4Ever Young plans Allen opening, bringing longevity wellness services to Collin County
4Ever Young is set for an Allen location on N. Custer Road, betting on Collin County’s affluent, fast-growing customer base for longevity and preventive care.

Allen is set to get another health-focused business as 4Ever Young moves into 1480 N. Custer Rd., Suite 160, bringing hormone optimization, weight management, peptide therapy, advanced diagnostics, aesthetic treatments and personalized wellness planning into the city’s growing wellness mix. The company said the development agreement was signed for a fall 2026 opening.
The Allen site is being developed by Hamid and Fatana Herzai through Texas Longevity Lab, a local corporate vehicle filed in Texas on Aug. 11, 2025, with Hamid Herzai listed as the registered agent and sole principal. For Collin County, the move adds a longevity and preventive-care concept aimed at residents who want more than a one-time med spa visit and are willing to pay for ongoing, data-driven wellness services.
That model appears to fit Allen’s market. The city’s estimated population reached 113,447 on July 1, 2025, while Collin County climbed to 1,297,179, reinforcing why national franchise brands keep pushing north into the suburbs. Allen’s median owner-occupied home value was $464,100 in 2020-2024 Census data, its bachelor’s degree rate was 57.5 percent and broadband subscription stood at 97.2 percent, markers that suggest a customer base comfortable with digitally marketed, membership-based health services. Collin County’s health care and social-assistance receipts were estimated at $12.37 billion in 2022.

4Ever Young was founded in 2014 in Boca Raton, Florida, and says it now operates in 120-plus U.S. locations. Earlier company materials said it had 110 franchise units sold and was operating in 14 states, underscoring how quickly the brand has expanded as anti-aging and wellness services have moved from niche offerings to a mainstream suburban retail category. The company’s Boca Raton materials say it relies on advanced diagnostic methods and customized treatment plans to help patients maintain vitality and wellness rather than simply treat symptoms.
For Allen, the project fits a broader commercial pattern: new retail, medical and wellness concepts continue to cluster around northward growth corridors where higher incomes, strong home values and a dense suburban population can support specialty services. In a county already shaped by healthcare spending and fast household formation, 4Ever Young is betting that preventive wellness has room to grow.
