tirzepatide

99.784% HPLC
Dual agonist

Tirzepatide (LY3298176) is a synthetic 39-amino-acid peptide engineered from the glucose-dependent insulinotropic polypeptide (GIP) backbone, incorporating two non-coded α-aminoisobutyric acid (Aib) residues and a C20 fatty-diacid side chain that confers dual binding affinity at the GIP and GLP-1 receptors. In published preclinical and clinical literature it has been investigated in the context of glucoregulatory and metabolic research. Supplied lyophilized at ≥99% HPLC purity with a per-lot Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.

Best customer service I have experienced

The customer support alone deserves five stars. Every question I had was answered quickly, professionally, and thoroughly. Most companies take days to respond, but I consistently received replies within hours, and sometimes even sooner. The team made me feel like an actual person instead of just another order number. Whether I had questions about shipping or product availability, everything was handled immediately. It is rare to find a company that combines excellent service with such a seamless ordering experience. The communication and support have been outstanding, and that is a big reason why I will continue to order from them.

Quality products and good prices

Quality products and good prices. Customer service does respond, even if it is a few days late due to possible junk-mail jail.
