What you can expect
Caffeine supports alertness, while the formula brings several focus ingredients into the same drink. Built for sessions where being mentally engaged matters.
Tyrosine, Alpha GPC, enXtra®, and Noogandha™ lead the positioning.
This is a caffeinated product, not a stimulant-free focus drink.
The key amounts here are for one full scoop. The label also gives a half-scoop option.

Why choose this formula?
Choose Focus for a caffeinated, focus-first formula. Shadow puts stimulant intensity first; Berserker Stim adds substantial carbohydrates and pump ingredients.
| Consideration | Your priority | What you get |
|---|---|---|
| Focus | Mental engagement is the priority | Tyrosine + Alpha GPC + botanicals |
| Shadow | Stimulant intensity is the priority | A more stimulant-heavy ingredient profile |
| Berserker Stim | Broader training formula | Carbs + pump + focus + high caffeine |
This stuff works. No headache or anxiety like a lot of other pre, just a quick/noticeable energy hit. Mushroom flavor is a little odd but it comes with the territory (I don’t drink this for the taste.) Highly recommend.
It actually does what it says, it gives a nice boost of energy and focus without the over top surge other pre-workouts tend to do. It does not negatively impact sleep or recovery and it tastes good.
10/10 for workouts and for study/deep work.
1/2 to 3/4 scoop works great - most won't need a full scoop, so it lasts longer than the # of servings suggests.
Flavor is on point, too. Can't recommend enough.
What surprised me was how productive I was after the gym. The mental benefits don’t wear off quickly.
Your routine
For experienced users, mix 1 scoop in 10–12 oz of water before training. The label directs new users to start with ½ scoop in 8–10 oz, about 15 minutes before a workout. Do not combine with other caffeine or stimulant products.
The Hollow standard
Before building Hollow Labs, Allen Collins owned supplement stores. The questions he heard from customers still shape the brand: what is in it, how much do I take, and why should I choose it?
Our standard is simple: make the formula easy to understand, explain where it fits, and stay reachable when you have questions.
Meet Hollow Labs ↗Yes. One scoop is 13g and the tub contains 20 full servings. The smaller column on the label is half a scoop, not one scoop.
Per full scoop, the label lists 200mg caffeine anhydrous and 100mg Infinergy di-caffeine malate. The malate ingredient includes non-caffeine mass, so these are shown separately.
Check for duplicate caffeine, huperzine A, and other actives first. Avoid combining stimulant products and seek professional guidance for complex stacks.
Adults only. Avoid during pregnancy or nursing and if stimulant-sensitive. Consult a healthcare professional if you take medication or have a medical condition. Avoid close to bedtime.
