Why delivery method matters more than most people realize ••
In this clip, we’re breaking down iontophoresis vs. injections when it comes to peptide delivery - purely from a pharmacokinetic + delivery standpoint.
Here’s the key concept y
Many commonly discussed peptides like BPC and TB500 have very short half-lives (often ~2 hours), meaning levels in the body drop rapidly after administration. NAD is even shorter, often around ~1 hour.
With traditional injections, this can look like a quick spike followed by rapid clearance.
With an iontophoresis patch, delivery happens gradually over 12+ hours, offering a sustained exposure window rather than a single peak.
Why this matters
Continuous delivery vs. rapid clearance
V Potentially improved utilization over time V Non-invasive, needle-free application
V A delivery option worth understanding for providers and patients alike
This isn’t about replacing clinical judgment - it’s about understanding how delivery systems impact how compounds interact with the body.
