Not all whey protein is created equal.

After months of investigating 52 different whey protein brands, Dr. Christian Gonzalez uncovered a truth the industry doesn’t want you to know: only 5 passed his strict standards for purity, transparency, and safety.

Most companies either ignored requests for testing data, refused third-party transparency, or hid behind marketing claims.

In this episode, Dr. G breaks down how to separate clean, effective proteins from the toxic imposters and why the difference matters for your longevity, muscle health, brain, and hormones.

🔍 What You’ll Learn

• The 5 cleanest whey proteins of 2025

• Hidden toxins and contaminants most brands don’t disclose

• Why low-quality whey can damage your brain and nervous system

• What true transparency looks like — and which companies failed to provide it

⸻

🧾 The Criteria

Every brand was asked to provide:

• Source of protein (grass-fed, organic, non-GMO)

• GMP or third-party-audited manufacturing

• Certificates of Analysis for every batch

• Testing for heavy metals, pesticides, glyphosate, microbes, and allergens

• Cold micro-filtration processing (no solvents or high heat)

• Clean formulas free from fillers and artificial sweeteners

Only five companies passed every test.

⸻

🚫 Brands to Avoid

Dozens of companies failed to respond, denied participation, or refused transparency — including some of the most trusted names in fitness.

Without third-party testing, you simply can’t know what’s in your protein powder.

💬 Final Thoughts

In 2025, there’s no excuse for secrecy in the supplement industry.

If a company can’t prove what’s in their product, they don’t deserve your trust or your money.

If you care about your longevity, muscle health, and protecting your brain and hormones, this is a must-watch.
