    Optimal Add-On

    Resilience

    Magnesium

    Lorem ipsum dolor sit amet, consectetur adipiscing elit,

    Why add it:
    National data suggests about 52% of Americans do not meet daily magnesium needs, so an add-on can help fill the gap.

    Conder adding if you:
    rarely eat magnesium-rich foods: nuts, seeds, legumes, leafy greens, whole grains.

    If you're unsure:
    Most people tolerate magnesium well and some excess is excreted, but too much can cause GI upset. Add it if your diet is low.

    Energy+

    A performance-focused pre-workout blend combining caffeine + L-theanine with taurine and electrolytes to support energy, focus, and training drive without feeling overly jittery.*

    What It Does
    Supports energy, focus, and perceived effort during training.*
    Why Ours
    Balanced stim profile (200 mg caffeine + 100 mg L-theanine) with taurine and electrolytes for session quality.
    What To Expect

    What It Does

    Your Optimal Schedule

    With meal twice daily

    Omega-3

    Dietary fat improves absorption and reduces “fishy” aftertaste; steady intake supports recovery/joint comfort over time.
    Pre-Workout 20-30 minutes before

    Energy+

    Caffeine supports training drive and output; L-theanine smooths the feel for steadier focus.
    Post-Workout Anytime

    Protein

    Muscle growth is driven by total daily protein; post-workout is simply an easy time to consistently get it in.
    Night 30-60 minutes before bed

    Magnesium

    Magnesium supports relaxation and sleep quality, which is when recovery and adaptation happen.
    Post-Workout Anytime

    Creatine

    Creatine works by saturating muscle stores over time; consistent daily intake is what builds the effect.

    Frequently Asked Questions

    1. How do I take the Muscle Stack?

    Each product includes timing guidance on the label. Creatine daily at any time. Energy+ 30-45 minutes before training. Protein around your workout or between meals. Omega-3 with a meal. Magnesium 30-60 minutes before sleep.

    2. Do these supplements work on their own?

    No. The Muscle Stack is designed to support training, not replace it. Real results require consistent training, adequate protein intake, quality sleep, and proper recovery. Supplements accelerate progress when the foundation is in place. They don't create progress from nothing. If you're not training consistently or eating enough protein, no stack will fix that.

    3. Why was the Muscle Stack built as a stack instead of individual supplements?

    Single supplements work in isolation. Stacks work in synergy. The Muscle Stack covers three pillars simultaneously: Performance (Energy+ and Creatine), Recovery (Omega-3 and Magnesium), and Foundation (Protein). When all three are covered consistently, the results compound in a way individual supplements can't replicate.

    4. How is Astrand's dosing different?

    Most brands dose each supplement to work on its own. Astrand dosed every supplement in the Muscle Stack in context of the other four, matching clinical evidence while accounting for ingredient interactions, timing, and redundancy. Every dose was a decision, not a default.

    5. Do I need to do a creatine loading phase?

    No. 5g of Creapure® daily saturates muscle creatine stores within 3-4 weeks without a loading phase. Loading isn't necessary and causes digestive discomfort for many people.

    6. How should I choose between Whey Isolate and Plant Protein?

    Whey Isolate is a fast-absorbing dairy protein with a lean macro profile. Plant is a complete pea and fava protein, dairy-free and easier on digestion. Both hit the same daily intake targets. Pick based on dietary preference or tolerance.

    7. What if I'm sensitive to caffeine?

    Energy+ contains 200mg of natural caffeine per serving, about the same as two cups of coffee. If you're caffeine sensitive, start with a half serving or skip pre-workout days. Do not take Energy+ within 6-8 hours of sleep.

    8. How was the Muscle Stack developed?

    Every ingredient was evaluated using the LUMEN framework: Literature, Utility, Mechanism, Effective dose, and Notes for use. Months of ingredient review, advisory board evaluation, and beta testing preceded every formulation decision. If the evidence didn't support the dose or the ingredient, it didn't make the label.

    9. How does the refill schedule work?

    Subscriptions refill based on each supplement's actual serving size, not a fixed 30-day cycle. Creatine lasts 50 days. Energy+ lasts 25. Protein lasts 28. Each product ships when you're running out. Pause, skip, or cancel anytime from your account.

    10. Can women take the Muscle Stack?

    Yes. Every ingredient and dose in the Muscle Stack is supported by research in both men and women. Creatine, protein, omega-3, and magnesium all show benefits across sex. The stack is not hormonal and does not cause unwanted muscle bulk.
