What's in it?
Five supplements, each with a defined role: Creatine (5g), Energy+, Protein (Whey Isolate or Plant), Omega-3, and Magnesium (optional add-on). No fillers. No proprietary blends. Every ingredient is listed, dosed, and explained further below.
Who's it for?
People who train consistently and want a structured supplement system that matches their effort, gives them clarity and control, and the real confidence they're striving for. Not for beginners looking for a quick fix, but for those serious enough to do it right.
What you'll notice first
Most people feel it in their training first: better energy, sharper focus, and cleaner recovery between sessions. Physique improvements follow with consistent training and nutrition over weeks.
Backed by science
Every stack is built from ingredients with strong clinical evidence. We emphasize effective dosing, clear timing, and quality standards so results are more repeatable.

    Creatine

    A clinically studied performance staple used to increase muscle creatine stores, supporting power output, strength, and repeatable training volume.*

    What It Does
    Helps regenerate ATP (quick energy) so you can push harder efforts and recover faster between sets, compounding performance over time.*
    Why Ours
    Pharmaceutical-grade creatine monohydrate, 5g per serving, the dose used in the majority of clinical research. Manufactured in an NSF-certified facility.
    What To Expect
    Some notice better training performance within 1–2 weeks. The bigger payoff builds over weeks as muscle stores stay saturated.

    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

    Omega-3

    A concentrated source of EPA and DHA that supports post-exercise recovery, specifically the reduction of muscle soreness and markers of muscle damage during hard lifting blocks.*

    What It Does
    Supports recovery between sessions by targeting markers of muscle damage and soreness through EPA and DHA.*
    Why Ours
    High-potency fish oil concentrate from anchovies and sardines resulting in high EPA & DHA and low mercury content compared to other fish sources.
    What To Expect
    Effects build over time. Most people notice reduced muscle soreness in the days after hard sessions at 2 weeks and beyond with consistent use. Not an immediate effect, and not a strength or performance boost. This is a long-term recovery investment.

    Whey Isolate or Plant Protein

    A high-quality protein base designed to help you consistently hit daily protein targets , one of the main drivers of muscle growth and recovery when paired with lifting.*

    What It Does
    Helps you reach daily protein targets that support muscle protein synthesis and recovery.*
    Why Ours
    Whey Isolate: a pure, fast-digesting protein with high protein per scoop with only three ingredients.

    Plant: built on Tendra® fava bean protein isolate and YESTEIN™ fermented nutritional yeast protein for a more complete amino profile and smoother digestion with only 8 ingredients.

    Clean and natural formulas with stevia sweetener, not sucralose (the artificial industry standard).
    What To Expect
    You feel the benefit when it improves consistency and fills in protein gaps. Physique changes follow after weeks of aligned training and nutrition.

    "I assessed the Muscle Stack against one standard: does the evidence support what this formulation claims to do, at the doses provided. It does. The ingredients are present at clinically meaningful levels, the combination is physiologically sound, and nothing is included without justification. If you train seriously and want a supplement system you can trust, the science behind this one holds up."

    "I was skeptical at first. But the stack does really do as advertised. It's only been a few weeks and I already see an improvement in all areas and most importantly, I can tell my muscles are going to be noticeably bigger by the third month. Going to be staying on the stack for 6 months. Thanks Astrand." - Sebastian O.

    Your Optimal Schedule

    With meal twice daily

    Omega-3

    Take with a meal to reduce aftertaste. Consistent daily intake is what builds the recovery effect over time.
    Pre-Workout 30-45 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.
    Post-Workout Anytime

    Creatine

    Creatine works by saturating muscle stores over time; consistent daily intake is what builds the effect.
    Night 30-60 minutes before bed

    Magnesium

    Magnesium supports relaxation and sleep quality, which is when recovery and adaptation happen.

    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 creatine 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.
