How does The Grand Slam Bundle work? What is its mechanism of action?

Reported Mechanisms — Component by Component Each section below summarizes the published mechanism of a single component. No combined mechanism is described in the literature, and none is asserted here. 1. GLP3-R / Retatrutide (30 mg) — Triple Receptor Agonism Retatrutide is described as engaging the GIP, GLP-1, and glucagon receptors with a single peptide sequence, distinguishing it from dual GIP/GLP-1 agonism and GLP-1-selective agonism.[1] Clinical pharmacology has been reported in phase 1b a

What are the research applications of The Grand Slam Bundle?

Research Applications (Component-Level) The published work behind each vial in this kit falls into the following areas. Every study listed used a single component or blend, not the bundle. Incretin and glucagon receptor pharmacology — retatrutide serves as the triple-agonist reference compound in comparisons against dual and selective agonists.[1][2] Metabolic research — phase 2 trials of the pharmaceutical formulation have been published in obesity and type 2 diabetes.[3][4] Matrix and fibrobla

What does the research summary say about The Grand Slam Bundle?

Research Summary (Component-Level) No peer-reviewed study has evaluated this three-vial bundle as a unit. The table below lists representative findings for each component individually. Full per-component data and complete reference lists are on the dedicated GLP3-R, GLOW, and CJC (no DAC) / Ipamorelin pages. ComponentRepresentative StudyReported ObservationRef GLP3-RCoskun et al. (2022) — discoveryCharacterized as a triple glucagon, GIP, and GLP-1 receptor agonist[1] GLOW / GHK-CuMaquart et al.

How should The Grand Slam Bundle be stored?

Store each lyophilized vial at -20°C (long-term). Reconstituted: -80°C for extended storage, 2-8°C for short-term use. Keep the GLOW vial away from chelators (EDTA, carnosine, Vitamin C). Reconstitute and store each vial separately.

Q: What is The Grand Slam Bundle?

Overview The Grand Slam Bundle groups three research materials, each characterized in a separate body of published work. It ships as three individual vials, two of which are themselves multi-peptide blends. GLP3-R is retatrutide (LY3437943). Coskun et al. published its discovery-to-clinical-proof-of-concept characterization as a triple glucagon, GIP, and GLP-1 receptor agonist; Urva et al. reported the phase 1b multiple-ascending-dose study; and phase 2 trials in obesity and type 2 diabetes have

Recommended Laboratory Storage Conditions — The Grand Slam Bundle (3 vials)

Lyophilized Powder: Store all three vials at -20°C for long-term stability, protected from light and moisture. The GLOW vial shows a pale-blue tint from the GHK-Cu copper complex.

Reconstituted Solution: Store aliquots at -80°C for extended periods. Refrigerated (2–8°C) solutions containing BPC-157 and TB-500 should be used promptly due to hydrolysis kinetics. Reconstitute by gentle swirling — do not vortex or shake aggressively.

GLOW Incompatibilities: Do not co-formulate the GLOW material with EDTA, carnosine, Vitamin C, or other strong chelators — these strip Cu(II) from GHK-Cu and abolish its activity.

Separate Handling: Each vial is a distinct material. Reconstitute and store each independently; there is no published stability data for pre-mixing these materials in one solution.

Component Purity: ≥98% per peptide by HPLC; identity by mass spectrometry; TFA-free preferred for biological-grade research.

Handling: Allow vials to reach room temperature before opening to prevent condensation onto the lyophilized cake. Use standard aseptic technique. Discard any solution that appears cloudy or contains particulate matter.
