The value is a defined role for each product and a lower bundled price than buying the same containers separately. You can review the exact formula behind each role, including the differences between the amino drink and joint capsules.

FOUNDER LED. PERSONALLY ACCOUNTABLE.
Built by someone who knows both sides.
Before building Hollow Labs, Allen Collins owned supplement stores. The questions customers asked then still shape the brand: what’s in it, how much do I take, and why is it worth buying?
We put the formulas where you can inspect them, explain where each product fits, and stay reachable when you need an answer.
What Hollow stands forHOLLOW LABSSEEK ADVERSITY.Ask the Hollow team
What exactly will I receive?
You receive one full-size retail container of every product shown in “What’s included.” Choose from the flavor options available above before adding the stack to your cart.
Will the whole stack last the same amount of time?
Not necessarily. Containers have different serving counts, and daily products can run out sooner than products used only for selected workouts. Each product card shows its supply at the stated serving.
Can I choose my flavors or swap products?
Choose the available flavor options in the selectors above. The products in each stack are fixed; open an individual product page if you prefer to build a different order.
Why include both an amino drink and joint capsules?
EAAX V2 and Elite Joint have different ingredient profiles and formats. The drink combines amino acids with joint ingredients; the capsules provide a separate joint-focused formula. Review both labels to decide how they fit your routine.
Will this replace sleep, food, or rest days?
No. The stack adds targeted supplements to those foundations. Adequate calories, protein, sleep, and sensible training remain the core of recovery.
Is there caffeine in this stack?
No added caffeine is listed in these four formulas. They still contain active ingredients and allergens, so review each product label before use.
How do shipping and returns work?
Free shipping applies to orders of $75+ after discounts, with eligibility confirmed at checkout. See our return policy for the 30-day return process and terms.
