Macro
25g — without the filler.
Most cheap proteins pad the scoop with maltodextrin and fillers. This is the actual 25 grams the label promises, in the form your muscle actually uses.

A quieter system
Three ways the shift shows up.
Source
Grass-fed dairy, cold-filtered.
Cold-cross-flow is the gentler way to filter whey — leaves the protein intact, not heat-cooked. Closer to the milk it came from, further from the chemistry lab.
Taste
Vanilla. Like the actual bean.
Stevia, monk fruit, real vanilla. No sucralose chemical sting, no neon-yellow dye, no artificial coffee-creamer aftertaste at the bottom of the shaker.

Whey Protein Isolate (Cold-Cross-Flow Filtered)
Form: 25 g whey protein isolate (per 30 g scoop) · grass-fed dairy source
A high-bioavailability protein source studied extensively for muscle-protein-synthesis support. Isolate form (vs concentrate) is lower in lactose and higher in protein-per-gram. Cold-cross-flow filtration preserves native protein structure.

Whey Protein Isolate
“ON gold standard has been the best. I tried so many different powders, cheaper ones, 'good' ones according to reviews, those with fantastic macros, nothing tops it. Best taste, best mixability, really good macros (not a lot of junk - a lot of tasty ones have high carbs/fat), and consistent protein content % through independent lab tests. There's also a version with natural instead of artificial flavoring if you are trying to avoid excess consumption of it.”Read the original
“IME ON Gold Standard never sat well with my stomach. A product that’s worked for me is [brand removed] ProteinSeries. It’s an exceedingly expensive product when considering competitors, but I’ve found it works best for me (flavour, mixability, digestion). If I were to have whey more frequently (currently I have 3-4 scoops per week) I’d consider some cheaper options as this can get very expensive very quickly.”Read the original
“Tissue synthesis doesn't occur only on the days you exercise. Arguably, exercise is doing the opposite; it's causing tissue breakdown. It's when you are sleeping/recovering that tissue synthesis is taking place, and those processes are obviously taking place even when you're not at the gym. Daily protein intake is important, even on days when you're not exercising”Read the original

Honest answers
Questions you actually asked
Is it lactose-free?
Whey isolate has dramatically less lactose than concentrate (typically under 1 g per scoop), but it's not strictly lactose-free. Most people who tolerate dairy at all tolerate whey isolate. Strict lactose-intolerance: skip this and look at a plant-based option.
Why cold-cross-flow filtration?
It's gentler than alternative methods. Ion-exchange filtration uses chemicals that can denature the protein; cold-cross-flow uses temperature and pressure only — preserves more of the native protein structure.
How does it taste?
Genuine vanilla bean — closer to a French-vanilla custard than a candy-store vanilla. Less aggressively sweet than sucralose-loaded proteins.
How does it mix?
Cleanly with a shaker — 10 seconds, no clumps. Smoother in a blender if mixing with frozen fruit or oats.
When should I take it?
Post-workout (within 60 minutes) is the classic timing for muscle-protein-synthesis applications. Otherwise, any time of day — daily protein totals matter more than precise timing.
Is grass-fed real or marketing?
Our source farm certifies grass-fed dairy — the cattle's diet is primarily pasture-based. The nutritional difference at the protein level is modest, but the source-quality and animal-welfare standards are meaningfully better.
Can I take it with my ashwagandha?
Yes — they don't conflict. Common stack for active adults: whey post-workout + ashwagandha daily + creatine.
Is it safe to take daily?
Yes for most healthy adults. Protein needs scale with body composition and training volume. If you have kidney conditions or are unsure of your protein needs, talk to a registered dietitian.
What if it doesn't work for me?
Email contact@withanly.com within 30 days of delivery and we'll refund the full amount — you don't need to send the tub back.
How fast does it ship?
From our US warehouse, USPS Ground typically arrives in 2–4 business days within the contiguous US.
