Editorial note: RED FLAG — DOWNGRADED Tier 2 -> Tier 3, recommend EXCLUDE from a pure-longevity directory. The CLINIC is real and heavily reviewed (Google 4.9/807, Trustpilot 5.0/259, Reddit-positive) — BUT every independent source (Reddit is exclusively r/HairTransplants, Trustpilot reviews, GBP) concerns HAIR TRANSPLANTATION, not longevity. Both named doctors' verifiable specialty is hair restoration + medical aesthetics (Yalvaç independently confirmed as hair/aesthetics, not longevity/internal-medicine). The longevity 'Youngevity Reset' vertical's ONLY sources are the clinic's own SEO landing pages ('The Best Longevity Clinic in Turkey 2026') + commission aggregators (Bookimed, PlacidWay) — ZERO independent longevity corroboration. This is a marketing-front pattern for the longevity vertical specifically, and it violates the niche's 'NOT hair providers' exclusion. The strong reviews validate the hair clinic, NOT a longevity practice.
