Rethinking Peptides for Research

Why should high-quality peptides only come in complicated, injectable formats?

Research deserves compounds that are consistent, stabilized, and easy to work with, which is why we focus on sprays, tablets, and capsules that allow for precise, pre-measured amounts that we ready to use in controlled experiments.

Quality You Can Trust

Every compound we produce is stabilized, meaning it holds its integrity during shipping without the need for cold-chain logistics. This ensures purity and reproducibility for research purposes.

Meet The Founder

Jeff S. established Stemcode out of a personal drive to make high-quality peptides more accessible to researchers in the athletic and longevity space. As a lifelong endurance athlete, Jeff has competed in marathons and triathlons and is training for his next Ironman. 

His curiosity about peptides began with their potential role in muscle recovery and building resilience. Instead of keeping that knowledge personal, Jeff envisioned something broader: building a trusted platform where researchers could access clean, dependable peptides to move science forward.

Our Commitment

Non-Injectable Formats Only

Easier handling, no sterile prep.

Accurate, pre-measured dosing

Less room for error.

Stabilized compounds

Dependable quality without cold shipping.

Transparency

COAs are always included, never hidden.

Why Stemcode Peptides?

Because research should be about results—not red tape, we exist to make accessing stabilized, non-injectable peptides simpler and faster for the research community.
