Why Creatine Form Doesn't Matter (But Purity Does)
The supplement industry has created dozens of "superior" creatine forms: creatine ethyl ester (CEE), buffered creatine, creatine HCl, liquid creatine, tri-creatine malate, and more.
The evidence is clear: In head-to-head trials, creatine monohydrate is as effective or better than all alternatives. The expensive "improved" forms offer no advantage.
What does matter:
- Purity: 99%+ elemental creatine (not fillers or contaminants)
- Micronisation: Particle size (finer = easier mixing, though effect on absorption is negligible)
- Cost per gram: Value matters when you're taking 5g daily indefinitely
All five products below are creatine monohydrate. The choice is based on purity, convenience, and value.
Bulk Creatine Monohydrate (Creapure)
Creapure certified, pharmaceutical-grade purity, and the cheapest per serving in the UK. The obvious long-term choice.
The Contenders: Five UK Creatine Products Tested
1. Bulk Creatine Monohydrate (Creapure)
What you get:
- Creatine monohydrate powder, 100% pure (Creapure certified)
- Unflavoured (white powder, mixes in water/juice/protein shakes)
- 100g, 250g, 500g, 1kg sizes available
- Creapure certification (pharmaceutical-grade, 99.9% pure)
- 20 servings per 100g (at 5g/day)
Cost per serving: ~£0.02-0.03 (best value available)
Cost per month (5g daily): ~£2.50-3.50
Quality assessment:
- Creapure certification (gold standard for purity)
- No fillers or additives
- Consistent crystal structure and purity
- Third-party tested (Creapure standard)
Strengths:
- Cheapest available (bulk powder)
- Creapure certified (highest quality assurance)
- No fillers or unnecessary ingredients
- Available in multiple sizes (starter to bulk)
Weaknesses:
- Powder form (requires mixing, less convenient than capsules)
- May have slight grit to it (some dislike the texture)
- Need a scale to measure 5g accurately (or estimate with spoon)
Best for: Cost-conscious lifters who don't mind powder mixing. The best long-term value by far.

How to use:
- Measure 5g (roughly 1 heaping teaspoon, though scale is more accurate)
- Mix in 200-300ml water or add to protein shake
- Timing doesn't matter; consistency (daily dosing) matters
- Slightly chalky taste (most people add to flavoured drinks)
2. MyProtein Creatine Monohydrate
What you get:
- Creatine monohydrate capsules, 1g per capsule
- 90 or 180 capsule bottles (90-180 days at 5g/day = 5 capsules)
- Unflavoured/neutral
- Standard purity (good, not Creapure-certified)
Cost per serving: ~£0.06-0.08 (5 capsules)
Cost per month (5g daily): ~£6-8
Quality assessment:
- Good purity (not explicitly Creapure, but MyProtein has good standards)
- Capsule form (contains microcrystalline cellulose filler, ~20% of capsule weight)
- Consistent, reliable brand
- No independent third-party testing published
Strengths:
- Convenient capsule form (just swallow 5 pills with water)
- Widely available (MyProtein website, Amazon UK, sports retailers)
- Affordable for capsule form

- Not Creapure certified
Realistic scenario: You're paying convenience (capsules vs powder). If you prefer capsules and don't mind paying 3x the cost, MyProtein is acceptable.
Best for: Those who want capsule convenience and are willing to pay for it. Good option if you travel frequently.

Over 5 years: Bulk saves £300+ compared to MyProtein capsules.
I switched to Bulk Creapure two years ago and have not looked back. At less than £3 a month, it is genuinely the best deal in sports supplementation.
My Recommendations: By Priority
Priority 1: Cost + Quality → Bulk Creapure Powder
Why: Best value anywhere (£2.50-3.50/month), Creapure certified (highest purity), zero fillers.
The trade-off: Powder requires mixing. Not a huge inconvenience. Most people mix into protein shakes or water.
Cost over 5 years: ~£150-210
Who should buy: Cost-conscious lifters, anyone taking creatine long-term (the savings compound).

Priority 2: Convenience + Quality → MyProtein Creatine Capsules
Why: Convenient capsule form (swallow 5 pills), decent purity, widely available, good brand.
The trade-off: Costs 3x more than Bulk Creapure per month.
Cost over 5 years: ~£360-480
Who should buy: Those who travel frequently, dislike powder mixing, or willing to pay for convenience.
Where to buy: https://www.awin1.com/cread.php?awinmid=2602&awinaffid=2838304&clickref=&p=https%3A%2F%2Fwww.myprotein.com%2F
Priority 3: Best of Both Worlds → Reflex Nutrition Creapure Powder
Why: Creapure certified (like Bulk), UK brand, available in capsule option if needed, competitive pricing.
The trade-off: Slightly less well-known than MyProtein; requires sourcing from Reflex or Amazon.
Cost over 5 years: ~£180-240
Who should buy: Those who want Creapure quality, prefer UK brands, or want the flexibility of capsule/powder options.

Protocol: How to Supplement Creatine
Loading Phase (Optional, Faster Results)
- Week 1-7: 5g creatine, 4 times daily (20g total per day), with meals containing carbs
- Weeks 8+: Drop to 5g daily (maintenance)
Alternative (Slower, Easier):
- Skip loading, start with 5g daily immediately
- Takes 4-6 weeks to reach muscle saturation instead of 7 days
- Same final result, just slower
Loading is faster but requires stomach capacity for 20g creatine daily. Most people prefer the slower no-load approach.
Maintenance Phase
- 5g daily, every day, indefinitely
- Take with food (carbs and protein improve absorption slightly)
- Timing doesn't matter: take morning, post-workout, or evening
- Consistency matters more than timing
Storage
- Keep in cool, dry place (room temperature is fine; refrigerator not necessary)
- Creatine monohydrate is stable at room temperature
- Seal container after use (avoid moisture)
Expected Results
Strength gains: 5-15% increase in 1-rep max, depending on training status (greater in untrained, more modest in advanced)
Lean mass gains: 1-2kg additional muscle over 8-12 weeks (from improved strength training capacity)
Onset:
- Loading: effects visible within 3-7 days
- No-load: effects emerge after 4-6 weeks
Persistence: Effects are maintained indefinitely with continued supplementation. Stopping creatine causes gradual return to baseline over 4-6 weeks (no withdrawal effects).
Safety and Side Effects
Water retention: Intracellular (inside muscle), not subcutaneous. You may gain 0.5-1kg water weight, which is fine.
Muscle cramps: Some athletes report cramps on creatine. Mitigation: adequate hydration (2-3L daily) and electrolytes (sodium, potassium, magnesium).
Kidney concerns: Thoroughly debunked. Decades of research show no kidney damage in healthy individuals. Elevated serum creatinine is expected (creatine is a byproduct of creatine metabolism); this is not kidney damage.
GI distress: Rare with monohydrate. Some people experience bloating on loading doses (20g/day). Solution: skip loading and use slower protocol.
Cost: Cost per gram is low enough that long-term supplementation is financially sustainable (~£2-8/month).
Flavoured vs Unflavoured: The Debate
Most creatine is unflavoured powder (white, chalky). Some brands sell "flavoured" creatine.
Why unflavoured is better:
- Cheaper
- Can mix into any drink (coffee, protein shake, juice)
- Flavoured versions add sugar or artificial sweeteners
My recommendation: Buy unflavoured, mix into your protein shake or juice. No downside.

Summary
Creatine form does not matter: purity does. Buy Creapure-certified monohydrate from Bulk or Reflex and take 5g daily. Everything else is marketing.
Best value: Bulk Creapure Powder (~£3/month, Creapure certified, zero fillers). The obvious choice if you're committing long-term.
Most convenient: MyProtein Capsules (~£7/month, easy swallowing, widely available). Worth the premium if you value convenience.
Best balance: Reflex Nutrition Creapure (~£4/month, Creapure certified, UK brand, powder or capsule options).
What to avoid: Expensive "improved" creatine forms (CEE, buffered, HCl, etc.). They offer no advantage and cost significantly more.
Creatine monohydrate, 5g daily, is one of the most proven, safe, and cost-effective supplements available. Choose Bulk if cost is primary, MyProtein if convenience matters, or Reflex if you want Creapure quality at mid-range pricing.
Take it daily, train hard, eat enough protein, and expect 5-15% strength gains over 8-12 weeks. It works.
