HelloPharmacist Scorecard of GH Factor by Beverly International

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 Jul 11, 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.

GH Factor contains 2 active ingredients: arginine pyroglutamate and lysine monohydrochloride (a form of the amino acid lysine). These are amino acids — building blocks your body uses for various functions.

The capsules also contain inactive ingredients: gelatin, magnesium stearate, and microcrystalline cellulose, which are common excipients that help form and stabilize the supplement.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Lysine's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: physique revitalization for regular exercisers.
  • We looked for evidence on: Athletic performance, Muscle strength, Muscle growth, Body composition, Exercise recovery.
  • The closest evidence on file: Lysine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Lysine is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

Lysine is possibly effective for herpes labialis (cold sores) based on the evidence we have. For other uses in this product — child growth, pressure ulcers, and diabetic foot ulcers — the evidence isn't established enough to rate.

We don't hold effectiveness data for arginine pyroglutamate.

The evidence, ingredient by ingredient Lysine

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.

Lysine is generally well tolerated at typical doses. Some people report abdominal pain, diarrhea, or indigestion, especially at high amounts — long-term safety at high doses isn't well studied.

There's one case report of oral lysine linked to a kidney condition, though this is rare. For pregnancy and breastfeeding, there isn't enough reliable data on supplement use to know either way, so check with your doctor or pharmacist first before taking this if you're pregnant or nursing.

Side effects, ingredient by ingredient Lysine

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Lysine.
  • The most serious interaction on file is rated Minor.
  • For scale: 1 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 take a 5-HT4 agonist, check with your pharmacist before starting this product — lysine may reduce how well it works. Arginine pyroglutamate could not be checked, so mention it to us if you're on any prescription medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

GH Factor may interest people looking for lysine's cold sore support. If you take a 5-HT4 agonist (a less common medication), you'll want to check with your pharmacist first.

Otherwise, talk through your medication list with us before starting — especially if you're pregnant, nursing, or prone to stomach upset.

5-Ht4 Agonists

Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.
