Purity and Customer Service

Rated 5.0 out of 5
December 25, 2023

NuScience hits the high bar with not only purity, but the customer service is beyond anything I have experienced in my 52 years of life!! First of all, I have purchased Tirz and Sema from multiple places. The purity of NuScience Peptides is definitely above all the others I have used this far and that includes a compound pharmacy where I paid dearly. The customer service? Holy Moly, the customer service is top notch! I live one town over from the warehouse. Given USPS is not the best and sends packages around and around, NuScience said they would take my package directly to my towns post office! But then on the way to the post office, he realized he would be passing my address so he hand delivered the package the very next day!! What?!? I have ordered more since then and he has taken the package to my town post office to ensure I get it in a timely manner. NuScience has also honored my misunderstanding on a promotion! I can’t say enough, but I can say I will never use any other company for my peptides!


Thank you NuScience

We bought different products for 2 family members researching different products. Both have been successful in their research and their goals. We ordered on a Sun and had it on Wed. Packing was great and shipping was fast. We were confused about payment method and they ANSWERED their phone!!!

We will be long-term customers.

Tirzepatide Peptides: Redefining Health Management

Discover the transformative power of Tirzepatide peptides. Engineered for research purposes, these innovative solutions are tailored for managing type 2 diabetes mellitus, offering a dual-action approach to regulate blood sugar and combat obesity. Explore the exciting possibilities of Tirzepatide peptides crafted for research.These special solutions are made to help scientists study type 2 diabetes and tackle obesity.

Description – Tirzepatide

Tirzepatide is a 39-amino acid linear polypeptide which is conjugated to a C20 fatty diacid moiety via a linker connected to lysine-20. It is a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 agonist used for the management of type 2 diabetes mellitus. It has a role as a glucagon-like peptide-1 receptor agonist, an anti-obesity agent, a hypoglycemic agent, a gastric inhibitory polypeptide receptor agonist and an incretin mimetic.

Glucose Dependence

Tirzepatide is a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Dual GIP/GLP-1 agonists gained increasing attention as new therapeutic agents for glycemic and weight control as they demonstrated better glucose control and weight loss compared to selective GLP-1 receptor agonists in preclinical and clinical trials. This peptide comprises a 39 amino acid linear synthetic peptide conjugated to a C20 fatty diacid moiety. Its protein sequence was based on the sequence of endogenous GIP, and its pharmacological action on GLP-1 receptors is comparable to endogenous GIP; however, the long half-life of tirzepatide allows for once-weekly dosing. Tirzepatide was approved by the FDA on May 13, 2022, for the treatment of adults with type 2 diabetes, making it the first and only GIP and GLP-1 receptor agonist for this indication. On September 15, 2022, tirzepatide was also approved by the European Commission.
Tirzepatide also met all key secondary objectives, which included reduction in A1C and other cardiometabolic parameters. 41.4% (10 mg) and 51.8% (15 mg) of people taking tirzepatide achieved at least 15% body weight reduction compared to 2.6% of those taking placebo. Reduction in A1C compared to placebo was similar to the SURPASS trials in adults with type 2 diabetes. Study participants had a mean baseline body weight of 222 lb. (100.7 kg) and baseline A1C of 8.0%
Tirzepatide is an agonist of the receptors of two insulin-sensitizing polypeptides, GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide 1), that is used for type 2 diabetes. It has not been linked to elevations in serum aminotransferase levels during therapy or to episodes of clinically apparent liver injury.
