Jeff Nippard built a YouTube audience by treating hypertrophy like a methods paper: controlled variables, citations, and a low tolerance for “secret” ingredients. When he published the supplements used during a 14-month natural bulk (covered in trade reporting such as BarBend), the list was short: creatine, protein powder, caffeine, fish oil, magnesium, vitamin D, a multivitamin, and ashwagandha.
That is the point of his protocol. He does not run 20 capsules because a podcast guest stacked them. He keeps compounds with replicated human data, then lets training volume and food do the rest.
X-Optimum has no affiliation with Nippard. This article uses publicly reported items from that training block and his broader evidence-based messaging so you can map the biology onto catalog SKUs, not so you can claim you are on “his stack.”
1. Creatine Monohydrate: Phosphocreatine, Not a Pump Trick
Creatine is the compound Nippard will not drop. In muscle, creatine phosphate donates a phosphate group to ADP so ATP can recycle during repeated high-intensity contractions. In neurons, the same buffer supports short bursts of cognitive work. Meta-analyses on creatine monohydrate keep landing on the same operational dose for most adults: about 3-5 g daily, no cycling required.
Loading (20 g/day split for 5-7 days) saturates muscle creatine faster. It is optional. What is not optional is consistency. Missed weeks drop intramuscular stores; the “it stopped working” complaint is usually compliance.
Optimized Creatine Monohydrate ($21.99) is the monohydrate salt, not a fancy ester. If you want the Nippard-style protocol, this is the non-negotiable SKU.
2. Protein Coverage: Collagen Is Connective Tissue, Not a Whey Clone
Nippard treats protein powder as a convenience layer on top of dietary protein, not as a hormone. Target ranges in the sports-nutrition literature sit around 1.6-2.2 g/kg/day for hypertrophy. Powder fills gaps when meals miss leucine.
X-Optimum does not sell whey. What it does sell is glycine-rich collagen for tendons, skin, and joint matrix. Collagen peptides will not replace whey for muscle protein synthesis. They still belong in a training stack if connective tissue is the limiter.
Grass-Fed Bovine Collagen Peptides Powder (Chocolate) ($24.99) supplies glycine, proline, and hydroxyproline. Use it beside whole-food protein, not instead of it.
3. Caffeine: Adenosine Antagonism With a Ceiling
Caffeine is Nippard’s pre-workout stimulant because the mechanism is boring and reliable. It antagonizes adenosine receptors, which is why perceived effort drops and why you should not slam it at 8 p.m. if you care about sleep architecture.
Keep the dose in the 3-6 mg/kg range used in performance studies, or lower if you are a slow metabolizer. Stacking five “focus” capsules on top of coffee is how people wreck sleep and then blame training.
Hemp Protein Fusion Coffee (Medium Roast) ($23.99) and Vitality Mushroom Fusion Coffee, Lion's Mane + Chaga ($24.99) are the catalog’s caffeine vehicles. Use one serving as the stimulant, not as a license to add more adenosine blockers at night.
4. Vitamin D and a Daily Multi: Hardware, Not a Personality
Vitamin D3 is a sterol hormone precursor. Low 25-hydroxyvitamin D shows up in strength, immune signaling, and mood data. Nippard’s public list includes vitamin D plus a multivitamin because he treats micronutrient gaps as training leaks, not as a branding opportunity.
Get a blood test if you can. Blind megadosing is not evidence-based. A multi that covers D, B-vitamins, and chelated minerals is the floor.
Optimized Multivitamin ($17.99) or, for a male-oriented formula, Optimum Male Multivitamin for Men ($17.99). Women can use Enhanced Women Multivitamin ($17.99) or Optimum Woman Multivitamin ($17.99).
X-Optimum does not currently sell a standalone fish-oil SKU. Omega-3s on Nippard’s list (EPA/DHA for membrane phospholipids and inflammatory tone) should come from fatty fish or a third-party tested oil. Do not fake that match.
5. Magnesium: NMDA Tone and Sleep Pressure
Magnesium sits on Nippard’s recovery side of the list. It is a cofactor in ATP reactions and modulates NMDA receptor activity. Deficiency is common in high-output training. Glycinate and threonate forms are usually better tolerated than oxide.
The catalog’s sleep formulas are the magnesium-adjacent tools, not a claim that they are identical to his personal brand of magnesium.
Optimized Sleep Formula ($17.99) and Better Sleep Strips ($17.99) are for sleep latency and overnight recovery. If you take caffeine like Nippard does, this is the other half of the adenosine story.
6. Ashwagandha: HPA Axis, Not “Calm Vibes”
Ashwagandha (Withania somnifera) is the only adaptogen that routinely appears on Nippard’s public supplement lists. Standardized root extracts (often KSM-66 or Sensoril in the literature) have human data on perceived stress and, in some trials, modest effects on strength and cortisol.
This is HPA-axis pharmacology. It is not a replacement for sleep, and it is not anabolic on its own.
Optimized Ashwagandha ($14.99) is the single-herb option. Ashwagandha and Shilajit Adaptogen Complex ($17.99) adds shilajit fulvic fractions if you want the broader adaptogen lane. Do not stack both on day one.
7. What He Does Not Center: Stimulant Blizzards and Mystery Blends
Nippard’s public posture is anti-junk: skip unproven fat burners, skip mega-stim pre-workouts, skip anything whose label is a paragraph of proprietary dust. That maps to X-Optimum’s anti-stimulant stance. If you want nitric oxide for training pumps, that is a separate, optional pathway (citrulline → arginine → NO → cGMP), not a required Nippard clone.
Optimized Nitric Oxide ($17.99) is available if vasodilation is a training preference. It is not on his published 14-month list.
Greens powders are also optional coverage, not a Nippard headline.
Superfood Greens Formula ($19.99) fills travel-day micronutrient gaps. Keep it secondary to creatine and protein.
Build Your Evidence-Based Hypertrophy Stack at X-Optimum
If you strip Nippard’s public protocol to biology, you get a phosphate buffer (creatine), amino-acid coverage (food plus protein or collagen), adenosine antagonism timed to training (caffeine), sterol and micronutrient hardware (vitamin D + multi), a divalent cation for ATP and sleep (magnesium), and one adaptogen with human data (ashwagandha). Omega-3s remain a food or dedicated oil.
Start with Optimized Creatine Monohydrate, a multi, and ashwagandha. Add sleep support if caffeine is late. Skip the 19-ingredient “bro stack.”
