What do GLP-1s, Cerebrolysin, Selank, and bioregulators all have in common? They're the peptides Nadia Elkhatib has spent years researching — and now uses in her own home for herself, her husband, and her 21-year-old son Jimmy, who has autism.

In this solo deep-dive, Nadia breaks down the world of peptides and bioregulators from the ground up: what they are, how they work, the rules she follows to use them safely, and the specific compounds that have made the biggest difference for her family. This isn't a theoretical overview. It's the real protocol, with real results — and the honest nuances about what she won't give Jimmy, and why.

You'll learn why GLP-1s are far more than weight loss drugs (brain protection, neuroinflammation, MCAS, and cardiovascular health), why Cerebrolysin may be one of the most powerful neuro-repair tools for autism families, how Selank quietly became her go-to for Jimmy's anxiety, and how bioregulators fit into the long-game picture of cellular health and longevity.

Topics covered: peptides vs. bioregulators, GLP-1 agonists (semaglutide, tirzepatide, retatrutide), GLP-1s for MCAS and neuroinflammation, BPC-157, KPV, GHK-Cu, the GLOW and KLOW stacks, HGH secretagogues (ipamorelin, tesamorelin), Thymosin Alpha-1, Selank for autism anxiety, Cerebrolysin for brain repair, bioregulators 101, dosing rules, cycling principles, and why working with a knowledgeable practitioner is non-negotiable.

Whether you're an autism parent curious about biohacking, an adult on the spectrum looking for functional medicine tools, or a caregiver trying to optimize your own biology — this episode is a comprehensive starting point.

Key Takeaways

1. Peptides are signalers, not forcers. They work with your body's natural biology — which is why they tend to have fewer side effects than traditional pharmaceuticals when used correctly.
2. The three non-negotiable rules: Always cycle (4–12 weeks on, then a break), avoid excessive doses (find the minimum effective dose), and work with a practitioner who actually understands peptides.
3. GLP-1s are system-wide signaling peptides — not just weight loss drugs. The research on neuroinflammation, Alzheimer's, MCAS, cardiovascular disease, and gut-brain signaling is significant and often overlooked.
4. Jimmy's MCAS responds to microdose tirzepatide because mast cells have GLP-1 receptors. When a GLP agonist binds those receptors, it signals the mast cells to calm down. Not everyone with MCAS tolerates it — slow titration is essential.
5. Cerebrolysin is not a casual intervention. It requires practitioner guidance, a stable foundation, and intentional cycling. But for autism with verified neuroinflammation, it may be one of the most meaningful tools available.
6. Selank has been one of the gentlest and most effective tools for Jimmy's anxiety. Subcutaneous injection worked better than intranasal for him. It supports dopamine metabolism and BDNF without addiction risk.
7. Bioregulators work slowly and systemically — don't expect one-to-one symptom responses. Think of them as long-game organ support and cellular health, not acute interventions.
8. Prepare the terrain first. Peptides amplify your lifestyle. Sleep, nutrition, movement, and stress management come first. They don't replace any of it.

Nadia Elkhatib is a health researcher, biohacker, and the host of Biohacking Autism. With a master's degree in Computer Science and years of experience in Silicon Valley, Nadia brings a systems-thinking approach to complex health challenges. Her journey into functional medicine and biohacking began over two decades ago while navigating autism alongside her son, Jimmy — an experience that transformed her understanding of what's possible when you move beyond conventional approaches and start asking "why is the body struggling?" Today, Nadia is dedicated to sharing cutting-edge protocols, expert insights, and practical strategies with families who refuse to settle for "there's nothing more we can do.”
