Frequently asked questions about Hasta WPI

How does Hasta Whey Protein Isolate taste?

What is Hasta WPI made from?

Hasta Whey Protein Isolate is a protein derived from milk.

Are samples of Hasta WPI available?

How is Hasta WPI packaged?

Is the packaging for Hasta WPI recyclable?

In theory yes, but not in all council areas right now.

The REDcycle program has been discontinued, and the industry is working together to find a solution to continue recycling soft plastics. For now, we recommend checking with your local council, but most require you to put the packaging in your regular landfill bin.

The included scoop can be recycled as hard plastic in your local council pickup.

Can I receive a discount buying more than one bag of Hasta WPI at once?

Absolutely! Price breaks for Hasta Whey Protein Isolate begin when you purchase 2 units of any flavour. Just add more than that to your cart to see the savings.
