Kirkland holds multiple drug synthesis and formulation patents, has founded multiple pharmaceutical companies, and is one of the few people in the world manufacturing peptides entirely on US soil, controlling every step of the synthesis process from raw amino acids to finished product. If you want to understand what is really inside your peptides and why it matters for your longevity and human performance, he is the person to listen to.    Dave and Justin go deep on why most peptides on the gray market contain dangerous residual compounds that can spike liver enzymes and cause real harm, why Chinese-sourced APIs are not always what they claim to be, and how a new generation of needle-free delivery systems including microneedle patches and auto-injectors is making peptide therapy accessible to anyone serious about longevity and human performance. They also cover how AI and functional medicine are converging to make peptide protocols personalized based on genetics and microbiome status, why the thymus gland is one of the most overlooked anti-aging targets i… ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/the-human-upgrade-biohacking-for-longevity-performance-1031629/episodes/peptide-power-without-needles-smarter-dosing-for-longevity-justin-kirkland-1477/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/the-human-upgrade-biohacking-for-longevity-performance-1031629/peptide-power-without-needles-smarter-dosing-for-longevity-justin-kirkland-1477.md` — Read the agent-friendly Markdown representation of this episode resource.
