What Goes Into the Glass

Each active, what it is there for, and what it gets you.

THE EDGE TAKEN OFF

L-theanine is the amino acid found in green tea, and on its own it has been studied for a settled, relaxed quality of attention rather than for energy. Its job in this tub is to smooth the caffeine, so what you get is the alertness without the restlessness that usually rides along with it.

A TWENTY-MINUTE ON-RAMP

Natural caffeine from green tea is the fastest thing in the formula and the one with the most evidence behind it for alertness and concentration. Mix it, drink it, and by the time you have opened the file you meant to open it has already started.

BLOOD FLOW FOR THINKING WORK

L-arginine is one of the building blocks your body uses to make nitric oxide, the signal that tells blood vessels to widen. Thinking work runs on supply the same way everything else does, so the hour you spend on the hard problem has circulation behind it and not only stimulation.

FEWER FLAT AFTERNOONS

Seven B vitamins sit underneath the actives, and the B group is the one most associated with tiredness and fatigue when someone is running short. They will not feel like caffeine. They are the reason a Thursday afternoon in week four is different from a Thursday afternoon in week one.

TWO SCOOPS, SIXTEEN OUNCES

One serving is two scoops in sixteen ounces of water, with a ceiling of five scoops in twenty-four hours. A 150 g tub works out at around eighteen servings, so a tub is roughly three working weeks if you use it on the days that need it rather than every day.

NO SUGAR TO COME DOWN FROM

The drop people blame on caffeine is usually the sugar underneath it in a can. There is none here, which is why the end of a session reads as a taper rather than a fall, and why you are not making a second decision about caffeine at four o'clock.

What to Expect

Week 1

Caffeine and L-theanine arrive together from the first glass, and this is the week you find out what that pairing feels like against plain coffee. Most people describe the same thing: the alertness turns up and the restlessness does not come with it.

Alpha-GPC is the one that rewards repetition. Choline is a daily input rather than a switch, and this is the stretch where the back end of a session starts holding as well as the front, which is where most focus drinks quietly run out.

Weeks 2 to 4

Weeks 4 to 8

Asian ginseng and the B group are the slow half, and this is where they compound. Ginseng has always been taken across seasons rather than sessions, and the difference it is aimed at is not nine in the morning. It is four in the afternoon.

By now the glass is part of how a deep block starts, the way a warm-up is part of a session. You stopped negotiating with your afternoons somewhere around week six. This is just how you work now.

Frequently Asked Questions

Here, and only here. CORTEX Focus Powder is sold through our own store rather than through marketplaces or retail shelves, which is how we keep the batch, the storage and the returns route under one roof.

Fourteen actives, in the order the label lists them: L-arginine HCl, inositol, Alpha-GPC, natural caffeine from green tea, L-theanine, Asian ginseng extract, black pepper extract, thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12 and pantothenic acid.

The rest of the tub is what makes it a drink: citric acid for the sour edge, natural flavour, polydextrose for body, sucralose as the sweetener, silicon dioxide to stop it caking, and vegetable juice powder for the colour. No sugar.

The label does not print a milligram amount against any of the fourteen. We have asked the supplier for the panel and will publish the amounts here the moment we have them.

Ask your doctor or pharmacist first, and mention these specifically:

  • Anything caffeine interacts with, which is a long list and includes some antibiotics, some asthma medication, and stimulants of any kind. The caffeine amount is not printed on this label, so it cannot be counted precisely against your daily total
  • Blood thinners and blood pressure medication, because Asian ginseng and L-arginine both have a documented interaction picture there
  • Diabetes medication, which Asian ginseng may interact with
  • Anything where absorption matters, since black pepper extract is included specifically to affect absorption

This product is not intended for anyone managing a medical condition without medical advice first.

Cool and dry, lid tight, out of reach of children. Do not use it if the safety seal is broken or missing on arrival.

Two things worth knowing about powders. The contents are sold by weight rather than volume, so the tub will look less full than you expect after shipping, and that is settling rather than short measure. And once you open it, use it within 90 days.

Two scoops into sixteen ounces of water, mixed, and taken before the work rather than during it. Give it about twenty minutes.

Do not exceed five scoops in any twenty-four hour period. If you are new to it, one scoop in the same sixteen ounces is a sensible way to meet the flavour and the caffeine at the same time, and you can move up from there.

Sixteen ounces is a lot of water for eight grams of powder, and that ratio is deliberate. Less water makes the sour edge sharp enough that people stop drinking it.

About eighteen. The tub holds 150 g and a serving is two scoops, which is 8 g, so 150 divided by 8 gives you 18 with a little left over.

That is arithmetic rather than a figure printed on the label, and we would rather show you the sum than round it up. If you use it on working days that need it rather than every day, a tub is around three or four weeks.

Not intended for children. Not for use by anyone pregnant or nursing, and not intended for anyone with a medical condition without speaking to a physician first.

This is a caffeinated product with the caffeine amount not printed, so if you are sensitive to stimulants, already at your ceiling from coffee, or taking it late enough in the day to affect your sleep, treat it accordingly.

It is made in a facility that also processes milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans and sesame.
