Marcus R. is a 44-year-old emergency medicine physician in Austin who had spent roughly $520 a month on a supplement protocol he'd optimized over three years — a stack that included everything from lion's mane and NMN to peptides he sourced from a compounding pharmacy. He wasn't a casual buyer. He had a spreadsheet. He tracked biomarkers quarterly. And still, when he ran his HRV on Garmin every morning, he was averaging a 47 — decent for his age, but not where he wanted to be. His sleep efficiency hovered around 79%, and post-call recovery was slow enough that he'd stopped exercising on the days after overnight shifts.

"I told myself I'd try the Rainier for 30 days and if I didn't see measurable changes I'd return it. I didn't return it." Marcus bought the Peak Rainier — the single-person, Canadian red cedar full-spectrum model with the front-facing medical-grade RLT panel — and started using it in his garage, plugged into a standard 120V/15A outlet. No electrician, no construction project. Within the first two weeks, he noticed the shift in sleep architecture before he saw it in the data. "I was falling asleep faster. I was waking up less. My wife noticed before I did."

"At 90 days: HRV up to 61. Sleep efficiency averaging 87%. I cut my supplement spend by 60% — kept the basics, dropped everything that couldn't compete with this. The math was obvious and embarrassing. I'd been spending $500 a month on things with far weaker evidence than a machine I'll have in my home for 20 years. I wish I'd made this decision at 35 instead of 44."

Danielle K. is 38, runs a seven-figure marketing consultancy in Chicago, and had been managing psoriatic arthritis for six years. She wasn't looking for a miracle. She'd done the research on infrared therapy, knew about the Laukkanen data, had read through the clinical literature on heat stress and systemic inflammation. What she hadn't found was a sauna company that felt like it understood her — someone who needed a real product, with real specs, that actually ships when they say it will, with a customer service team that picks up the phone.

"I'd looked at Clearlight. I'd looked at Sunlighten. Clearlight wanted extra money for a red light panel that was essentially a standalone unit bolted on. Sunlighten's mPulse had a customer complaint I kept seeing — the temperature wouldn't get above 119°F. That's not therapeutic range. Peak had the specs I needed and every model with full-spectrum infrared includes the RLT panel standard." She chose the Peak Everest — the two-person hemlock model — so her husband could join her for evening sessions. The 120V/20A outlet required a quick electrician visit that ran $180 and took an afternoon.

"Within 45 days I could go up and down stairs in the morning without bracing myself on the railing. That sounds like a small thing. It's not a small thing. My rheumatologist noted the reduction in my inflammatory markers at my next appointment. I still take my prescribed medications. But the sauna changed my baseline in a way that five years of expensive supplements never came close to doing."

James T. is 51 — a commercial real estate developer in Denver, triathlete, father of three. He's the kind of person who already knew the research, already valued health optimization, and had already built a home gym that looked like a mid-tier commercial facility. He wasn't a skeptic about the sauna. He was a skeptic about whether he'd actually use it. "I've bought equipment before. I know how this goes. It's a coat rack in three months." He'd seen the data on equipment abandonment. He asked Peak directly: what makes this different?

The answer was the Peak Wellness Club — a guided session system included with every purchase, with a 60-day free trial included from day one. Specific protocols. Goal-based programming. Whether you're coming in after a hard training day for recovery, building a morning cortisol-regulation habit, focusing on cardiovascular adaptation, or using the RLT panel specifically for skin and tissue recovery — there's a structured protocol. Not a PDF you downloaded once. An ongoing system. "That answer was what made me pull the trigger. Not the specs — the commitment that they'd built a system to keep me using it."

James bought the Peak Matterhorn — the three-person cedar full-spectrum model with dual RLT panels, sized for him, his wife, and occasional post-training sessions with his adult son. It required a 240V/20A dedicated circuit. An electrician handled it in a half-day. "I'm averaging 4.8 sessions per week at five months in. I've never done that with any piece of equipment I've owned. The Wellness Club is why. The data shows Peak members average 4.2 sessions per week. I believe it. The program makes it happen."
