnancy and while breastfeeding because of the risk of harm to a developing baby or nursing infant.

We don't hold pregnancy or breastfeeding safety information for the second ingredient.

Side effects, ingredient by ingredient Methylstenbolone

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. However, because we don't hold interaction data for one of the two active ingredients, you should still review your exact medications with your doctor or pharmacist before taking this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

This product contains unapproved synthetic anabolic steroids with no established reliable evidence for the claims made about them. The documented risk of serious liver and heart harm, combined with hormonal effects and potential harm in pregnancy and breastfeeding, makes this a product to discuss carefully with your doctor or pharmacist before considering — especially if you have any liver, heart, or hormonal condition, or if you're planning to become pregnant or are breastfeeding.

Does Raptor by Muscle House interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Raptor. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Raptor contains 2 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.
Can I use Raptor if I'm pregnant or breastfeeding?
No. Methylstenbolone must be avoided during pregnancy and breastfeeding because of the risk of serious harm to a developing baby or nursing infant. If you're planning to become pregnant or are currently breastfeeding, talk with your doctor or pharmacist about this product.
Does this product have any documented side effects?
Yes. The main active ingredient, methylstenbolone, is possibly unsafe and carries serious risk of heart disease and liver injury. There's a documented case of a young man who developed liver inflammation (jaundice) with elevated enzymes, dark urine, and itching after using a product containing methylstenbolone at the recommended dose for about a month — though his liver function improved after he stopped.
Is there solid research showing this product works for muscle building?
No. The evidence for methylstenbolone in muscle strength and athletic performance is insufficient to rate — meaning there isn't reliable research we hold to back up those claims. We also have no effectiveness data on file for the second active ingredient.
