How an IV Formula Actually Gets Designed (It's Not Vibes)

Someone decides what goes in the bag, at what dose, in what order — and at most companies you'll never learn who or why. Here's our formula design process, opened up: the physician, the constraints, the arguments.

The design process behind every formula bag

The Surge contains 500mg of NAD⁺. Not 250. Not 1000. Five hundred — and there was an argument about it. An actual argument, in a protocol review, between our medical director and the clinical literature and the session-length math and the honest question of what members would reliably rebook. The 500 won on the merits. That argument is the product. Most of this industry would rather you not think about whether their menu ever had one.

So here's the process opened up: how a formula actually gets designed at a legitimate operation — the people, the constraints, the trade-offs — so you can hold any drip menu in the county up to the light and see whether anyone argued over it.

Step one: the job description

Every formula starts as a use case, not an ingredient list. The Hangover IV's brief: counter four specific injuries (fluid loss, B-burn, gut revolt, inflammation) in under an hour on a nauseous client. The Surge's brief: the most complete single wellness session buildable within safety constraints. Design runs backward from the job — which is why formulas differ at all, and why the menus that read like the same six vitamins reshuffled fourteen times were built forward from a price list instead.

Step two: the physician and the literature

The medical director owns the protocol — a written document (its existence is itself the credential) defining each ingredient's dose, the infusion rate, the contraindications, and the screening questions it obligates. Doses come from clinical literature and established parenteral practice, not from marketing round numbers: magnesium at levels that help without flushing, vitamin C at grams because that's where the IV route's advantage lives, NAD⁺ at 500 for the reasons that won the argument. Every milligram has a citation or it doesn't ship.

A protocol is a formula's birth certificate. Ask to see one — the reaction tells you everything.

Step three: the constraint gauntlet (where amateur menus die)

Then chemistry gets a veto. Compatibility: some compounds degrade or precipitate when mixed — the reason certain trendy combinations don't exist isn't imagination, it's chemistry (and the reason glutathione often runs as its own push at the end). Osmolarity: the solution's total concentration must stay vein-friendly; you can't just keep adding — every addition dilutes room for others. Formula design is substantially the art of what you can't combine. Rate rules: NAD⁺ demands slowness, magnesium has ceilings — the bag's contents dictate the session's clock. Stability: mixed vitamins degrade on timelines measured in hours, which is why per-visit compounding is a quality marker and pre-mixed bags-in-a-fridge are a red flag. Screening load: every ingredient added is a contraindication list inherited — the protocol's screening questions grow with the formula.

Step four: the feedback loop

Ship, then listen. Nurse reports (who's flushing at what rates), member outcomes (does the recovery formula actually shorten the reported recovery), new literature — all of it feeds protocol review, where doses get defended again or revised. Our own Peak Performance exists because the Surge's process revealed a distinct athlete use-case that deserved its own brief. A menu that never changes isn't timeless; it's unattended.

The question that sorts the county

All of this compresses into one question you can ask any provider: "Who designed this formula, and can I see the doses?" The legitimate answer names a physician and produces milligrams. The other answer is a pause, a pivot, or a "proprietary blend" — which translates, roughly, to nobody argued over this bag. Ours were argued over. It's the best thing we can tell you about them.

FAQ

Good questions.

Who actually designs wellness IV formulas?

At legitimate operations: a physician medical director working with pharmacists and clinical literature — producing written protocols that define ingredients, doses, rates, contraindications and screening rules. At the other kind: whoever built the menu that weekend. 'Who designed this and where are the doses written down?' is the question that sorts them.

Why do doses matter more than ingredient lists?

Because 'contains glutathione' spans a 50mg token and a 1000mg working dose — same menu line, completely different product. Ingredient lists are marketing; milligrams are medicine. It's why we publish ours.

What limits what can go in one bag?

Real constraints: chemical compatibility (some compounds degrade or react when mixed), osmolarity (the solution's concentration has to stay vein-friendly), infusion-rate requirements (NAD⁺'s slow drip, magnesium's ceiling), stability windows (why compounding happens per-visit), and the screening implications each addition creates. Formula design is mostly the art of what you CAN'T combine.

How often do formulas change?

When evidence or feedback argues for it — doses get revisited against new literature, ingredients earn or lose their slots, and member outcomes feed back into the protocols. A menu that's never changed isn't stable; it's unattended.
