Frequently asked questions
Is Everstack open for orders?
Not yet. We are in pre-launch. Join the waitlist and we will email you before checkout opens. No payment is taken today.
What brands are in the regimens?
Third-party certified products from established supplement brands. Brand partners are confirmed before launch and named on each product's lot COA. Later, our own-label versions of the four Foundation products will follow, made in cGMP facilities and tested the same way.
Why is the price the same as buying each product?
We price at the brands' retail value and add free shipping, curation, your daily guide, COAs and support. As our own-label formulas arrive, we expect to lower prices, and we will tell subscribers before any change.
How do subscriptions and cancellation work?
When checkout opens, regimens bill monthly and renew until you cancel. You will see the price, the renewal date and the cancellation steps before you pay. Cancel online in your account in two clicks, with no call required.
Do supplements replace medical care?
No. Supplements support a healthy routine; they do not diagnose, treat, cure or prevent any disease [1]. If you are pregnant or nursing, take medication or have a medical condition, talk to your clinician before starting.
Is creatine safe? Is it only for bodybuilders?
Creatine monohydrate is among the most studied supplements, with a long safety record in healthy adults at 3 to 5 g per day [2][3]. It is useful for anyone who does resistance training, at any age. Not for people under 18.
Why do you sell NR and not NMN?
NR has a lower regulatory risk profile. NMN is lawful as a supplement again since September 2025, but it remains a New Dietary Ingredient, so we would only offer it from suppliers covered by an acknowledged FDA notification, after counsel review [4].
Who are NOVA, Coach Max, Mateo and Big Lou?
They are AI-generated characters who host our explainer videos. They are always labeled as AI. They never share personal results, never give testimonials and are never presented as doctors.
Do you ship outside the US?
No. Everstack ships to US addresses only.
¿Tienen atención en español?
