Hair Loss. Depression. Muscle Loss. Are GLP-1 Drugs Destroying Your Body?

GLP drugs are causing depression. Hair loss. Muscle wasting. Hormone crashes. Gallbladder problems. Chronic fatigue. Brain fog. Electrolyte imbalances. Nutrient depletion. Emotional flatness. And if you read enough headlines, you start to wonder how anyone taking them is still alive. Every week there is another article or viral post warning that these medications are quietly wrecking people. People losing their hair. People losing muscle. People feeling depressed. People feeling exhausted. The story always sounds the same. A miracle drug turned hidden disaster. See what I did there. That is exactly how click bait works. Start with the scariest possible framing

What Is Actually Powering SLU-PP-332? If It’s Not Dopamine, Why Does It Feel Like Rocket Fuel?

I was listening to a podcast from Andrew Huberman on dopamine yesterday while driving back from getting lab-work and it got me thinking. SLU-PP-332 gives me pretty insane energy, so I started wondering if it’s actually elevating dopamine or if it’s running off a completely different pathway. Here’s what I found. SLU-PP-332 is described in the literature as an ERRα agonist. ERRα is a nuclear receptor heavily involved in mitochondrial biogenesis and oxidative metabolism. In simple terms, it pushes your cells to become more efficient at producing energy, especially through fat oxidation and endurance related pathways. There’s no evidence that

The Part of GLP Weight Loss Nobody Plans For

Most people start GLP tools focused on one thing. Losing the weight. And to be fair, that part usually works. Hunger quiets down. Decisions feel easier. The scale moves in the right direction. It feels like the hard part is over. That assumption is where people get blindsided. The real risk with GLP use is not that the medication stops working. It is that people quietly build their entire plan around uninterrupted access, stable pricing, and permanent suppression, without ever stopping to ask what happens if any of that changes. Because eventually, something always does. This is not about fear

GLP 1 and Alcohol Use

How This Showed Up in My Own Life Before I ever started GLP 1s, I remember hearing something that sounded more like common sense than advice. If you are going to use these, it is probably wise not to drink. This was several years ago, long before the current wave of attention, and it came from people who had already been on them and were comparing notes. Once I started, I understood exactly what they meant. Alcohol did not become off limits or unpleasant. It simply stopped having a pull. The urge faded, the anticipation never showed up, and drinking

How Do You Actually Track What You’re Taking?

I still use good old fashioned Google Sheets to track everything. Nothing fancy. I log doses, timing, compounds, reactions, and notes. I’ve got spreadsheets going back years, which means I can look at dosage changes, patterns, and how my body actually responded over time instead of relying on memory or how I feel about it today. In the actual sheet, everything is laid out horizontally by date. Each day is a single row. That makes it easy to scan across and see exactly what I took, then line that up with weight changes, symptoms, recovery, sleep, or mood. It’s simple,
