Retatrutide (Reta)

≥ 99.4% (RP-HPLC) 20mg Lyophilized Cake (2 Vials Pack) Metabolic / Tri-Agonist
Triple GIP / GLP-1 / Glucagon Receptor Agonist Verify Batch

1. What It Does (Mechanism)

Engineered tri-agonist activating GIP, GLP-1, and Glucagon receptors concurrently. Elevates hepatic mitochondrial energy oxidation while suppressing metabolic intake signaling.

2. Why It Is Studied

  • Adiposity, metabolic kinetics, and hepatic lipid clearance models.
  • Thermogenic brown-fat and mitochondrial activation research.
  • Comparative tri-agonist vs dual-agonist receptor affinity studies.

3. Lab Preparation Protocol

Reconstitute using sterile Bacteriostatic Water (BAC) along the glass wall. Store reconstituted solution at 2°C – 8°C. Do not freeze once reconstituted.

Tirzepatide

≥ 99.2% (RP-HPLC) 15mg Lyophilized Cake Metabolic / Dual-Agonist
Dual GIP / GLP-1 Receptor Agonist Verify Batch

1. What It Does (Mechanism)

Synthetic dual incretin peptide enhancing glucose-dependent insulin dynamics, gastric transit slowing, and central hypothalamic satiety modulation.

2. Why It Is Studied

  • Dual incretin receptor cooperativity and glycemic signaling cascades.
  • Pancreatic beta-cell cytoprotection in cellular stress models.
  • Cardiometabolic pathway biomarkers and lipid profiles.

3. Lab Preparation Protocol

Introduce diluent gently; swirl smoothly without foaming. Protect dry and reconstituted vials from direct UV light.

Semaglutide

≥ 99.5% (RP-HPLC) 5mg Lyophilized Cake Metabolic / Incretin
Selective Long-Acting GLP-1 Receptor Agonist Verify Batch

1. What It Does (Mechanism)

Modified GLP-1 analog with Aib-8 substitution and hydrophilic spacer fatty diacid for high albumin binding affinity and extended in-vitro stability.

2. Why It Is Studied

  • Long-acting GLP-1 central nervous system signaling pathways.
  • Systemic vascular inflammation and endothelial markers.
  • Renal tissue cytoprotection in metabolic research assays.

3. Lab Preparation Protocol

Dissolve under aseptic laminar conditions. Preserve cold strictly at 2°C – 8°C.

BPC-157 (Pentadecapeptide)

≥ 99.7% (RP-HPLC) 10mg Lyophilized Cake Cytoprotective / Cellular Repair
Angiogenic & Cytoprotective Repair Pathways Verify Batch

1. What It Does (Mechanism)

Stable 15-amino acid sequence that upregulates VEGFR2 (Vascular Endothelial Growth Factor Receptor 2) and triggers the FAK-paxillin focal adhesion pathway.

2. Why It Is Studied

  • Tendon, ligament, and fibroblastic cellular migration assays.
  • Nitric oxide (NO) system modulation during acute tissue stress.
  • Gastrointestinal mucosal membrane integrity research.

3. Lab Preparation Protocol

Reconstitute with 1.0ml to 2.0ml BAC water. Lyophilized powder stable up to 36 months at -20°C or 24 months at 2°C – 8°C.

TB-500 (Thymosin Beta-4)

≥ 99.1% (RP-HPLC) 10mg Lyophilized Cake Cytoprotective / Tissue Remodeling
Actin Regulation & Cellular Tissue Remodeling Verify Batch

1. What It Does (Mechanism)

Synthetic fraction of the actin-sequestering protein Thymosin Beta-4. Binds monomeric G-actin, accelerating endothelial migration and tissue remodeling.

2. Why It Is Studied

  • Endothelial cell recruitment and capillary formation assays.
  • Myofibrillar regeneration and skeletal fiber remodeling.
  • Reduction of acute oxidative stress and inflammation markers.

3. Lab Preparation Protocol

Slowly trickle bacteriostatic solvent; swirl gently until clear. Store cold at 2°C – 8°C.
