HelloPharmacist Scorecard of Sten by Panther Sports Nutrition

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.

Sten contains a single active ingredient: SR9009, also called stenabolic. The product also includes inactive ingredients (rice flour, magnesium stearate, and gelatin), which are fillers and capsule material.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Stenabolic product and its label doesn't state a use — see Stenabolic's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for SR9009 isn't established in the data we hold. Effectiveness for athletic performance, diabetes, and obesity are all rated as having insufficient reliable evidence to rate.

In plain terms, we don't have solid human trial data showing whether this ingredient works for any of these purposes.

The evidence, ingredient by ingredient Stenabolic

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

This is the big one: SR9009 is an untested research chemical with no human safety data, and it's not legal to sell as a supplement. There is no safety information available, which is why it should not be used during pregnancy or while breastfeeding.

The product carries a safety rating of Possibly Unsafe for pregnancy and lactation. Because this ingredient hasn't been studied in people, we can't tell you what side effects to expect or how safe it really is.

Meds to double-check

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

No interactions are documented in our data for SR9009. However, because this ingredient has never been tested in humans, we cannot guarantee there are no interactions.

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.

Sten is a research chemical without human safety data or proven effectiveness. If you're thinking about trying it, talk with your pharmacist or doctor first — especially if you're taking any medications, pregnant, or breastfeeding.

We'd recommend being very cautious here.

Sten by Panther Sports Nutrition: Common Questions

Does Sten by Panther Sports Nutrition interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Sten. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
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.
Is SR9009 legal to sell as a supplement?
No. SR9009 is not legal to sell as a supplement. It's an untested research chemical without human safety data.
Does SR9009 actually help with athletic performance?
The evidence isn't established in our data. We have insufficient reliable evidence to rate whether it works for athletic performance.
Can I take Sten if I'm pregnant?
No. There's no safety information for SR9009 in pregnancy, so it's rated as Possibly Unsafe. You should not use it during pregnancy.
Can I take Sten while breastfeeding?
No. There's no safety information for SR9009 while breastfeeding, so it should not be used.
What are the side effects?
We have no data on side effects because SR9009 hasn't been tested in humans. That's a major red flag — we simply don't know what it might do to you.
