PHASE Plastic Surgery & Longevity
PHASE Plastic Surgery & Longevity is Dr. Richard Baxter's practice in Mountlake Terrace, north of Seattle. It measures your biological age two ways, with the TruDiagnostic epigenetic test and with GlycanAge, then prescribes against those numbers. Therapeutic plasma exchange, Niagen NR IV infusions and named peptides sit beside a full plastic surgery practice with an accredited theatre on site.
