WIP offers energy pouches in two strengths, 100 mg and 200 mg of caffeine per pouch. The purpose of this article is to compare both brands with as little bias as possible, to help you understand which product may be better suited for your individual and specific needs. For this showdown we have selected WIP's 100 mg pouches to compare against SZN.
WIP and SZN both put 100 mg of caffeine in a pouch, and WIP prints its doses on the label: niacin, vitamin B6, vitamin B12 and chromium, each at 50 to 75 % of the daily value. That honesty is worth saying out loud, because it is rarer than it should be in this category.
The differences sit elsewhere. WIP's L-theanine appears under "other ingredients" with no amount. Its B12 is cyanocobalamin rather than the active methyl form. And the pouch itself is a large, dry, 1-gram format that WIP's own guidance says to keep in "as long as the flavour lasts, typically 20+ minutes", while SZN's slim, moist pouch is designed to last up to 90 minutes, 4.5× longer-lasting flavour than WIP pouches.1
"Energy, stamina, alertness."
Natural caffeine from green coffee, 100 mg per pouch. Chemically identical to the caffeine in SZN, and identically dosed. This row is a tie, and the strongest thing on WIP's label.1
"Energy metabolism, cognitive function."
Disclosed and real: niacin 8 mg, B6 0.85 mg, B12 1.8 µg, chromium 17.5 µg, at 50 to 75 % of the daily value. The B12 is cyanocobalamin, the synthetic form the body must convert, where SZN uses methylcobalamin, the active form.1
Listed under "other ingredients".
The one active with no number. It sits after the sweetener and emulsifier on the label, with no dose. Studied at 200 mg, which is the entire active budget of a pouch, so in an otherwise honestly dosed product this line reads as a trace inclusion.7
"Keep it in as long as the flavour lasts, typically 20+ minutes."
A large, dry pouch that WIP suggests removing once the flavour fades. Buccal uptake needs contact time, so a 20-minute stay shifts delivery toward what you swallow. Think of the pouch as a tea bag: less time in the cup, weaker tea.1
Credit where due. WIP discloses its vitamin doses, offers a 200 mg strength for people who want it, and sells a wide flavour range. Those are real advantages. The question this article raises is what the format does with the ingredients, and how much of the label reaches you through the lip.
SZN through the same lens. Five ingredients, every one disclosed on the label and dosed at or above the level the claim requires. No proprietary blends, no trace inclusions.
Measured values first, then the things you only learn by using both. The second group is our judgement from using both products, flagged as such, not a lab value.

This is where the two products differ most. WIP uses a large, dry pouch of about 1 gram, which many users find uncomfortable and irritating on the gums. SZN uses a slim, moist 700 mg pouch designed to sit under the lip without irritation, and to keep releasing for around 90 minutes.

Adding active ingredients to a pouch is a very interesting prospect. The pouch acts as a carrier that lets an ingredient reach your bloodstream faster than travelling through the entire GI tract, by passing through the oral mucosa. This is known as buccal absorption.
For it to actually work, the active ingredient needs to meet certain criteria, and it needs time in contact with the mucosa. WIP's own guidance is to let the ingredients release into your saliva and swallow, keeping the pouch in for around 20 minutes. That works, but it turns the pouch into something closer to a slow drink. SZN's lock-in formula is pH-neutral and moisture-optimised to pass the oral mucosa directly, and to keep doing so for the length of a working session.
Passive diffusion through the mucosa favours molecules under roughly 500 daltons. Larger molecules largely stay in the pouch until swallowed.
Moderately fat-soluble molecules cross fastest. Strongly water-loving or charged molecules diffuse slowly even when small.
Uptake through the mucosa is a rate, not an event. A pouch removed after 20 minutes delivers a fraction of what the same pouch delivers over 90.
Both pouches clear the gate, because both are built on caffeine and small B-vitamins. What differs is contact time: a 20-minute stay shifts delivery toward the swallowed fraction, a 90-minute plateau keeps it at the mucosa. You could say the pouch is a tea bag. Less time in the cup, weaker tea.

SZN contains four B-vitamins, each above 100 % of the daily reference intake, with B12 as methylcobalamin, the form the body uses directly. WIP contains three B-vitamins at 50 to 75 % of the daily value, with B12 as cyanocobalamin, the synthetic form that must be converted first. WIP also adds chromium picolinate at 17.5 µg, which relates to blood-sugar maintenance rather than focus.
SZN is manufactured in Sweden, considered by many to be the birth nation of the pouch, and is third-party tested by one of the world's leading laboratories, Eurofins. This way you can be certain that each pouch contains what the label says. WIP manufactures in North America and sells as a US dietary supplement under the FDA disclaimer, without third-party testing.
Both brands generate a lot of strong customer feedback, for the product and for customer support. As everyone's tolerance to caffeine is unique, some users are bound to feel nothing no matter whether they pick SZN, WIP or any other caffeinated pouch. That is why SZN offers a full 30-day money-back guarantee, so anyone can order and try the pouches.
Showcasing only five-star reviews doesn't say much. The unhappy customers are the biggest source of learning, so we compare the share of one-star reviews.
WIP is a fair product with an honest label, a 200 mg option and lots of flavours. Where it falls short is the pouch itself: large, dry and, by its own guidance, out after 20 minutes. SZN puts the same caffeine and a stronger B-vitamin complex in a slim, moist pouch built to work at the mucosa for around 90 minutes, and proves every dose with a third-party certificate.
