Highly Anticipated 420g Size Launched for 'VALX Hybrid Protein,' Which Sold Out Immediately After Release and Ranked #1 on Amazon and Rakuten!

VALX Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; CEO: Masayuki Tadai; hereinafter 'VALX'), operator of the fitness brand 'VALX (Bulk's)', announces the launch of a new 420g size of its 'VALX HYBRID PROTEIN,' a new product that has achieved the #1 ranking (※) on both Amazon and Rakuten Market, making it more accessible for trial use.

Immediate sell-outs after launch: A new choice combining whey and soy gains strong response

'VALX Hybrid Protein' is a new type of protein powder born as a fresh alternative that leverages the unique benefits of both whey and soy protein.

Commonly held beliefs such as 'whey protein is best for muscle training' or 'soy protein is better for dieting' are widely accepted. However, in reality, neither is absolutely superior—what matters most is choosing based on your personal goals and lifestyle.

VALX developed this product as a new option that allows users to enjoy the benefits of both whey and soy without being bound by conventional thinking.

This product is designed with the intention of transcending the divide between 'whey fans' and 'soy fans,' offering greater freedom in protein selection.

Following its release, the chocolate flavor sold out temporarily on Amazon, and initial stock for both flavors sold out on Rakuten Market—receiving stronger-than-expected response.

In response to customer feedback such as 'I'd like to try the whey-soy hybrid protein once' and 'I want to taste it first,' VALX is launching the more accessible 420g size.

Features the 'Milky-Rich Process' (patent pending), developed to maximize deliciousness

'VALX Hybrid Protein' uses VALX's proprietary 'Milky-Rich Process' (patent pending).

Generally, protein powders containing soy protein often receive feedback about chalkiness or distinctive aftertaste.

VALX has rigorously focused on taste, achieving a smooth mouthfeel and rich, milky flavor even when combining whey and soy. The process suppresses the typical protein aftertaste, creating a delicious product you'll want to drink every day.

Take this opportunity to enjoy a new protein experience that combines the best of both whey and soy.

※Ranked #1 on Amazon's Multi-Protein Best-Seller Ranking (as of June 8, 2026) and Rakuten Market's Daily Ranking (updated June 4, 2026) in four categories: Diet & Health, Supplements, Protein, and Multi-Protein.
