Builds with use
In a 16-week trial, daily use raised cognitive scores week over week.
Brain support

Mori et al., Phytotherapy Research, 2009 (16-week double-blind, placebo-controlled). Lion's Mane is a dietary ingredient, not a medication, and is not intended to diagnose, treat, cure, or prevent any disease. Individual results vary.

Tested more than your morning coffee.
The internet made people nervous about sucralose. The science says the opposite. It's one of the most studied ingredients in the entire food supply.
What the regulators say
Two of the strictest food-safety bodies in the world reviewed it independently and landed in the same place.
Sources: U.S. FDA, high-intensity sweeteners and EFSA re-evaluation of sucralose (E 955). The Acceptable Daily Intake is a conservative lifetime limit, not a danger threshold.
Answers before you ask
Frequently Asked Questions
Is Ragnarok safe if I'm over 50 or sensitive to caffeine?
Yes — Ragnarok was specifically formulated with moderate-stim users in mind. At 225mg of caffeine (about two-and-a-half cups of coffee), it sits well below the 300–400mg you'll find in most aggressive pre-workouts. The caffeine is also paired with 100mg of L-Theanine, which smooths the curve and prevents the spike-and-crash older users typically dislike.
If you have a heart condition, high blood pressure, or are on medication, talk to your doctor first — we recommend that for any caffeinated supplement.
Will I crash after it wears off?
No. The crash most pre-workouts cause comes from a sharp 300mg+ caffeine spike with nothing to balance it. We pair our 225mg of dual-release caffeine with L-Theanine, which extends the smooth-energy window and softens the comedown. Customers consistently report feeling "dialed in, not wired" — and no slump 90 minutes later.
How long until I feel it?
Most users feel the focus and energy effects within 20–30 minutes. For best results, take Ragnarok with 12 oz of water about 25 minutes before your workout, gaming session, or anything else you need to lock in for.
Can I take it every day?
Yes. The dosing is conservative enough for daily use, and the L-Theanine plus crash-free profile means you won't build the dependency you might with a 300–400mg stim pre. That said, we recommend cycling off one day a week (typically a rest day) to keep your tolerance low and the effects strong.
What does Ragnarok taste like?
Strawberry Bifrost is sweet but not cloying — closest comparisons from customer feedback are Captain Crunchberries and Strawberry Nesquik (we're not affiliated with either). Sweetened with sucralose. Colored with beet root powder. Zero artificial dyes.
Why Lion's Mane and L-Theanine? What do they actually do?
Lion's Mane (250mg) is a nootropic mushroom backed by peer-reviewed research showing improved cognitive performance and reduced subjective stress, especially after consistent use over 28 days.
L-Theanine (100mg) promotes alpha brain waves — the "relaxed alertness" state. It's the reason green tea feels different from coffee despite both having caffeine.
Together, they shift Ragnarok from a "wired" pre-workout to a focused one.
What if I don't like it? How does the guarantee work?
Email us within 30 days of your order with your order number and we'll refund the full purchase price — even if the tub is half-empty. No return shipping required, no restocking fee, no "we'll send you a different flavor" upsell. We mean it.
How does the subscription work? Can I cancel anytime?
Subscribers save on every order and get free shipping. You can pause, skip, swap flavors, or cancel anytime from your account dashboard — no phone calls, no friction. There's no minimum commitment and no hidden renewal fee.
How fast does it ship?
U.S. orders ship from our warehouse within 3–4 business days and arrive in 5–7 business days. International shipping is available at checkout (typically 7–16 days). Tracking is included on every order.
