Which Protein Is For You
SX-1XX · NEXT-GENERATION PROTEIN
Three proteins. One question.
How much do you want in the tub besides protein? That's genuinely the whole decision. Here's how they differ.
SX-101
ISO FORM
Three-ingredient whey isolate
PROTEIN PER SERVING
27 G
- Whey isolate, natural flavors, stevia. That's all.
- Highest protein per serving in the range
- Mixes thin — no gums, no oils
- 20 servings
SX-102
ISO ULTRA
Enhanced whey isolate + MCT
PROTEIN PER SERVING
22 G
- MCT oil powder, apple pectin, cocoa
- Richer texture, better mixability
- Micronutrients from the cocoa
- 24 servings
SX-103
ISO FAVA
Fava bean + fermented yeast
PROTEIN PER SERVING
21 G
- Plant-based. No dairy.
- Fava, not pea — smoother, less earthy
- Yeast protein fills the amino gaps
- 24 servings

STILL DECIDING
The short version.
Want the least in the tub? ISO FORM. Three ingredients and the highest protein per serving. It mixes thin — that's the trade.
Want it to taste like a shake? ISO ULTRA. The MCT and pectin are there for texture, and it's the one most people prefer drinking daily.
Avoiding dairy? ISO FAVA. Genuinely good plant protein rather than pea protein with flavouring stacked over it.
