HelloPharmacist Scorecard of Mass GH by Olympus UK

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 20, 2026

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Mass GH contains 2 active ingredients: ligandrol (marketed as Legend), a selective androgen receptor modulator (SARM) under investigation for muscle and strength, and Ghar1ne, which we couldn't find detailed information on. The capsules also hold rice flour, magnesium stearate, and gelatin as inactive ingredients.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: muscle building and athletic performance.
  • We looked for evidence on: Athletic performance, Muscle strength, muscle mass, strength gains, body composition.
  • The closest evidence on file: Ligandrol is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Ligandrol is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

The evidence we hold doesn't establish that ligandrol works for athletic performance, muscle strength, cachexia, muscular dystrophy, or breast cancer—the ratings across these uses are insufficient reliable evidence to rate. That means the research backing its use for these purposes hasn't been nailed down yet.

The evidence, ingredient by ingredient Ligandrol

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.

Ligandrol is an unapproved investigational drug, not a legal dietary supplement, and the safety data advises against it in pregnancy and while breastfeeding—it may harm a developing baby and can pass into breast milk. Beyond that, the FDA has warned that ligandrol-containing supplements are associated with liver toxicity, and case reports document liver injury in people who've used it.

One case involved a man who took 10 mg daily for just 2 weeks before developing signs of liver damage. Ligandrol has also been shown to lower HDL cholesterol (the "good" kind) in trial doses as low as 0.3 mg daily.

Side effects, ingredient by ingredient Ligandrol

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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 — Ligandrol.
  • The most serious interaction on file is rated Moderate.
  • For scale: 371 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.

Before taking Mass GH, check with your doctor or pharmacist if you take any hepatotoxic drugs (medications that stress the liver). Ligandrol may add to that risk.

Because ligandrol is not an approved supplement and carries real safety concerns, your own healthcare provider should clear it alongside any other medications you use.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Ligandrol is an unapproved drug with documented liver injury risk and FDA warnings—it's not a standard dietary supplement. If you're considering Mass GH, talk with your doctor or pharmacist first, especially if you have liver disease or take any medication that affects liver function.

They can help you weigh whether this product is right for you.
