About this product

Whey Protein Isolate (Chocolate) is formulated with ultra-pure whey isolate to support muscle protein synthesis and efficient recovery in a smooth, rich chocolate flavor.

Suggested use

Mix 1 scoop (25 g) with 8–12 oz of cold water, milk, or your preferred beverage. Shake or blend until smooth.

Most athletes take whey isolate within 30–60 minutes after training, or anytime you need a clean protein serving to hit daily intake goals.

Store in a cool, dry place. Keep out of reach of children.

Contains: Milk. Not suitable for those with a milk allergy.

About monthlees

The supplement industry is built on inflated pricing, confusing labels, and aggressive marketing.

Monthlees exists to fix that.

We believe:

  • Supplements should be clinically dosed
  • Pricing should be transparent
  • Testing should be independent
  • And customers shouldn't pay for influencer commissions or retail margins

Instead of hiding costs inside the product price, we use a simple membership model — so you pay what supplements actually cost to make.

Shipping & returns

• Shipping: Orders are processed within 1–2 business days. Standard delivery takes 3–7 business days depending on your location.
• Returns: You may return or exchange products within 30 days of receiving your order. Items must be in original condition with proof of purchase.

Meta-analysis Whey protein

Whey protein supplementation and resistance training adaptations

Meta-analyses report that whey protein combined with resistance training supports greater gains in lean mass and strength compared with training alone — the core use case for isolate post-workout.
Review Whey isolate

Whey protein isolate vs concentrate — digestion and leucine

Nutrition reviews describe whey isolate as a rapidly digested, high-leucine protein source with lower lactose content than concentrate — supporting isolate positioning for lean recovery shakes.
Randomized trial Post-exercise whey

Timing of whey protein intake and muscle protein synthesis

Controlled studies show whey protein consumed after resistance exercise stimulates muscle protein synthesis more than other protein sources in acute feeding trials — supporting post-workout timing guidance.
Review Protein intake

Dietary protein requirements for active adults

Position stands summarize higher daily protein targets for athletes and active adults — contextualizing one-scoop isolate servings within total daily protein goals.

Why I created monthlees...

When I was 19 years old, I was diagnosed with a brain tumor. That experience forced me to start asking deeper questions about how the human body actually works.

Over the next 18 months, I immersed myself in studying health, nutrition, and neuroscience — eventually earning my degree in Neuroscience from Duke University. Along the way, I discovered something powerful: the body is incredibly resilient & inherently self-healing when it’s given the right support.

Strategic nutrition and supplementation became a major part of my own health journey. And over the last two decades, I’ve devoted my life to helping millions of people around the world take a more proactive role in their health.

That experience completely changed how I thought about health — and ultimately shaped the way Monthlees was built.

I created Monthlees because I was tired of seeing people pay premium prices for supplements that were under-dosed, over-marketed, and difficult to trust.

My goal is simple: build the kind of brand I would want for myself and my family — with better ingredients, transparent formulas, meaningful dosages, and a business model built on long-term trust.
