Ten research categories, every compound we carry, and the mechanism each one is studied for. All material is supplied for laboratory research use only.

Weight loss

Incretin analogs, amylin agonists, and metabolic inhibitors studied for fat loss and satiety.

  • Mazdutide

    GLP-1 and glucagon receptors.

  • Cagrilintide

    Amylin analog, works as CNS satiety. Additive effect with GLP-1s.

  • 5-amino-1MQ

    NNMT inhibitor, supports fat loss, decreases fat cell size.

  • AOD9604

    Fat cell breakdown — lipolysis.

  • Survodutide

Quality standards

Four checkpoints between synthesis and your bench

HPLC analysis

Every batch is run on high-performance liquid chromatography to confirm ≥98% purity before it is released.

Mass spectrometry

Molecular weight confirmation validates peptide identity and sequence accuracy on each synthesis run.

Third-party verification

Independent laboratories re-test our material. Certificates of Analysis ship with every order.

Sterile handling

Aseptic packaging, lyophilized vials, and insulated cold-pack transit protect stability end to end.
