What it is

The newest addition to our pre-filled cartridge range: Retatrutide 30mg and Tirzepatide 30mg combined into one pre-filled cartridge. Developed in response to client feedback — clients wanted the benefits of Retatrutide while also experiencing the stronger, more consistent appetite control they had come to expect from Tirzepatide. So we listened, and built RT Mix 30/30.

Key benefits

  • Maximum fat loss — two of the most talked-about compounds for body-composition goals, combined in one cartridge
  • Next-level appetite suppression — designed for the stronger, more consistent appetite-control effect clients asked for
  • Muscle preservation — built for clients who want fat loss while holding on to lean mass
  • Metabolic optimization — retatrutide's triple-receptor action (GLP-1, GIP and glucagon) alongside tirzepatide's dual action (GLP-1 and GIP)
  • Enhanced energy & performance — formulated for clients chasing output, not just the scale
  • Advanced well-being — one cartridge, one simple routine, less to manage

How it works

Retatrutide works differently because it activates three receptors — GLP-1, GIP and glucagon — while tirzepatide activates GLP-1 and GIP. Appetite suppression is only one part of the picture: some clients see changes in body weight and body composition even while still experiencing food thoughts or cravings. That's exactly why feedback matters to us, and it's what led to this new formulation. The new RT Mix 30/30 combines the different mechanisms of both compounds into one product, with a new pH profile — one of the formulation differences in this new batch. Clients using the new formulation have already reported stronger appetite suppression compared with their experience on previous batches. Contact us for product-specific details before ordering.

Who it's best for

  • Clients currently using Retatrutide 50mg
  • Clients currently using Tirzepatide 60mg
  • Clients moving over from the previous RT Mix 55mg / 110mg
  • Anyone who wants both compounds' mechanisms in a single cartridge
