What It Is
TB-500 is a synthetic piece of thymosin beta-4, a protein that helps cells migrate to where repair is needed and keeps inflammation in check. Where BPC-157 works locally, TB-500 works everywhere at once.
Who It Suits
Stiffness and slow healing across several joints, recovery after a hard season, and injuries you cannot inject near. Most people pair it with BPC-157 ($299 stack); on its own it suits whole-body recovery.
How It Is Used
Subcutaneous injection two to three times a week for four to eight weeks, then a break. $229 a month. Injection-site redness and a brief head rush if injected fast are the common side effects. Not FDA-approved; compounded by prescription. Banned in tested sport.
How to Get It
At Zen IV Spa every program is prescribed by our medical director, a licensed physician, after a $50 video consultation and labs drawn at your home. Medication ships overnight anywhere in New York or New Jersey from an FDA-registered 503A pharmacy, and a nurse can come for the first dose.
