Fatigue, brain fog, digestive issues, joint pain, skin changes, flares, swelling and food reactions get treated as separate problems, by different people, over years. Sometimes they are one immune pattern nobody has connected yet.

Colin Renaud, PA-C walks through what the autoimmune process actually is, the symptom cluster that should make you stop and look for a pattern, and what tends to set the immune system off, including stress, infection, mold and environmental exposure. He gets into why someone can have obvious symptoms and still not have a diagnosis, and what testing actually helps: full thyroid panels with antibodies, ANA, rheumatoid factor and anti-CCP.

He also covers what managing a flare looks like, why recovery takes the time it takes, and how gut health, nutrition, stress and trauma fit in. The episode closes with live questions from viewers.

Peptides are everywhere right now, and one of the most misunderstood tools in longevity medicine. Dr. Sasha Rose and Colin Renaud, PA-C break down what they actually are, where they may fit in a functional medicine plan, and why they are a piece of a plan rather than a shortcut around one.

Colin is direct about the problem with buying peptides online or copying a protocol from social media: it is the same one-size-fits-all thinking that frustrates people about care in the first place, and every body is different. They get into what separates chasing trends from practising longevity medicine, what has to be handled first when it comes to sleep, nutrition, strength, metabolic health and hormones, and what actually gets monitored when someone is on therapy.

They also walk through what a care plan looks like from the discovery call forward, and what patients should be cautious about.

Taking thyroid medication every day, told your labs are normal, and still exhausted, foggy and cold? Dr. Sasha Rose goes past TSH.

She covers what levothyroxine and Synthroid actually replace, why your body still has to convert T4 into active T3, and what reverse T3 does when it competes for the same receptor spots. She explains Hashimoto's and thyroid antibodies, which account for roughly 75 to 85 percent of hypothyroid cases, and walks through the fuller panel she runs: TSH, free T4, free T3, thyroid antibodies, reverse T3, iron and ferritin, vitamin D and B12.

She also gets into whether the medication is being absorbed at all, the nutrients conversion depends on, and how she tracks progress using energy, brain fog, cold tolerance, digestion, hair, mood and sleep alongside the labs.

Colin Renaud, PA-C explains why the training session is not where muscle actually gets built, what muscle does for metabolism and blood sugar, and why recovery is the part most people skip.

Muscle affects metabolism, blood sugar regulation, mobility, bone health and how resilient the body is as it ages. What body composition testing actually shows, how muscle and insulin are connected, why recovery and sleep do the building rather than the training session itself, and what protein intake really needs to look like.

Colin Renaud, PA-C and Dr. Sasha Rose work through why energy, strength, focus and recovery change with age, and why so many people are told that is simply what getting older looks like.

Patients describe the same pattern: the body and the brain feel like they are slowing down, and nobody has looked deeper into why. What muscle actually does beyond strength, why maintaining it takes deliberate attention, how hormones and thyroid markers fit in, why one lab value is rarely enough, and what a full workup looks like when someone says they feel older than they should.
