If you've ever finished a protein shake and spent the next hour feeling bloated, gassy and heavier than before you drank it, you already know the dirty secret of cheap whey: a lot of it doesn't actually get absorbed. It sits, it ferments, and you feel it.
That's the problem ASN — Advanced Sports Nutrition — set out to solve with HP-100 Hydrolysed Protein 100%. Instead of standard whey concentrate, HP-100 uses a hydrolysed NANO-peptide extract: protein that's already been broken down into small, fast-absorbing peptides before it ever hits your stomach.
The result is a powder that's 89% protein by weight, delivers 25g of protein per scoop with 0g sugar and 0g carbs, and — according to a wall of verified 5-star reviews — goes down without the bloat. Here are the 8 reasons lifters keep repurchasing it.
It's Hydrolysed — Pre-Digested for Fast Absorption
Most proteins make your gut do the work of breaking them down. HP-100 is hydrolysed whey peptides in a NANO form — the protein chains are already cleaved into small peptides, so they're designed to absorb quickly with minimal digestive load.
ASN positions this as the entire point of the product. In their words:
"The fastest absorbing protein in the world… its specific proteins are absorbed straight away with no side effects, including upset stomach or bloating."
Faster-absorbing protein is genuinely useful around training, when your muscles are most primed to use the amino acids you feed them.
The Macros Are Lean: 25g Protein, 0g Sugar, 0g Carbs
This is where HP-100 separates itself from the tub of "protein" that's secretly half filler. Straight from the nutrition panel, per 28g scoop:
That's ~89% protein by weight and just 107 calories a serve — lean enough for a cut, complete enough for muscle building, and clean enough to drink before bed. No sugar crash, no carb padding to inflate the protein-per-dollar maths.
The Reviews All Say the Same Thing: No Bloating
You can claim "easy on the stomach" all day — but it's the customers who decide. Because HP-100's peptides are separated from impurities (including most lactose) in the NANO process, ASN says it sidesteps the bacteria-driven fermentation that causes bloating and gas. The reviews back it up:
"My fav protein powder! It doesn't make me bloat or feel lethargic like other protein powders!"Kate · Verified HP-100 buyer
"Best protein. I've used this product for years. No bloating or stomach pains!"Dave S. · Verified HP-100 buyer
It's also very low in lactose and low in gluten, which ASN flags as ideal for people who usually struggle with dairy-heavy proteins.

ASN says the powder is so fine it has to be hand-packed into each tub. Reviewers notice — and they're using it for a lot more than shakes:
"The best tasting protein I've used. It's so fine you can mix it in with yoghurt and make protein sorbet too! So good."Bree F. · Verified HP-100 buyer
"Most amazing protein that truly matches a chocolate flavour… absolute bomber when mixing these as overnight oats."Phong Minh C. · Verified HP-100 buyer

Built for Recovery — and Reviewers Feel It
Fast-absorbing protein taken consistently is exactly what you want post-training, when the recovery window is open. ASN makes a bold promise about how quickly you'll notice — and while results always vary, owners are enthusiastic:
"By far the best protein supplement I have ever used! Part of my daily stack and post-workout meal. You have to try it to feel how good it helps with your recovery!"Steve L. · Verified HP-100 buyer
"Best results and performance I've experienced with any kind of protein product!"Darren R. · Verified HP-100 buyer
Individual results vary. Protein supports muscle building when combined with training and an adequate diet.
It Beats the Tub You're Currently Scooping
How a hydrolysed peptide protein stacks up against the usual suspects:
| Whey Concentrate | Whey Isolate | HP-100 | |
|---|---|---|---|
| Protein by weight | ~70–80% | ~85–90% | ~89% |
| Hydrolysed (pre-digested) | ✗ | Sometimes | ✓ NANO peptide |
| Sugar | Varies | Low | 0g |
| Carbs | 3–6g | 1–3g | 0g |
| Low lactose | ✗ | Lower | ✓ Very low |
| Bloat-friendly | Often not | Better | ✓ Reviewers agree |
At $99.95 for 32 serves, that's about $3.12 a serve for a hand-packed, hydrolysed peptide protein — premium, but priced like one for a reason.
Real 5-Star Reviews — From People Who Actually Train
Across ASN's verified Loox reviews, HP-100 buyers are overwhelmingly five-star, and ASN as a brand holds a 4.9★ rating across 177+ reviews. The recurring themes: taste, mixability, and — again — no bloating. The full review wall and customer photos are further down.
"Love this protein. It tastes amazing and blends well. It's become my favourite protein — I don't want to use another one after trying it."Gisele M. · Verified HP-100 buyer
It's Backed by ASN — and a Money-Back Guarantee
ASN — Advanced Sports Nutrition — is an Australian sports-nutrition company that stands behind HP-100 with a 100% money-back guarantee, calling it "unmatched for purity, potency, product performance & safety." The bold claims aside, that's a low-risk way to find out whether a hydrolysed peptide protein actually feels different in your own training.
ASN even makes a specific promise about the timeline:
"A protein which shows results within 14 days… when taken frequently, fast-absorbing proteins like HP-100 induce an anabolic growth effect."
