I was spending over $300/month on supplements from various brands. With Monthlees, I get the same quality — actually better, since everything is tested† — for less than half. My stack costs me $120 now.

I've tried every subscription box and DTC brand out there. Monthlees is different — it's like Costco for supplements. I'm saving 50%+ on my monthly† essentials without compromising on quality.

The transparency is what sold me. I can see exactly what's in each product, where it's sourced, and the testing results. Plus the savings are incredible.† My husband and I both use Monthlees now.

As a biohacker, I was skeptical because I'm used to paying an arm and a leg for supplements. But the quality is legit — these are premium formulas† at wholesale prices. The membership pays for itself in my first order every month.
