Generic Peptides Tirzepatide 2 to 10 mg GIP GLP-1 Vials

It is a dual agonist peptide that activates the GIP and GLP-1 receptors at the same time. Chemically it follows the GIP sequence with two non-natural amino acids at positions 2 and 13, a C-terminal amide, and a lysine at position 20 linked to 1,20-eicosanedioic acid. The FDA label gives its mass as 4813.53 Da and its formula as C225H348N48O68.

No. The vials on this page are lyophilized research material for laboratory work only. The approved tirzepatide medicines are prescription products injected once weekly under medical supervision, and they carry a boxed warning. No human dose is stated or implied here, and the material is not for human or veterinary use.

Keep the sealed powder cool, dry and dark, at 2-8 C for routine work and -20 C for long-term storage, and let the vial warm to room temperature before opening because the powder takes up moisture. Dissolve it in sterile or bacteriostatic water down the vial wall and swirl gently. Keep the solution at 2-8 C for about four weeks.

The label lists gastrointestinal reactions as the most common: nausea, diarrhoea, vomiting, constipation, indigestion and abdominal pain, along with injection-site reactions and tiredness. Serious risks include pancreatitis, gallbladder disease, kidney injury from dehydration, hypoglycaemia with insulin or sulfonylureas, and thyroid C-cell tumours in rodents.

It is not on the WADA Prohibited List. WADA has placed the GLP-1 receptor agonist class, including semaglutide and tirzepatide, in its Monitoring Program, which means samples are screened to study how widely these drugs are used, and WADA has said the status stays unchanged for 2027. Monitoring is not a prohibition.

Semaglutide acts on one receptor, GLP-1, while tirzepatide activates GIP as well. The two therefore differ in receptor coverage and in the trial profiles published for each, but neither is a research material by design. In this line the comparison is run as two separate arms so the receptor count is the only variable.

All three vial sizes are listed on this page as research material with international shipping at checkout, handled in one to two days with a transit window of four to ten days. Shipping runs about 35 dollars. The U.S. domestic option is not offered on this offer, so buyers inside the United States should check the rules that apply to them.
