Unlike typical drugs with inelastic demand, the market for GLP-1s is price-elastic. Eli Lilly's CEO confirms that lowering prices directly expands the user base, creating a rare instance where capitalist incentives align with broader consumer access in the pharmaceutical industry.

High drug costs are systemic, rooted in the for-profit model's legal obligation to prioritize shareholder returns over patient affordability. This is compounded by a complex distribution chain where multiple middlemen—wholesalers, insurers, and pharmacies—each add a profit layer, inflating the final price.

The high cost of insulin isn't from manufacturing but from the complex distribution chain of wholesalers, pharmacies, and insurers. Project Insulin's core strategy is to bypass this system entirely with a direct-to-patient mail-order pharmacy model, effectively eliminating the middlemen who inflate the final price.

Aphaia's drug formulation is built around glucose, one of the most abundant and inexpensive materials on Earth. This deliberate strategic choice contrasts with complex, expensive injectables. It positions their treatment to address the 94-97% of eligible patients worldwide who cannot access or afford current therapies, creating a massive market opportunity.

The scientific knowledge to produce insulin is widespread. The primary barrier to creating an affordable biosimilar is not a scientific challenge but raising sufficient capital to navigate manufacturing and distribution, a problem addressed by Project Insulin's non-profit, fundraising-first model.

The surge in use of compounded GLP-1s, costing about half the price of branded versions, demonstrates huge untapped demand. Patients are willing to accept manufacturing and safety risks for affordability, proving price is a major barrier to adoption.

The emergence of low-cost, compounded versions of GLP-1 drugs from telehealth companies like Hims is creating significant pricing pressure on market leaders Novo Nordisk and Eli Lilly. This dynamic has pushed the pharma giants toward direct-to-consumer models with lower prices to compete.

The key catalyst for GLP-1 weight-loss drugs becoming mainstream wasn't just effectiveness, but a drastic price drop. Moving from over $1,000/month to as low as $25/month with insurance transformed the drug from a luxury good into an accessible, subscription-like product, paving the way for mass adoption.

To solve the insulin price bubble, Eli Lilly launched its own low-list-price biosimilar. However, insurers and PBMs initially refused to cover it because its low price and small rebate threatened their lucrative business model.
