First and foremost: checking Raptor against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

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.
What’s inside
Full disclosure
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
No known interactions
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.
