Whenever possible, after the product is dissolved, you should apply it to your experiment on the same day. However, if you need to do pre-experiment in advance, or if you need to completely dissolve it, we suggest that you store the solution in an aliquot in a sealed vial at -20℃. Usually, these can be used for up to two weeks. Before use, before opening the sample bottle, we recommend that you balance the product to room temperature for at least 1 hour

Key Products

We specialize in multiple peptide product lines, covering weight‑management peptides, pharmaceutical‑grade peptides, cosmetic‑use peptides and custom‑synthesized peptides. Our key weight‑loss peptide portfolio includes Semaglutide, Tirzepatide, Retatrutide and more related compounds.

Clinical Performance

Retatrutide has exhibited impressive therapeutic outcomes in clinical investigations. Data from a recent Phase 3 clinical trial revealed pronounced weight‑loss effects among subjects administered Retatrutide. Within a 48‑week treatment cycle, test participants achieved an average body‑weight reduction of as much as 15%, outperforming many currently available anti‑obesity medications.

Beyond weight‑lowering effects, Retatrutide delivers positive impacts on cardiovascular risk profiles. It helps optimize blood pressure, lipid parameters and inflammatory biomarkers, which in turn lowers the overall likelihood of cardiovascular‑related disorders.

Research

Class:
Actin-sequestering protein / 43-amino-acid peptide

Status:
Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

Mechanism:
A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

Activity note:
Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
