Product overview

This is a yeast-derived protein isolate rather than a whey or plant protein. Bigmuscles positions it as fermentation-derived, gut-friendly, and with a perfect PDCAAS score of 1, meaning it is a complete protein on paper. Each serving is claimed to deliver 33g of protein and 7g of BCAAs, which is competitive with mainstream whey isolates gram for gram. Being unflavoured, it is designed to mix into shakes, oats, or recipes without added sweeteners or flavouring — a plus for buyers avoiding sucralose or stevia.

Reasons to consider

• Verified ₹1,399 price on the Amazon product page — lower than the ₹1,599 level this product was listed at in recent weeks.
• Yeast protein suits buyers who are lactose-intolerant or want a non-dairy complete protein without soy.
• Unflavoured profile keeps the ingredient list short and flexible.
• Fulfilled by Amazon means standard delivery and returns handling apply.
• The advertised ₹41 coupon, if it appears on your account, trims the effective price further.

Pros and cons

Pros

• ₹1,399 for 1kg of isolate works out to about ₹139.90 per 100g — reasonable for an isolate.
• Complete protein claim (PDCAAS 1) with high per-serving protein content.
• Non-dairy, gut-friendly positioning for sensitive stomachs.

Cons

• Only 13 ratings so far — a thin review base for a supplement.
• Yeast protein taste and mixability are less proven than whey; unflavoured isolates can taste earthy.
• The ₹41 coupon is account/listing dependent and may not appear for every buyer.
• MRP is not shown on the page, so a percentage-off figure cannot be confirmed.

Buyer fit

Best suited to buyers looking for a dairy-free complete protein, or those curious about yeast protein at a lower entry price than premium isolates. If you already use whey comfortably and want a large flavour range, this unflavoured tub offers less. Check whether the coupon checkbox appears under the price on your account before checkout.

Final verdict

A verified ₹1,399 listing on a product that previously sold around ₹1,599 makes this a worthwhile buy if you are already in the market for a yeast or non-dairy protein isolate. The ₹41 coupon is a modest extra, not the main attraction. Worth it for lactose-avoidant buyers; others may prefer a flavoured whey at a similar price.
