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.

Andar S4 contains one active ingredient: andarine, a selective androgen receptor modulator (a type of compound designed to bind to androgen receptors in the body). The capsules also contain inactive ingredients — rice flour, magnesium stearate, and gelatin — which serve as fillers and binding agents.

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 Andarine product and its label doesn't state a use — see Andarine'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.

We hold no effectiveness ratings for andarine in our data. The evidence supporting its use has not been established in the information available to us.

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.

Andarine is an unapproved drug with unknown human safety and is not a legal supplement. The FDA has warned that selective androgen receptor modulators like andarine could potentially increase the risk of heart attack and stroke.

Additionally, there's a theoretical risk of myocardial infarction, stroke, and liver toxicity, though no thorough safety evaluations of andarine have been conducted in humans. Andarine is unsafe during pregnancy and should be avoided — it is a hormone-affecting drug and has no established human safety data in pregnancy or breastfeeding.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Andarine.
  • The most serious interaction on file is rated Moderate.
  • For scale: 9 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you're taking any androgens (male hormones or related drugs), check with your doctor or pharmacist before starting andarine — the combination carries a Moderate risk of increased androgenic side effects. However, the bigger issue is that andarine itself is unapproved and not a legal dietary supplement, with unknown human safety and potential risks flagged by the FDA.
