RANGE Three products, and no plans for a fourth

A short range you can actually keep honest.

A catalogue of thirty means most of them are the same formula in different bottles. Three is what we can test every lot and still explain without hedging.

01 Formulation

Trial doses, or nothing.

Most of this category works by putting a famous ingredient on the label at a dose no study ever used. It is cheaper, it is legal, and it does nothing.

Where an ingredient has human trial data, we use the dose from those trials and we cite them. Where it does not, we leave it out — which is why the labels are short and why there are only three of them.

02 FIBER is the clearest example. Glucomannan at 3 g per day, split across three 1 g doses in water before meals: the exact protocol behind the only authorised weight-management claim in the European register. Not 500 mg folded into a blend, which is what most of the market sells.

02 What this will not do

It does not work on its own.

A supplement does not create a calorie deficit. It can make one easier to hold — a viscous fibre before a meal is genuinely filling, and sleeping properly changes what you reach for at 4 p.m. That is the size of the effect, and we are not going to describe it as anything larger.

Anyone selling you a number of pounds in a number of days is either guessing or lying. We would rather lose that sale.

03 Verification

The certificate is for your lot. Not a representative one.

A supplier's certificate of analysis describes the raw material they shipped us. It says nothing about what ended up in your bottle. So we test the finished product, every lot, and publish it.

IDENTITY + POTENCY Every lot, independently assayed HPLC identity and potency on the finished product, not on the raw material certificate the supplier sent us.
CONTAMINANTS Heavy metals, micro, residual solvents Tested to USP limits. A lot that fails does not ship, and the failure is published alongside the passes.
TRACEABILITY Certificate published per lot code The lot code is printed on the base of the bottle. Enter it and you get that specific certificate, not a representative one.
MANUFACTURE cGMP-registered facility, 21 CFR 111 Facility GMP certification issued by an accredited third-party registrar, renewed annually.
04 The back of the bottle

We put the regulated panel on the front.

The Supplement Facts panel is the one part of a supplement label that has to be true in a specific, enforceable way. Most brands hide it behind a tab called “details”.

It is also, once you stop treating it as an obligation, the most credible-looking object in the category. So it is the first thing on every product page, above the story rather than beneath it.

05 What buyers said
★★★★★

“The lot code thing sold me more than the marketing did. I checked the certificate before I opened the bottle.”

MARCUS T.  ✓ VERIFIED PURCHASE
★★★★☆

“Taking the fibre before lunch is the only part of this that changed my day. It is not magic, it is just easier to stop eating.”

PRIYA R.  ✓ VERIFIED PURCHASE
★★★★★

“Ordered 01, cancelled the subscription after two months to try it monthly instead. Took about four seconds, which is not what I expected.”

06 Questions
How do I cancel a subscription?

From your account page, in one click, at any time — the same way you started it, with no phone call and no retention gauntlet. You can also skip a shipment or change the interval. We email you three days before every renewal, with the amount and the date, and a cancel link in that email.

What can these actually do?

They are dietary supplements, not medicine, and they do not work in the absence of a change in what you eat. Where an ingredient has human trial data we have used the dose from those trials and we cite them. Where it does not, we say so. Anyone in this category promising a specific number of pounds in a specific number of days is either guessing or lying.

Why only three products?

Because a range of thirty means most of them are the same formula in different bottles. Three formulations is what we can test properly, every lot, and still explain honestly.

Where can I see the test results?

The lot code on the base of your bottle resolves to the certificate of analysis for that lot — identity, potency, heavy metals, microbiology. Not a representative sample from a different batch.

Do you ship outside the US?

Currently the US, Canada and the UK. EU shipping is pending per-country notification, which is required before a supplement can be placed on the market in most member states — we would rather wait than ship into a market we are not cleared for.

Is this suitable for everyone?

No. Not for anyone under 18, pregnant, nursing, or taking prescription medication without talking to a doctor first. New York state law additionally requires age verification and an adult signature on delivery, so orders shipping there will ask for both.

Start with one bottle.

No trial that converts into something. No cancellation phone number. One bottle, and an email three days before anything renews.
