About the Product

About Reta-Tik™

Triple-Receptor Action · GLP-1 · GIP · Glucagon · Appetite Signaling · Energy Metabolism

BEYOND A SINGLE TARGET. THREE METABOLIC PATHWAYS.

The triple-receptor concept behind Reta-Tik™ brings together GLP-1, GIP and glucagon receptor activation in a single investigational molecule. These pathways are involved in appetite regulation, glucose control and energy metabolism, creating a distinct approach to metabolic science.

Beyond Dual-Receptor Signaling

Tirzepatide activates GLP-1 and GIP receptors. The triple-receptor approach adds glucagon receptor activation.

That third target is the defining difference. In preclinical studies, glucagon receptor activation contributed to increased energy expenditure, alongside reduced food intake associated with incretin receptor activation. A broader mechanism does not, by itself, prove better clinical results.

Clinical Data That Commands Attention

A 2023 phase 2 trial published in The New England Journal of Medicine, involving 338 adults with obesity or overweight and a weight-related condition, reported mean body-weight reductions in the 12 mg study group of:

17.5% at 24 weeks

24.2% at 48 weeks

The corresponding placebo reductions were 1.6% and 2.1%. These percentages are study-group averages under controlled conditions, not guaranteed individual outcomes.

For context, the separate SURMOUNT-1 trial reported 22.5% mean body-weight reduction at 72 weeks in the tirzepatide 15 mg group, using an analysis estimating outcomes with continued treatment.

More Than Appetite Alone

Appetite is one part of the metabolic picture.

The triple-receptor approach examines how food intake, glucose regulation and energy expenditure interact. Its distinguishing feature is the combination of incretin signaling with glucagon receptor activity, rather than a focus on a single biological target.

Reta-Tik™. Triple-receptor science. A distinct metabolic approach.

Research Applications

These experimental applications focus on understanding biological mechanisms involved in metabolic signaling and energy regulation.

Storage Guidelines

To maintain product integrity, proper storage conditions are recommended throughout handling and use.

Unreconstituted (lyophilized) peptide

  • Store at 2–8°C (in the fridge) for short-term use
  • For extended storage, keep at -20°C or below (in the freezer)
  • Protect from direct light and moisture

Reconstituted solution

  • Store at 2–8°C and use within a limited timeframe
  • For longer-term storage, aliquoting and freezing at -20°C is recommended
  • Avoid repeated freeze-thaw cycles, as this may affect peptide stability

Worldwide delivery in 3–5 days.

Peptik orders are prepared with secure handling and fast logistics for international customers.

  • International shipping within 3–5 days
