If you are looking at Per4m Advanced Whey Protein and the newer Per4m Advanced Protein Blend, the labels only tell you part of the story. The formulas are different, but for many people the deciding factors are much simpler: which one do you prefer to drink, which flavours suit you, and which would you actually want to use regularly?
That is now much easier to work out without buying two full tubs. Per4m has single-serving sachets for both ranges, so you can compare Advanced Whey and Advanced Protein Blend side by side before committing to a larger format.
This guide explains what each range is, how they differ, and a simple way to test them fairly. If you want the more detailed product-to-product breakdown, read our full Per4m Advanced Whey vs Advanced Protein Blend comparison.
Per4m Advanced Whey vs Advanced Protein Blend: the short version
Per4m Advanced Whey is the established whey range, using whey protein concentrate and whey protein isolate. Per4m Advanced Protein Blend takes a different approach by combining five protein sources: whey protein concentrate, milk protein, micellar casein, egg white protein and whey protein isolate.
Both are protein powders, but they are not simply the same product in different packaging. The different protein bases can affect the drinking experience, while the two ranges also have their own flavour choices. If you are unsure which sounds better on paper, samples give you a much more practical answer.
What is Per4m Advanced Whey Protein?
Per4m Advanced Whey is the brand's familiar whey-based protein range. It combines whey protein concentrate with whey protein isolate and is available in a large selection of dessert-inspired and more traditional flavours.
The full-size 900g product is listed as 30 servings, while the Per4m Advanced Whey Protein sample sachets provide a single serving and are currently available across a wide flavour selection.
For someone who already knows they like a conventional whey shake, Advanced Whey is the obvious reference point. It is also useful as the control in a comparison: make an Advanced Whey sachet and an Advanced Protein Blend sachet in the same way and you can judge the difference for yourself rather than trying to infer it from an ingredient list.
What is Per4m Advanced Protein Blend?
Per4m Advanced Protein Blend is a newer Per4m protein range built around a five-source protein blend rather than relying only on whey concentrate and isolate.
The five protein sources are:
- whey protein concentrate
- milk protein
- micellar casein
- egg white protein
- whey protein isolate
That makes the formulation meaningfully different from Advanced Whey. If you want a broader explanation of blended proteins and why brands use them, our guide to what a protein blend is goes into the category in more detail.
The Per4m Advanced Protein Blend sample sachets are 33g single servings, with the range including familiar Per4m-style flavours as well as options such as Cherry Cola Float. That makes the sachets particularly useful if you are curious about the new formula but do not yet know whether the range is for you.
What is actually different between Advanced Whey and Advanced Protein Blend?
1. The protein sources
This is the fundamental difference. Advanced Whey centres on whey concentrate and whey isolate. Advanced Protein Blend combines five sources, adding milk protein, micellar casein and egg white protein alongside whey concentrate and isolate.
That distinction matters more than the word “blend” on the front of the pack. You are comparing two genuinely different formulations rather than two sizes of the same protein.
2. The serving format
The Advanced Whey sample is a 30g sachet. The Advanced Protein Blend sample is a 33g sachet. The exact nutritional values vary by product and flavour, so check the product label for the sachet you choose rather than assuming every flavour is identical.
3. Taste and texture are personal
This is where a specification sheet becomes less useful. Two people can look at exactly the same ingredients and still prefer different shakes. Sweetness, thickness, flavour strength and the way a shake feels when mixed are personal preferences.
That is one reason we like samples at Muscle Supply. A full tub is a relatively big commitment when the thing you are least certain about is something only you can judge.
4. The flavour ranges are not identical
Advanced Whey has a broad established flavour range. Advanced Protein Blend has its own selection, including flavours that give you a reason to try the newer line in its own right.
If flavour is your main priority, do not feel that you have to decide on the formula first. You can start with flavours you genuinely want to drink, then see which range you prefer after trying them.
The easiest way to compare them: buy one sachet of each
If you have been searching for “Per4m Advanced Whey vs Advanced Protein Blend”, this is the part that makes the decision much easier.
Instead of buying a full tub of Advanced Whey and a full tub of Advanced Protein Blend, start with a sachet from each range. Ideally, choose flavours that are reasonably comparable or simply choose two flavours you would genuinely consider buying as a tub.

How to do a fair side-by-side protein test
You do not need to turn this into a laboratory experiment, but keeping a few things consistent makes the comparison much more useful.
- Use the same liquid. If you make one with water and the other with milk, you are partly comparing the liquid rather than the protein.
- Keep the liquid temperature similar. Cold water or milk can change how a shake tastes compared with room-temperature liquid.
- Use the recommended preparation as your starting point. Then adjust the liquid on a second try if you prefer a thinner or thicker shake.
- Use the same shaker or mixing method. A blender and a basic shaker can produce noticeably different results.
- Judge more than the first sip. Think about flavour strength, sweetness, consistency, aftertaste and whether you would still enjoy drinking it regularly.
You do not even have to drink both full servings at once. The point is to remove as many variables as possible so the difference you notice is more likely to come from the products themselves.
What should you actually compare?
When customers choose protein, the headline protein number is only one part of the decision. For a product you might use repeatedly, practical details matter too.
When you try the sachets, ask yourself:
- Which flavour would I be happier drinking several times a week?
- Do I prefer the consistency of Advanced Whey or Advanced Protein Blend?
- Is one too sweet, too mild or just right for me?
- Which mixes the way I like with my normal amount of water or milk?
- Would I still choose this flavour after the novelty wears off?
- Which full-size product makes more sense for my budget and how often I use protein?
Those questions are often more useful than trying to declare one formula universally “better”. The better purchase is the one that fits what you actually want from your protein.
What if you are mainly choosing by flavour?
Then samples are arguably even more useful. A flavour name such as Carrot Cake or Chocolate Brownie Batter can sound great, but that does not guarantee it will suit your taste.
Advanced Whey samples give you access to a wide selection without buying multiple tubs, while the Advanced Protein Blend sachets let you explore the newer range in the same way. If you want to go beyond these two products, our Per4m samples guide is a useful starting point.
You can also browse our wider protein sample range if you want to compare Per4m with other brands rather than only comparing the two Per4m formulas.
Can you compare different flavours?
Yes. Matching flavours can make a direct formula comparison easier, but it is not essential. If your real buying decision is between an Advanced Whey flavour you love the sound of and an Advanced Protein Blend flavour that interests you, test those.
The goal is not to produce a scientific verdict. It is to avoid spending full-tub money before you know what you enjoy.
Advanced Whey or Advanced Protein Blend: which should you buy?
If you already know you enjoy Per4m Advanced Whey and simply want another flavour, staying with Advanced Whey may be the straightforward choice. If the five-source formulation or the newer flavour selection interests you, Advanced Protein Blend is easy to explore through a sachet first.
If you are genuinely undecided, there is little reason to guess. Try one or two sachets from each range, prepare them in the way you normally make a shake, and decide from experience.
For the nutritional and formulation-focused comparison, see Per4m Advanced Whey Protein vs Advanced Protein Blend: Which Should You Choose?. That remains our detailed comparison of the two products; this guide is about the easiest way to test that choice for yourself.
Try before committing to a full tub
Protein samples remove one of the most annoying parts of buying a new protein powder: having to make a full-size purchase before you know whether you like it.
With both Per4m ranges now available in single servings, you can build your own comparison. Pick an Advanced Whey sachet, add an Advanced Protein Blend sachet, and see which one earns a place in your next full-size order.
