Those are quality brands — nobody’s arguing that. The question is whether taking 10–15 of their individual products gives you better outcomes than a single formula that was clinically tested as a whole. Your current stack was assembled from individual studies. IM8 was tested in a 12-week trial as a finished formula. Also, check your monthly spend — most people running a premium multi-brand stack are spending $300-$500/month. IM8 Essentials Pro is $78/month. The math alone justifies a 90-day trial.

AG1 is a greens powder with good branding. IM8 is a full-spectrum nutritional system covering 9 organ systems with 90 ingredients at published therapeutic doses. The difference is dosing and breadth. AG1 can’t physically fit therapeutic levels of CoQ10, MSM, magnesium bisglycinate, saffron, or a 10 billion CFU probiotic complex into their format and still taste like anything you’d drink. Check the labels side by side — the gap in dose transparency and ingredient density is significant.

Yes. NSF Certified for Sport — third-party tested for purity, potency, and banned substances per batch. This is the same certification required by the NFL, MLB, NHL, and PGA Tour. It’s not a label claim — it’s an ongoing, independent audit program. If you’re competing in any tested sport (or just want the assurance that what’s on the label is actually in the product at the stated dose), NSF Certified for Sport is the standard.

The Beckham Stack adds a dedicated longevity tier to Essentials Pro: NMN (300mg), Spermidine, Resveratrol, Fisetin, and Dihydroberberine (up to 5x more bioavailable than standard berberine). These target hallmarks of aging at therapeutic doses. If you’re already tracking biological age, investing in longevity protocols, or spending on standalone NMN — the Beckham Stack consolidates that into the same daily drink at $6/day. Research in this area is evolving, but the ingredient quality and dosing transparency are verifiable. Think of Essentials Pro as the core fund and the Beckham Stack as the longevity overlay.

Yes. IM8 is HSA/FSA eligible. That means pre-tax dollars, which — depending on your bracket — effectively reduces the cost by 30–40%. At $78/month for Essentials Pro, that’s roughly $47-$55/month after the tax benefit. You’re already good at this math.

Up to 90-day money-back guarantee. Full refund, no questions. This is a risk-free 90-day trial. If your Oura scores don’t improve, your energy doesn’t change, and your sleep is the same — you exit the position and walk away whole. The guarantee exists because the clinical trial data gives IM8 confidence that most people will feel a measurable difference within that window. If you don’t, they’ll give your money back. That’s a better risk/reward than most positions you’ve taken this quarter.
