“I was running a startup, sleeping 5 hours, and drinking 4 coffees a day just to function. Koen didn’t start with training or supplements — he started with my cortisol pattern and why my nervous system was completely fried. Six weeks in, I’m sleeping 7.5 hours, off the coffee, and actually thinking clearly for the first time in two years. The DSIP alone was a revelation.”

“I’d been using random peptides from the internet for two years — nothing consistent. Koen built me a pharmaceutical-grade stack through Eternal Wellness Center, explained exactly what each compound was doing and why the sequencing mattered. Within 8 weeks my recovery was completely different. Training at 48 with the recovery of someone 20 years younger.”

“Lost 17kg in 5 months. Not from a crash diet — from understanding why my body wasn’t letting go of fat in the first place. Insulin resistance I didn’t know I had, cortisol-driven belly fat, a thyroid running below optimal. Koen addressed all three. The weight came off as a side effect of actually fixing my biology.”

“42 years old, testosterone at 11 nmol/L, libido basically gone. My GP wanted to put me on TRT straight away. Koen’s approach was: find out why the production dropped before replacing it. Turned out my liver and gut were the root issue. 4 months addressing those — without any TRT — and I’m now at 24 nmol/L naturally. Libido is back. Energy is back. I feel like myself again.”

“I’m a surgeon. I need to operate at 100% on 5 hours of sleep when required. For 3 years I couldn’t. Brain fog, word-finding issues, decision fatigue by noon. Koen identified mitochondrial dysfunction and methylation impairment — both traceable to a gut that had been inflamed for years. Semax, NAD+, B12 protocol, gut repair. Clarity returned within 6 weeks. Nothing short of life-changing.”

“I’m 45, have three kids, and was 22kg overweight. I wasn’t looking for a magic bullet — I’d had enough of those. Koen’s PrimalScan identified my cortisol pattern, insulin resistance, and the fact that my training was actually making everything worse. Complete re-architecture of my approach. 14kg down, first time I’ve felt strong in 8 years.”

“Ruptured Achilles. Surgeons said 9–12 months. I worked with Koen through EWC on BPC-157 and TB-500 alongside the standard physio. Back running at 14 weeks. I don’t know how to explain it to people who haven’t seen it — I just know what happened.”

“I came to Koen for the biology. I didn’t expect the conversation about identity and the patterns that were keeping me stuck would hit harder than the bloodwork. The physical protocol is serious — but that ‘who are you when you stop performing’ question broke me open. Six months later I have a different relationship with my work, my marriage, and myself. The body followed.”

“28 years old and already feeling like I was operating below potential. Low energy, poor recovery, brain fog despite doing ‘everything right.’ Koen found gut-driven testosterone suppression — something I never would have connected. Three months of targeted gut repair and the right supplements, and I feel better than I did at 22.”

“56 years old. My GP told me my results were ‘normal for my age.’ Koen told me normal for my age was the wrong target. Epithalon, GHK-Cu, NAD+, and a complete metabolic overhaul. My last bloods read like someone in their late 30s. I’ve trained for 30 years. This last 18 months has been the best my body has ever felt.”
