Tirzepatide - Dragon Pharma

Buy Tirzepatide Peptide 5 and 10 mg by Dragon Pharma at XSteroids. Tirzepatide is a dual GIP and GLP-1 receptor agonist peptide, the most studied metabolic peptide of its class. Dragon Pharma supplies it as 5 mg and 10 mg lyophilized vials. This guide covers what tirzepatide is, how it works, the dosing used in clinical trials and how the research vials are reconstituted.

Tirzepatide is a prescription medicine in its approved form (Mounjaro, Zepbound) and a research peptide in the vial format sold here. The information below is educational only.

About Tirzepatide Peptide by Dragon Pharma

Tirzepatide was developed by Eli Lilly as a single molecule that activates two incretin receptors at once: GIP and GLP-1. It is approved for type 2 diabetes and for obesity, and it is injected subcutaneously once a week. Its long action comes from a fatty diacid side chain and high affinity for albumin, which slows clearance and produces an elimination half-life of about five days.

Dragon Pharma offers two vial strengths: Tirze-Pep 5 mg and Tirze-Pep 10 mg, both lyophilized powders for reconstitution. Choose the strength on this page.

How Tirzepatide Works

Mechanism of Action

GIP and GLP-1 receptors are involved in insulin secretion and appetite regulation. Activating both increases glucose-dependent insulin release, slows gastric emptying and reduces food intake, which together lower body weight. Oral bioavailability is negligible, which is why the peptide is given by injection.

Weight and Metabolic Data

In the SURMOUNT-1 trial, weekly dosing for 72 weeks produced mean weight changes of -15.0% at 5 mg, -19.5% at 10 mg and -20.9% at 15 mg, against -3.1% on placebo. A 10 mg dose also reduced insulin resistance by roughly 8% by HOMA2-IR. Weight typically returns after treatment stops, which is why clinical use is long-term.

Tirzepatide Dosage and Reconstitution

Clinical Tirzepatide Dosage

Approved protocols escalate slowly: 2.5 mg once weekly for four weeks, then 5 mg, with further steps to 10 and 15 mg depending on response and tolerance. The slower the escalation, the lower the gastrointestinal burden. The 5 mg and 10 mg vials match the most common maintenance steps in that schedule.

Escalation and Tolerance

Dose escalation is not cosmetic. In the phase II diabetes trial, discontinuation because of side effects rose from 5.1% at 5 mg to about 25% at 15 mg, and the most frequent complaints were nausea, diarrhea and vomiting. That is why clinical protocols move in 2.5 mg steps and only after a full four-week block at the previous level.

What to Monitor

Because the peptide lowers appetite and slows gastric emptying, hydration, protein intake and blood pressure are worth tracking, not just weight. Blood work that includes glucose, HbA1c and liver enzymes gives a fuller picture than the scale alone, and any persistent severe abdominal pain should be treated as a medical issue rather than a dosing problem.

Reconstitution

The lyophilized powder is dissolved in bacteriostatic water using sterile technique. The dilution ratio sets the concentration: how much water is added determines how many units on an insulin syringe correspond to a given amount of peptide, so the calculation is done before the first dose rather than guessed. Mixed solution is kept refrigerated.

Tirzepatide in Cutting and Metabolic Stacks

Anyone researching tirzepatide alongside a cutting cycle should be aware of how it stacks with stimulant-based fat burners such as Clenbuterol or thyroid hormones like T3, because appetite suppression and metabolic rate changes compound. Where a cycle is involved, the hormonal base still matters, and recovery after it is planned with HCG and a SERM. Blood work and blood pressure monitoring remain the deciding tools.

Tirzepatide Side Effects and Precautions

The most common effects are gastrointestinal: nausea, vomiting, diarrhea, constipation, abdominal discomfort and reduced appetite, and both frequency and discontinuation rates rise with dose. Dizziness and hypoglycemia are also reported. Tirzepatide is contraindicated with a personal or family history of medullary thyroid cancer or MEN2. Pancreatitis has been reported after starting treatment, so persistent severe abdominal pain needs medical attention. This product is supplied as a research peptide and is not intended for self-treatment.

Storage Instructions

Store the lyophilized vials in a cool, dry place away from direct light before reconstitution. After mixing with bacteriostatic water, keep the solution refrigerated and use it within the recommended period for peptide solutions. Keep vials out of the reach of children. Lyophilized peptide powder is stable for long periods when kept dry, cold and dark, while any solution that has been mixed is far less forgiving: repeated temperature swings and exposure to light degrade it quickly, and a cloudy or particle-containing solution should be discarded rather than used. Logging the reconstitution date on the vial is a simple habit that prevents guessing later.
