How Microdosing Can Backfire

This week on Fat Science, Dr. Emily Cooper, Andrea Taylor and Mark Wright take a hard look at the buzz around microdosing metabolic medications—from what “microdosing” actually means to the risks of following trends without clinical supervision. The team unpacks widespread misunderstandings about dosing for drugs like Ozempic, Zepbound, and low-dose naltrexone (LDN), explains why social media advice can be dangerous, and highlights just how unique every person’s metabolic needs are.

Dr. Cooper shares patient examples and lays out the science behind hormone regulation, medication resistance, and why skipping a full evaluation could backfire. We cover why glandular extracts and testosterone supplements can disrupt your body’s natural balance and why trying to “trick” your metabolism with tiny doses can sometimes do more harm than good.

Key Takeaways:

• Microdosing means doses far below anything supplied by drug companies—it’s not the same as prescribing a lower dose within the normal range.
• Popular trends in LA and beyond push people toward self-experimentation, often with compounded drugs or unsupervised regimens.
• Taking metabolic drugs without a clinical need can weaken natural hormone production and create dependency—even with “natural” supplements.
• GLP-1s, GIPs, naltrexone, and testosterone all show very different outcomes depending on your genetics, history of dieting, childhood athletics, or use of other medications.
• More is not always better. Too high a dose can create medication resistance, while too low might “numb out” your hormone response.
• Professional evaluation, sleep, nutrition, and self-kindness remain the first line of defense for metabolic health, rather than skipping over those and heading straight to medication.
