Scope: Legal sports nutrition · seed /go/ slugs only.
TL;DR
- Yeh — whey isolate if lactose wrecks you. Not a detox.
- Concentrate is fine (and usually cheaper per 25 g protein) if dairy sits well.
- Hard dairy no → plant lane; check amino profile and AUD / 25 g.
- Buy on panel maths, not “gut cleanse” marketing.

Lactose vs “this powder hates me”
| Clue | More like lactose / dairy tolerance | More like something else |
|---|---|---|
| Bloat/urgency after concentrate shakes | Common pattern | — |
| Fine with hard cheese / yoghurt but not whey | Possible; still individual | — |
| Only happens when creatine is in the shake | Test creatine alone in water — Does creatine cause bloating? | Don’t blame mono by default |
| Rash, severe symptoms | Stop; see a professional | Not a DIY blog diagnose |
Not medical advice. Suspected allergy or clinical intolerance → qualified care, not another tub experiment.
Decision tree (keep it short)
- Tolerate dairy? → Start value WPC (usually best AUD / 25 g) — Cheapest protein
- Concentrate wrecks you? → Try isolate (typically less lactose) via a clear WPI on the panel.
- Still no / avoid dairy? → Plant blend; don’t pretend it’s automatically cheaper.
- Either way: run AUD / 25 g after shipping.

| Default / value whey | True Protein flagship path | /go/protein-true |
| Budget AU | Bulk when referral allows | /go/protein-bulk |
| Retailer browse (WPI/WPC SKUs) | Supplement Mart | /go/protein-sm |

| Plant / alt catalogue | Myprotein browse (no dedicated plant seed slug yet) | /go/protein-mypro |
Isolate-specific variant slugs (protein-true-wpi etc.) are optional map rows — not used here until Ops seeds them. Read the live PDP for WPI vs WPC.
Soft CTA: Lactose issue → pick a labelled isolate under /go/protein-true or browse /go/protein-sm. Dairy-free → /go/protein-mypro. Otherwise save coin on concentrate maths — /go/protein-bulk.
What isolate is not
- Not a gut detox
- Not automatically “more anabolic” if daily protein already matches
- Not a reason to ignore food quality
- Not a hormone/PCT product — hard skip on that branding
Stack context
Protein powder is conditional. Creatine is still the simple daily win for most beginners.
FAQ
Is isolate lactose-free?
Usually lower lactose than concentrate — not a medical guarantee. Read the label; your response matters.
Can I use lactase drops instead?
Some people do with food — still not personal medical advice. Isolate is the simpler powder swap for many.
Plant complete enough?
Blend for amino coverage; verify protein/scoop.
Women?
Same lactose/maths rules. No pink-tax requirement.
