Independent Research

Grounded in Research From Two Continents

CREGEN's CGG Amino-Bridge™ approach has origins in KAIST research and is explored in an independent EIMEC pilot study — preliminary findings, honestly framed.

🇰🇷

South Korea

KAIST — Korea Advanced Institute of Science & Technology

Early research at KAIST is the origin of the CGG Amino-Bridge approach — pairing creatine monohydrate with glycine and glutamine to support better absorption and retention than standard monohydrate. The technology is backed by South Korean intellectual property and developed under Korean regulatory oversight, independent of any other manufacturing.

Independent Research Partner

EIMEC · Barcelona Pilot Study

EIMEC, an independent EU-registered research institution in Barcelona, conducted a small independent pilot study to explore bioavailability. In it, CREGEN showed significantly lower urinary creatine loss vs. a competitor — better retention. Higher serum and plasma trends were directional, not statistically significant. Preliminary and exploratory; larger studies are needed.

I'm a founder running a Series A startup. The difference in sustained focus after 3 weeks was undeniable. I stopped my 4-cup coffee habit. This is the real deal — not placebo.

I'm a physician. I read the research before ordering. The KAIST study is legitimate science. Impressive bioavailability data. I've recommended it to three colleagues already. My own focus and word recall have improved noticeably.

I've tried every nootropic on the market. Nothing comes close to CREGEN for sustained mental energy without the crash. The science backing is what separates it from everything else I've used.

Common Questions

Everything You Need to Know

When will I feel results?

Most users report improved energy and cognitive focus within 7–14 days of consistent daily use. Optimal results — including measurable improvements in mental clarity, sustained focus, and physical performance — develop over the full 30–90 day protocol as cerebral creatine stores reach saturation. We recommend the Protocol (3 boxes) for first-time users.

Do I need a medical license to buy?

No. CREGEN is a dietary supplement and does not require any professional license or medical credentials to purchase. It is available to all adults. CREGEN is GMP-certified, third-party tested, and contains no banned substances or controlled ingredients.

Can I cancel my subscription?

Yes, anytime — no fees, no hoops, no questions. Email us at info@cregenusa.com and we'll cancel within 24 hours. Subscriptions are billed monthly at the same price with free U.S. shipping every cycle.

How do I take it?

Mix one sachet (6g) with 250–350ml of water or your preferred beverage. Best taken in the morning or 30 minutes before exercise. No loading phase required. Consistent daily use — even on rest days — produces the best results. No blender needed.

Is it stimulant-free?

100% stimulant-free. No caffeine, no ephedrine, no synephrine. CREGEN works through cellular energy pathways — replenishing neuronal ATP reserves directly — not adrenal stimulation. This means no crash, no dependence, and no interference with your sleep.

What's your return & refund policy?

Every order is protected by our 30-Day Money-Back Guarantee. Try CREGEN for a full 30 days — if you're not completely satisfied with how you feel, email info@cregenusa.com and we'll refund your purchase. No need to return unused boxes, no restocking fees, and no lengthy forms. We only ask for a one-line note on your experience so we can keep improving the formula. Refunds are processed back to your original payment method within 5–7 business days.

How long does shipping take?

Orders are picked, packed, and shipped from our U.S. fulfillment center within 1 business day. Standard domestic delivery typically arrives in 3–5 business days, and shipping is always free on orders of $149 and up. You'll receive a tracking link by email the moment your order leaves the warehouse, so you'll know exactly when it's arriving. Subscriptions ship automatically on the same monthly cycle — always with free shipping — so you never run out mid-protocol.
