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 7 of its 7 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

GH Max contains seven active ingredients. L-Glutamine, L-Arginine Alpha-Ketoglutarate, and L-Ornithine HCl are amino acids — building blocks your body uses for muscle, immune function, and recovery.

The product also includes Vitamin B6, a B vitamin involved in energy and nerve function; Gamma Oryzanol, a plant compound from rice bran; Phytosterols, plant-based compounds; and Carnitine, which plays a role in how your cells produce energy. The tablet also contains inactive ingredients (fillers and binders) including dicalcium phosphate, whey, stearic acid, magnesium stearate, and pharmaceutical glaze.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: strength and power for elite athletes.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Muscle strength, Postoperative recovery, Muscle hypertrophy, Anabolic support — and 2 related terms.
  • The strongest evidence on file: Ornithine is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Glutamine is rated "Possibly Effective" for Postoperative recovery.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.

The evidence for this product's individual ingredients is mixed. L-Glutamine is effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, postoperative recovery, and critical illness.

L-Arginine has no established effectiveness ratings in our data. L-Ornithine is possibly effective for athletic performance but has insufficient evidence for dry skin, insomnia, and gum disease.

Vitamin B6 is effective for certain types of anemia, vitamin B6 deficiency, and a rare form of epilepsy, and likely effective for high homocysteine levels; it's possibly effective for pregnancy-related nausea. Gamma Oryzanol is possibly effective for high cholesterol but has insufficient evidence for athletic performance or eczema.

We could not evaluate Phytosterols or Carnitine. The product hasn't been tested as a combined formula, so we don't know how these ingredients work together.

The evidence, ingredient by ingredient Glutamine L-arginine Ornithine Vitamin B6 Gamma-oryzanol

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 3 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated at standard doses. L-Glutamine commonly causes belching, bloating, constipation, diarrhea, flatulence, nausea, and headache; rare cases of mania have been reported in people with bipolar disorder.

L-Arginine may cause abdominal pain, bloating, nausea, diarrhea, headache, insomnia, and flushing. Vitamin B6 at routine doses is well tolerated, but high doses taken long-term can damage nerves (sensory neuropathy), especially above 1,000 mg daily.

L-Ornithine's long-term safety isn't well studied. For pregnancy, L-Glutamine is likely safe, but L-Ornithine, Gamma Oryzanol, and Carnitine have insufficient safety data — the product advises avoiding them unless your doctor recommends it.

For breastfeeding, L-Glutamine data is limited; L-Ornithine, Gamma Oryzanol, and Carnitine should be avoided unless advised by a clinician. Anyone with kidney or liver disease should use L-Glutamine only under medical supervision.

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?
  • 3 of the 5 matched ingredients can interact with medications — L-arginine, Glutamine, Vitamin B6.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; diabetes medications; Parkinson's medications.
  • For scale: 479 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 GH Max, double-check with your pharmacist if you take: blood pressure medications (antihypertensives, ACE inhibitors, ARBs), potassium-sparing diuretics, blood thinners or antiplatelet drugs, diabetes medications, heart drugs like isoproterenol or sildenafil, or seizure medications (phenobarbital or phenytoin). These are where the Moderate-severity risks lie.

Vitamin B6 also interacts with amiodarone and may affect levodopa if you're not taking it with carbidopa.

The bottom line

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

GH Max is marketed for muscle and athletic support, but the evidence is strongest only for L-Glutamine in specific conditions like sickle cell disease. If you take blood pressure medicine, diabetes medication, blood thinners, seizure drugs, or heart medications, check your exact prescriptions with our tool before starting this product — L-Arginine and Vitamin B6 pose real interaction risks.

Talk to your pharmacist or doctor, especially if you have kidney or liver disease or are pregnant or breastfeeding.

For each ingredient in GH Max with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

L-Arginine Alpha-Ketoglutarate9 drug types · 403 drugs

Ace Inhibitors (Aceis)

Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.

Likelihood Probable Evidence D
Isoproterenol (Isuprel)

Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

Likelihood Possible Evidence D
Testosterone

Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.

Likelihood Possible Evidence D

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

Likelihood Unlikely Evidence D

L-Glutamine1 drug type · 50 drugs

Anticonvulsants

Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.

GH Max by Universal: Common Questions

Does GH Max by Universal interact with any medications?
Yes. Based on its ingredients, GH Max has a known interaction with 479 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
GH Max contains 7 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 L-Glutamine safe if I have kidney disease?
L-Glutamine is generally well tolerated, but people with kidney or liver disease should use it only under medical supervision. Talk to your doctor or pharmacist before starting this product if you have either condition.
Will this product help me build muscle or improve athletic performance?
L-Ornithine is possibly effective for athletic performance, but the evidence isn't strong. L-Glutamine and the other ingredients haven't been established as effective for athletic performance specifically. If that's your goal, you'd want to discuss realistic expectations with your pharmacist.
Can I take this while pregnant?
L-Glutamine is likely safe in pregnancy, but L-Ornithine, Gamma Oryzanol, and Carnitine don't have enough safety data — the product advises avoiding them unless your doctor recommends it. Talk to your doctor or pharmacist about whether GH Max is right for you.
What are the most common side effects from L-Glutamine?
The most common are belching, bloating, constipation, diarrhea, flatulence, nausea, headache, and cough. These tend to be mild and often go away on their own.
Is Vitamin B6 in this product safe if I'm taking high doses?
The amount of vitamin B6 in a typical supplement like this is generally safe, but avoid high doses (over 1,000 mg daily) long-term — they can damage nerves. Stick to your supplement's label dose unless your doctor says otherwise.
Why should I check my blood pressure medications before taking this?
L-Arginine Alpha-Ketoglutarate can lower blood pressure and raise potassium levels, which may add to the effect of your blood pressure medicine or potassium-sparing diuretics and increase the risk of low blood pressure or high potassium. Your pharmacist needs to see your exact medication to assess the risk.
