HelloPharmacist Scorecard of M-Sten RX by IronMagLabs
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
M-Sten RX contains one active ingredient: methylstenbolone (2,17a-dimethyl-17b-hydroxy-5a-androst-1-en-3-one), a synthetic anabolic steroid. The capsule also holds inactive ingredients — rice flour, gelatin, magnesium stearate, stearic acid, and silica — which serve as fillers and binders.
Does it work?
Insufficient evidence
The evidence we hold does not establish whether methylstenbolone works for athletic performance, muscle strength, erectile dysfunction, sexual arousal, or obesity — the rating is insufficient reliable evidence to rate for all of these. If you're considering this product for any of these goals, you'll want to discuss the actual evidence with your doctor, since both safety and benefit are unclear.
How safe is it?
Well-documented data
Methylstenbolone is possibly unsafe when taken by mouth. As an anabolic androgenic steroid, it carries concern for serious side effects including heart disease and liver injury.
A documented case reported jaundice, elevated liver enzymes, dark urine, and itching in a young man using a methylstenbolone product at recommended doses for about a month — liver function recovered after stopping, but the risk is established. The safety data advises against this ingredient during pregnancy and breastfeeding because of potential harm to the developing baby or nursing infant.
Meds to double-check
No known interactions
No interactions are documented in our data for methylstenbolone. However, if you take any prescription medications, confirm with your doctor or pharmacist before starting this product — they can review your specific drugs and assess risk.
The bottom line
Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
This product contains an unapproved synthetic anabolic steroid with documented risk of serious liver and heart harm at recommended doses. The evidence does not show it works for its claimed purposes.
If you're thinking about taking it, talk with your doctor first — they can discuss whether the risks are acceptable for your individual situation and what safer alternatives might exist.
