PVL Gold Series ISO Gold 840g + FREE Flip n Sip Shaker

PVL Gold Series ISO Gold 840g — 27g Protein, Isolate + Hydrolysate, With Probiotic

ISO Gold is PVL's award-winning premium whey — 27g of protein per serve from a whey isolate and hydrolysate blend, with 6g of naturally occurring BCAAs and 1 billion CFU of shelf-stable DE111® probiotic in every scoop. No fillers, no amino spiking, no hidden proteins. 840g. In stock at TopDog Nutrition.

Isolate and Hydrolysate — Two Filtration Levels

ISO Gold isn't a single-source protein. It combines whey protein isolate with whey protein hydrolysate, and the difference between them is processing depth.

Whey protein isolate is filtered to roughly 90% protein by weight or above, stripping out most of the lactose and nearly all the fat. Higher protein per gram, and far less of the material that upsets sensitive stomachs.

Whey protein hydrolysate goes a step further. The protein is partially pre-digested using enzymes, breaking the long chains into shorter peptides. Your body has less work to do, so absorption is faster still. It's the fastest-absorbing whey form available, and the most expensive to produce.

Combining them gives you the purity of isolate with the absorption speed of hydrolysate — which is why ISO Gold sits at the premium end rather than competing with standard concentrate blends.

27g Protein, 6g Naturally Occurring BCAAs

27g per serve is at the top end for a whey product, and the 6g of BCAAs that comes with it is naturally occurring — intrinsic to the whey itself, not added as separate free-form aminos to inflate the panel.

That distinction matters, and PVL make a point of it: no amino spiking. Amino spiking is the practice of adding cheap free-form aminos like glycine or taurine so a nitrogen-based protein test reads higher than the actual complete protein content. It's legal, it's common, and it means the number on the label overstates what you're getting. PVL state plainly that ISO Gold contains no hidden or inferior proteins and no amino spiking.

Roughly a quarter of whey's amino acid content is leucine, isoleucine and valine — one of the highest natural BCAA profiles of any protein source. Leucine is the trigger that activates muscle protein synthesis, and a 27g whey serve clears that threshold comfortably.

1 Billion CFU DE111® Probiotic Per Scoop

This is the inclusion that sets ISO Gold apart from other premium isolates, and it's more useful than it sounds.

DE111® is a shelf-stable strain of Bacillus subtilis. Most probiotic strains are fragile — they need refrigeration and struggle to survive stomach acid. Bacillus subtilis forms spores, which means it survives manufacturing, sits stable in a tub at room temperature for the life of the product, and reaches the intestine intact.

Why put it in a protein: nutrient absorption happens in the gut. A protein you can't absorb properly is a protein you've partly wasted. Supporting gut microbiome health supports the digestion of everything you're eating, and it also helps with the bloating some people get from protein powder.

Zero Fillers, No Hidden Proteins

PVL manufacture in their own GMP-certified, federally registered facilities — over 200,000 square feet, licensed to produce for more than 100 countries. Because they export globally, their quality and safety standards have to meet the strictest regulatory regimes rather than the loosest.

ISO Gold is formulated without banned substances, with no hidden or inferior proteins padding out the protein claim.

Who It's For

• Anyone tracking macros closely. 27g of protein with minimal carbohydrate and fat means almost nothing comes along for the ride.
• Cutting phases. Maximum protein, minimum calories, so the calories you have left go to food.
• People whose stomachs don't like whey. Most whey intolerance is a lactose reaction — isolate removes most of it, and the DE111® probiotic supports digestion further.
• Post-training specifically. The hydrolysate fraction is the fastest-absorbing whey form there is.

Directions

Mix one scoop with 200–300ml of cold water or milk. Shake or blend until smooth.

Best within 30–60 minutes of training, or any time you need to close a protein gap. Water keeps the macros leanest and suits the light, fast-absorbing profile.

Allergens

Contains milk. Check the label for flavour-specific allergen information.

840g or 5lb?

The 840g tub is the right size for trying a flavour or for a few shakes a week. The 5lb tub drops the cost per serve considerably and is the sensible buy once you know which flavour you want and you're using it daily.

Frequently Asked Questions

What is amino spiking, and why does it matter?

Adding cheap free-form amino acids so a nitrogen-based protein test reads higher than the real complete-protein content. It's legal and widespread. PVL state ISO Gold contains none — the 27g is genuine protein.

Why is there a probiotic in a protein powder?

Because absorption happens in the gut. DE111® is a spore-forming Bacillus subtilis strain that survives manufacturing and stomach acid without refrigeration, supporting digestion of the protein you're taking and often reducing protein-related bloating.

Isolate or a standard whey blend?

Isolate is purer, leaner and lower in lactose, at a higher price. A concentrate-led blend like 100% Whey Gold is better value per gram of protein and creamier to drink. Cutting or lactose-sensitive: ISO Gold. Everyday protein: Whey Gold.

Is it lactose free?

Not entirely, but very low. Ultra-filtration removes most of it. Mild intolerance is usually fine; a diagnosed dairy allergy is not.
