Limitless Biotech VIP Program


The VIP Program gives customers access to exclusive, hidden products that aren’t available in the public storefront. This includes certain peptides and compounds that are restricted for compliance or liability reasons (such as GLP-1 analogs like Semaglutide and others).


How It Works

  1. Sign Up for VIP Access
  • Customers must first register with the VIP Registration Link.
  • Once registered, they can log in to see the full product catalog.
  1. Access Hidden Products
  • VIP-only products don’t appear in search.
  • They are viewable only when logged in, usually by scrolling through the shop page in alphabetical order.
  1. Unlock Discounts on Most Items
  • After logging in, customers can apply your ProBio15 code for 15% off eligible products.
  • Non-coupon-eligible products remain full price (e.g., some VIP offerings).
  1. Long-Term Savings & Tracking
  • Creating a VIP account activates 180-day cookie tracking.
  • Even if they forget to use the code, the affiliate link ensures commissions and discounts stay tied to you.
