HelloPharmacist Scorecard of High G Hardcare Formulation Muscle Booster by High T

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.

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 3 of its 3 active ingredients.
  • “AlphaSize” is listed as a grouped ingredient — the label gives one combined amount (300 mg) without saying how much of each component you get.
  • “SerinAid” is listed as a grouped ingredient — the label gives one combined amount (200 mg) without saying how much of each component you get.

High G contains three active ingredients: phosphatidylserine, alpha-GPC (L-alpha-glyceryl phosphoryl choline), and an amino acid blend. Phosphatidylserine is a fatty compound thought to support cell membrane function and brain health.

Alpha-GPC is a choline derivative believed to support cognitive function and brain signaling. The amino acid blend's exact composition isn't detailed on file.

The product is filled with standard capsule ingredients — gelatin capsule, cellulose, dicalcium phosphate, magnesium stearate, silica, and color additives (titanium dioxide and FD&C dyes).

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.

Why this rating?
  • The label markets this product for: assist the body in its output of muscle.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle soreness, Muscle strength, Muscle growth, Resistance training recovery.
  • The closest evidence on file: Phosphatidylserine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Phosphatidylserine is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness.

For phosphatidylserine, there's possibly effective evidence for age-related cognitive decline and Alzheimer's disease. For athletic performance, cognitive function generally, ADHD, and dementia, the evidence isn't reliable enough to rate.

For alpha-GPC, there's possibly effective evidence for Alzheimer's disease. For brain tumors, cognitive function, vascular dementia, and stroke, the evidence isn't reliable enough to rate.

We don't have effectiveness data on file for the amino acid blend.

The evidence, ingredient by ingredient Alpha-gpc Phosphatidylserine

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both phosphatidylserine and alpha-GPC are generally well tolerated in studies, though long-term safety isn't fully established. Common side effects from phosphatidylserine include flatulence, stomach upset, headache, insomnia (especially at higher doses like 600 mg), and nausea — these can occur at doses of 200–300 mg daily.

Alpha-GPC rarely causes dizziness, headache, insomnia, diarrhea, heartburn, nausea, and vomiting. Rarely, it's been linked to stroke, particularly with use lasting 2 months or longer compared to non-users.

There isn't enough safety data during pregnancy or breastfeeding for either phosphatidylserine or alpha-GPC — talk with your doctor or pharmacist about whether this product is right for you in those situations.

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?
  • 2 of the 2 matched ingredients can interact with medications — Phosphatidylserine, Alpha-gpc.
  • The most serious interaction on file is rated Moderate.
  • For scale: 219 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 you take this product, double-check if you're on anticholinergic drugs (drugs for overactive bladder, Parkinson's, or related conditions) or cholinergic drugs — phosphatidylserine may affect their effectiveness. Also check if you use a scopolamine patch (Transderm Scop) for motion sickness, as alpha-GPC might reduce its effects.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

High G is aimed at muscle and athletic support, but the evidence for phosphatidylserine and alpha-GPC in athletic performance isn't strong. If you take anticholinergic or cholinergic medications, or use a scopolamine motion-sickness patch, check with your doctor or pharmacist before starting — this product may interfere with how they work.

Pregnant or breastfeeding? The safety data isn't there yet; talk it over with your own provider first.

High G Hardcare Formulation Muscle Booster by High T: Common Questions

Does High G Hardcare Formulation Muscle Booster by High T interact with any medications?
Yes. Based on its ingredients, High G Hardcare Formulation Muscle Booster has a known interaction with 219 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
High G Hardcare Formulation Muscle Booster contains 3 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.
What causes the side effects I've read about — headache, upset stomach, insomnia?
Those come from phosphatidylserine. Flatulence, nausea, and stomach upset can happen at doses around 200–300 mg daily. Headache and insomnia occur too, and insomnia is more likely when you take a higher dose like 600 mg. Most people tolerate it fine, but these are worth knowing if they happen to you.
Is this safe if I'm pregnant or breastfeeding?
There isn't enough safety information for either phosphatidylserine or alpha-GPC during pregnancy or lactation. The safety data advises against use unless your doctor directs otherwise. Talk with your doctor or pharmacist to decide what's right for your situation.
What's alpha-GPC and what's it supposed to do?
Alpha-GPC is a choline compound believed to support brain function and cognitive health. It's possibly effective for Alzheimer's disease, but the evidence for athletic performance or general cognitive boost isn't reliable enough to rate yet.
I've read that alpha-GPC can cause stroke — is that real?
In rare cases, alpha-GPC has been linked to stroke when used for 2 months or longer, compared to people who didn't use it or used it for less time. It's an uncommon side effect, but it's something to be aware of and to mention to your doctor if you're considering long-term use.
Does this product really boost athletic performance?
The evidence for phosphatidylserine and alpha-GPC in athletic performance isn't strong enough to rate reliably right now. That's what the data we hold shows — so talk with your doctor about whether it's the right choice for your fitness goals.
