The cheap vial

## Why does research KLOW look cheaper?

-   **It is sold for research, not for you.** The label says not for human use.
-   **No prescription and no pharmacy.** Nobody reviews your history, and nobody you can check compounds it.
-   **You finish the job.** BAC water, syringes, mixing and the units math are on you.
-   **Status.** KLOW is a blend, so it is outside the HHS peptide policy of October 28, 2026 either way. Prescribed KLOW is still made by a licensed pharmacy for one patient. [Are peptide stacks legal?](https://peptides.build/legal/peptide-stacks/)
