Protein that earns its place in the shaker. Two proteins, two different jobs. Post Iso is 100% whey isolate: 24 g of protein in 110 calories per scoop, with DigeZyme digestive enzymes. It is the one that moves your daily protein total. Collagen Peptides is 10 g of grass-fed, hydrolyzed Type I and III bovine collagen per serving, built for connective-tissue support. Connective tissue is the part most lifters ignore until it starts complaining. It is not a whey replacement. Real doses, no filler.
WHICH ONE DO YOU NEED?
| If you want | Pick | Per serving |
|---|---|---|
| More protein in your day | Post Iso | 24 g protein, 110 calories |
| Connective-tissue support | Collagen Peptides | 10 g hydrolyzed collagen |
| To try a flavor first | Samples: Post ISO | One single-serve packet |
How much you need comes down to your bodyweight and your goal: run your numbers in the protein calculator, and the reasoning is in the complete protein guide. Post Iso is an isolate, filtered further than a blend, so a scoop carries more protein with less fat and lactose. It still contains milk. The side-by-side is in Whey Isolate vs Protein Blends.
