Most protein powders hide behind vague labels and plastic tubs. We don’t.

Open Source Labs is the only brand that tests for microplastics, verifies label accuracy, screens for heavy metals, and uses plastic-free packaging. Every batch is checked, verified, and transparent — so you know exactly what you’re putting into your body.

Clean. Smooth. Neutral.

Because we don’t use artificial flavors, gums, fillers, or sweeteners, the taste is pure and natural — perfect in smoothies, oatmeal, or shakes without that chalky or chemical aftertaste.

Yes.

We run independent microplastic screening on every production run. Most brands don’t test at all — or package their powders in plastic tubs, which can shed micro-particles. With Open Source Labs, you get verified microplastic-safe protein in plastic-free packaging.

We use organic, grass-fed, U.S.-sourced whey (or your alternative protein type), chosen for purity and hormone-free quality. No blends. No hidden ingredients. Just a clean, traceable raw material you can trust.

Very.

Our formula is intentionally simple — no gums, no fillers, no artificial sweeteners, no mystery “natural flavors.” That means less bloating, easier digestion, and better absorption for most people.

Each order contains 30 servings, designed to last a full month for most daily users.

Yes — truly.

Unlike nearly every protein brand that uses plastic tubs and scoops, we use fully plastic-free, recyclable packaging to protect both your health and the planet.

Protein isn’t a stimulant — the difference is in how your body feels over days and weeks, not minutes.

Most customers report:

• Less bloating by week 1
  
• Better recovery by week 2
  
• Visible muscle + performance improvements by weeks 3–4
  
  Clean inputs create clean outcomes — and your body feels the difference.
