Product FAQs
How does Hasta Whey Protein Isolate taste?
Hasta Whey Protein Isolate is flavoured and is generally considered to have a pleasant taste.
What is Hasta WPI made from?
Hasta Whey Protein Isolate is a protein derived from milk.
How is Hasta WPI packaged?
Hasta Whey Protein Isolate is packaged in resealable 1kg pouches.
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.
Does Bulk do a 'normal' version of WPI?
Absolutely – our Whey Protein Isolate comes in a range of great flavours our customers tell us they love! Whereas our HASTA WPI range is regularly sent to HASTA to be tested, ensuring it’s safe for natural athletes, and currently comes in two flavours.
Does Bulk do a Natural version of WPI?
We do stock a range of Natural WPI flavours, however they don’t have a HASTA certification. That’s not to say there’s anything untoward in the product, it just means it’s not a product we’ve sent to HASTA to go through its comprehensive drug screen. If you’re a competitive athlete, the HASTA certification adds another layer of protection for you.

What Our Customers Are Saying
Reviewers consistently praised the pleasant taste, smooth texture and easy mixing, noting that the powder dissolved well in milk, water and almond milk with minimal clumping. Vanilla was a slight favourite, and several customers highlighted fast delivery and overall product quality. Customers subject to banned-substance testing valued the product’s HASTA-certified status. A small number mentioned awkward packaging, needing more liquid, limited Australian ingredients, or wanting longer use before judging performance.
