When you’re scrolling through endless tubs of protein powders, hydration mixes, and amino acids, it’s easy to wonder: which brands are actually worth it? Per4m is one that’s been steadily building a reputation in the UK supplement scene. But is it really good? Is it safe? And—maybe most importantly—does it deliver on value?
This in-depth review looks at Per4m’s quality, safety, product range, and effectiveness, with a close focus on the six key products in their lineup. If you’ve ever asked “is Per4m a good brand?” or “what supplements from Per4m should I use?”—this guide has your answers.
Is Per4m Protein Batch-Tested? (Informed Sport & Quality Control)
One of the first things serious lifters, athletes, and health-conscious customers ask is whether their supplements are batch-tested for banned substances. That’s especially crucial for proteins, pre-workouts, and recovery products, because contamination has been an industry-wide issue for years.
Per4m has leaned heavily into transparency and testing. Their protein powders—including the flagship Per4m Advanced Whey Protein (2.01kg) and the premium Per4m Whey Hydrate (1.8kg)—are Informed Sport certified. This means every batch is independently tested for banned substances, giving athletes confidence that they can use it without risking a failed drug test.
Batch testing isn’t cheap for companies, which is why some budget brands skip it. But Per4m’s choice to certify their proteins puts them closer to the likes of Applied Nutrition and Optimum Nutrition in terms of quality standards.
Verdict: For athletes and serious gym-goers, batch testing alone makes Per4m protein a smart pick over cheaper, uncertified alternatives.
Is Per4m Protein Good Quality—And Where is Per4m Based?
Per4m is a UK-based company, which gives them a leg up in terms of quality control compared to bulk importers who white-label overseas powders. Being UK-made means tighter manufacturing standards, clearer labelling, and fresher product distribution.
But what about taste, mixability, and actual performance?
-
Per4m Advanced Whey Protein (2.01kg) – The workhorse of the range. It’s a whey concentrate and isolate blend, which balances cost and quality. Smooth texture, great flavour range, and an easy shake for both bulking and cutting. At just under £48 for over 2kg, it’s good value for a premium-tested whey.
-
Per4m Whey Hydrate (1.8kg) – The more advanced option. Think of it as Per4m’s “refined” whey: higher protein percentage, faster absorption, and electrolyte fortification. It’s aimed at athletes chasing recovery speed and lean muscle support. At £79.99, it’s a big step up in price, but it delivers a higher-grade formula.
-
Per4m Plant Protein (2kg) – For vegetarians and vegans, this is a surprisingly strong entry. Many plant proteins taste chalky or thin, but Per4m has dialled in a creamy texture and plenty of flavour options (chocolate, vanilla, salted caramel). With 2kg at £37.99, it’s competitive against bulk vegan proteins—without sacrificing taste.
Verdict: Per4m nails protein quality across whey and plant bases, and the Informed Sport batch testing makes it one of the safer UK-made choices.

Per4m Hydrate Electrolyte Mix – Your Everyday Edge
Hydration is the foundation of performance, but most gym-goers massively underestimate it. Even a 2% drop in hydration can cut strength and endurance noticeably.
What is Per4m Hydrate Electrolyte Mix?
A powdered drink mix that replenishes electrolytes lost through sweat. Each serving delivers:
-
Sodium, potassium, calcium, magnesium, chloride, phosphorus
-
Light, refreshing flavour (Citrus Burst) without being overly sweet
-
Only 10 calories per serving
Why it’s useful:
-
Supports muscle contractions during tough workouts.
-
Prevents cramping and fatigue in long cardio or high-heat sessions.
-
Great for athletes on low-carb diets (since glycogen depletion flushes electrolytes).
Pricing & value: At £15.99 for 210g, you get 30 servings—so about 50p a drink. Compared to bottled electrolyte drinks, it’s a bargain and far more environmentally friendly.
Who it’s for:
-
Endurance athletes (runners, cyclists, HIIT lovers).
-
Heavy lifters sweating buckets during long gym sessions.
-
Anyone cutting weight who feels sluggish from electrolyte imbalances.
Verdict: Per4m Hydrate is one of those “daily use” products that goes beyond bodybuilding—it’s a lifestyle supplement for better energy and wellbeing.
Is Per4m a Fat Burner or Just a Protein Powder?
One common question is whether Per4m is just about protein, or whether they make fat burners and performance enhancers.
The truth: Per4m isn’t a stimulant-heavy “fat burner” brand. They don’t push aggressive thermogenics or hardcore fat-loss pills. Instead, they focus on the core nutrition and recovery stack: protein, hydration, amino acids, and sleep support.
For fat loss, Per4m helps indirectly by:
-
Offering low-sugar, high-protein shakes that support satiety.
-
Providing Hydrate Electrolyte Mix (210g), which helps reduce water retention and combat fatigue during calorie deficits.
-
Supporting quality sleep with Per4m Sleep (120 Caps), since poor sleep is directly linked to fat gain and slower recovery.
If you want caffeine-loaded burners, look at brands like Applied Nutrition (ABE) or EHP Labs (OxyShred). If you want a more sustainable, health-focused approach, Per4m fills the gap.
Is Per4m Whey Safe to Take Every Day? Any Side Effects?
This is a big one—people worry about whether daily whey protein shakes are actually safe. The answer: for most healthy adults, whey protein is one of the safest supplements you can take daily.
Per4m’s whey range uses a blend of concentrate and isolate, which is standard in high-quality powders. Possible issues:
-
Digestive discomfort – Some people struggle with lactose in whey concentrate. If that’s you, the Whey Hydrate formula (isolate-heavy) is gentler on digestion.
-
Kidney myths – Whey protein doesn’t “damage kidneys” unless you already have severe kidney disease.
-
Over-reliance – Whey should supplement your diet, not replace whole foods.
For plant-based diets, the Plant Protein 2kg is not just safe but beneficial, since it plugs the gaps in amino acid intake that vegetarians often face.
Verdict: Daily use of Per4m protein is safe, provided you balance it with real food. The only real “side effect” is getting stronger and fuller.
Which Per4m Protein is Best for Bulking (Muscle Gain)?
For bulking, the focus is on calorie-dense, protein-rich, and recovery-optimised shakes.
-
Per4m Advanced Whey Protein (2.01kg) – Best for lean bulking. Plenty of protein with moderate calories.
-
Per4m Whey Hydrate (1.8kg) – Best for athletes bulking cleanly. Lean protein with electrolytes, helps support higher training volumes.
-
Per4m Plant Protein (2kg) – Great for vegetarians aiming for growth, though typically paired with carbs to boost calories.
For a complete bulking stack, pair Advanced Whey with Per4m Glutamine (400g) for recovery and muscle repair.
Which Per4m Shake is Best for Weight Loss?
If your goal is cutting weight, you’ll want:
-
Low calories per scoop
-
High satiety
-
Electrolyte support to prevent fatigue
The standout here is:
-
Per4m Whey Hydrate (1.8kg) – Ultra-lean, with electrolytes to keep energy levels up while in a deficit.
-
Per4m Hydrate Electrolyte Mix (210g) – Keeps hydration in check, especially when cutting carbs (which naturally flush water out).
-
Per4m Sleep (120 Caps) – Underrated for weight loss. Better sleep = lower cortisol = easier fat loss.
Verdict: Per4m approaches weight loss holistically—protein for satiety, electrolytes for energy, and sleep support for hormone balance.
The Healthiest Type of Protein Powder (Whey vs Plant)
Per4m caters to both ends:
-
Whey – Higher leucine content, faster muscle protein synthesis, ideal for recovery.
-
Plant – Lower allergen risk, dairy-free, gut-friendly, sustainable.
Neither is “unhealthy”—it depends on your diet and tolerance. The fact Per4m offers both shows they aren’t pushing one agenda, but rather covering multiple lifestyles.
How Much Protein Should I Eat Per Day If I Use Protein Powder?
General guidelines:
-
1.6–2.2g of protein per kg of bodyweight is ideal for muscle growth and maintenance.
-
A 75kg male should aim for 120–160g of protein daily.
-
Protein powder should fill the gaps, not be the bulk of your intake.
One scoop of Per4m Advanced Whey gives ~21–23g protein. That means two shakes per day gets you ~45g protein—around one-third of daily needs for most lifters.
Why Do Some Doctors Say No to Whey—And Who Should Avoid Protein Powder?
The scepticism often comes from:
-
People with lactose intolerance – who may feel bloating.
-
People with kidney disease – who need controlled protein intake.
-
Those replacing entire meals with shakes – which can lead to nutrient gaps.
For the majority, however, Per4m protein is not just safe but beneficial for performance, weight management, and recovery.

FAQs + verdict
Is Per4m Good? A Full Review (Part 2)
In Part 1, we broke down Per4m’s protein line-up and explained how it stacks up for muscle gain, weight loss, and everyday use. But the brand is more than just whey. Per4m also makes a small but smart set of performance and recovery supplements—and this is where the brand really cements its place as one of the UK’s most reliable names in sports nutrition.
Let’s take a closer look at three often-overlooked supplements that deserve more spotlight: Per4m Glutamine, Per4m Sleep, and Per4m Hydrate Electrolyte Mix.

Per4m Glutamine – Recovery’s Unsung Hero
Glutamine isn’t as flashy as creatine or pre-workout, but it’s one of those supplements that can quietly make a real difference—especially if you train hard or diet aggressively.
What is glutamine?
Glutamine is the most abundant amino acid in the body, crucial for muscle repair, immune health, and gut function. During intense training or illness, levels get depleted. That’s why athletes often supplement with it.
Why Per4m Glutamine?
-
Ultra-Pure Micronised Formula – Per4m keeps it simple: 100% glutamine, finely milled for better mixing.
-
400g tub for £16.99 – That’s 80 servings of 5g, making it one of the best value aminos on the UK market.
-
Versatile use – Add to your post-workout shake, intra-workout drink, or even bedtime shake.
Benefits you’ll notice:
-
Faster recovery between sessions.
-
Reduced soreness on higher training volumes.
-
Better gut support during cutting diets (especially when fibre intake is low).
Verdict: Per4m Glutamine won’t change your physique overnight, but if you’re serious about recovery, it’s one of the best low-cost “edge” supplements you can add.
What’s the #1 Best Protein Powder Overall?
This is the million-pound question. The best protein powder isn’t just about protein percentage—it’s about taste, digestibility, price, and trust.
For Per4m:
-
Everyday Value: Per4m Advanced Whey Protein – affordable, great taste, versatile.
-
Performance & Recovery: Per4m Whey Hydrate – higher cost but optimised for results.
-
Plant-Based: Per4m Plant Protein – creamy, flavourful, and more enjoyable than most vegan blends.
In a crowded market, Per4m consistently scores high for flavour variety and quality control.

Per4m Sleep – Advanced Relax Formula
This is where Per4m gets creative. Most supplement brands focus only on training fuel, but recovery—especially sleep—is where progress is actually made. Enter Per4m Sleep (120 caps).
Why sleep matters for athletes:
-
Growth hormone and testosterone peak during deep sleep.
-
Poor sleep increases cortisol, which slows recovery and promotes fat gain.
-
Without quality rest, training intensity nosedives.
What makes Per4m Sleep different?
It’s not just a melatonin capsule. Instead, Per4m uses a synergistic formula with:
-
Magnesium (600mg) – Helps muscle relaxation and combats cramping.
-
L-Theanine (300mg) – Calming amino acid often found in green tea.
-
Zinc + other co-factors – Support hormone regulation and immune health.
Dosing: 4 capsules before bed. A single tub lasts a full month.
What you’ll notice:
-
Falling asleep quicker, with fewer restless nights.
-
Deeper sleep cycles = better recovery and fresher mornings.
-
Knock-on effects: improved gym performance, sharper focus, even easier weight management.
Value check: At £28.99 for 120 caps, it’s cheaper than many standalone magnesium or sleep aid stacks—yet combines everything into one formula.
Verdict: If you struggle with recovery, Per4m Sleep is easily one of the most underrated products in their range.
Putting It All Together – The Per4m Stack
By now, you can see that Per4m isn’t a one-trick pony. Their lineup covers protein, hydration, amino recovery, and sleep support—the four pillars of performance.
Here’s how an ideal daily Per4m stack looks:
-
Morning: Per4m Advanced Whey or Plant Protein shake.
-
Intra-workout: Per4m Hydrate Electrolyte Mix.
-
Post-workout: Per4m Glutamine + Per4m Advanced Whey.
-
Evening: Per4m Sleep before bed for deep recovery.
With this, you’re covering muscle growth, hydration, gut health, immune function, and rest—everything you need to maximise results.
