HelloPharmacist Scorecard of S-23 by Swoll Mafia
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
This product contains one active ingredient: Cyanobol, the experimental compound S-23. The product also includes creatine as an inactive ingredient.
Does it work?
Couldn't assess
The evidence we hold for Cyanobol and athletic performance, muscle strength, cachexia (severe muscle wasting), and muscular dystrophy is insufficient to rate it. The same applies to its use for breast cancer.
In short, we don't have reliable data showing whether this ingredient works for any of these purposes.
How safe is it?
Some data gaps
Cyanobol is an unapproved experimental drug with no human safety data and known hormonal risks. The safety data advises against using it during pregnancy — it alters hormones and may harm a developing baby.
It's also hormonally active, so safety is unknown while breastfeeding; avoid it then too. Adverse effects in trials aren't documented in our data, but that's because human trial data itself doesn't exist for an experimental compound.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. However, because Cyanobol is an unapproved experimental compound with unknown effects on the body, talk with your doctor or pharmacist before starting it if you take any medications.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.
S-23 is an unapproved experimental drug with no established safety record in humans. If you're considering it, talk with your doctor first — this isn't a conventional supplement, and they need to know you're thinking about trying it.
Definitely avoid it if you're pregnant, planning pregnancy, or breastfeeding.
