The 4x Blend (Lipotropic) is a lipotropic research formula containing Methionine (15mg), Choline Chloride (50mg), L-Carnitine (50mg), and Dexpanthenol (5mg) in a single lyophilized vial. These components have been individually studied for their roles in lipid metabolism, methylation pathways, and fatty acid transport in preclinical research.

Preclinical studies on components for hepatic lipid export, β-oxidation, methylation (e.g., methionine-choline def. models NASH J Biol Chem; carnitine fatty acid shuttle Nutrients 2021) All findings referenced are from preclinical and in vitro studies. No approved clinical applications exist for this research compound.

Lyophilized: -80°C long-term, 4°C short-term; reconstituted refrigerate ≤30 days YourPeptideBrand Avoid repeated freeze-thaw cycles.

Peptide.co’s 4x Blend (Lipotropic) has been verified at 99.1% purity through independent third-party HPLC testing. The current batch (Lot #YPB.268, blend) includes a full Certificate of Analysis confirming identity, purity, and peptide content. All COAs are publicly available at coa.peptide.co. Testing covers HPLC purity analysis, mass spectrometry identity confirmation, heavy metals screening (<20 ppb), and microbial limits (TAMC/TYMC: 0 CFU). All products are manufactured in FDA-registered facilities in the United States.

Blend formulas: C5H11NO2S, C5H14ClNO, C7H15NO3, C9H19NO4

4x Blend (Lipotropic) is supplied as a lyophilized (freeze-dried) powder and must be reconstituted before use in research applications. The standard reconstitution solvent is bacteriostatic water (sterile water containing 0.9% benzyl alcohol). When reconstituting, direct the solvent gently along the inside wall of the vial — do not spray directly onto the lyophilized powder. Allow the compound to dissolve naturally without shaking or vortexing. For detailed reconstitution volume calculations, use the free Bacteriostatic Water Calculator or Peptide Reconstitution Calculator on Peptide.co.
