Mounjaro KwikPen – how the pre-filled injection pen works

KwikPen is a pre-filled multi-dose pen from the pharmaceutical company Eli Lilly, used to administer the medication Mounjaro. This type of pen is designed to facilitate regular dosing during medical weight loss and the treatment of type 2 diabetes. Here we go through how to handle the pen safely – from preparation to correct storage – to ensure your treatment works optimally.

Sustainable Weight Loss: How Patients Save Money with Yazen

New data proves sustainable weight loss delivers significant savings for patients.


A pan-European survey of 1,350+ Yazen patients reveals a "health dividend" where effective obesity treatment offsets its own cost. By addressing biological cravings, patients save an average of €109 on food and €50 on healthcare monthly. Findings show a natural shift away from snacks and takeaways toward nutrient-dense, mindful consumption.

Salmon bowl with rice – protein-rich and nutrient-dense

A protein-rich salmon bowl is a nutrient-dense meal that can actively support your weight loss by keeping you full, stabilising blood sugar, and preserving your vital muscle mass. By combining omega-3-rich salmon with fibre-rich vegetables, edamame beans, and whole grains, you create a balanced bowl that is both nutrient-dense and protein-rich. This guide explains exactly why these ingredients are optimal for your health, how to prepare the meal effectively for the week's lunch boxes, and the profound benefits the dish provides for your body.

Medical treatment or bariatric surgery: a new era in obesity treatment

The choice between bariatric surgery and medical treatment has changed alongside the development of new, effective medications. Today, modern GLP-1 and GLP-1/GIP receptor agonists can provide significant weight loss that, in some cases, approaches the results previously achieved primarily through bariatric surgery. Here, we look at both options from a medical perspective and describe their effects, risks, and benefits.

I’ve tried everything – why am I not losing weight?

Not losing weight despite feeling like you are doing "everything right" is rarely due to a lack of discipline. The body's biology and hormonal systems play a central role in regulating body weight and can counteract weight loss.

To achieve sustainable results, it can therefore be valuable to understand how appetite regulation and individual circumstances affect weight, as well as which evidence-based treatment options are available.

Semaglutide or Tirzepatide – which is more effective for weight loss?

Semaglutide and tirzepatide are both well-documented medications for medical weight loss. In clinical studies, tirzepatide has shown a greater average weight loss than semaglutide, but individual efficacy, tolerability, and treatment choices vary. The choice of treatment should always be based on an individual medical assessment.

Golden dose Mounjaro – safety, myths and user changes

The concept of the “Golden dose” for Mounjaro refers to the residual liquid that may remain in a KwikPen after the intended doses. Advice on using this as an extra dose is spreading on social media, but healthcare providers advise against it because the dose is not quality-assured. Extracting residual liquid can lead to incorrect dosing and increased risk of side effects. Changes in how the medication is provided aim to strengthen patient safety.

Golden dose Wegovy – myths and safety

The term “Golden dose” refers to the residual liquid that may remain in a Wegovy pen after the intended doses. Advice on using this as an extra dose is spreading on social media, but healthcare providers clearly advise against this. There is a risk of incorrect dosing as well as a risk of contamination when manipulating the pen outside of its intended use.

Ozempic prescription – medical assessment, guidelines, and laws

To obtain Ozempic, a medical assessment by a licensed doctor is required. GLP-1 analogues have revolutionized weight loss, but high demand creates questions regarding regulations and safety. Many wonder about the requirements for prescriptions and the risks of online orders. This guide explains the process within the EU and patient requirements. It is crucial to choose a regulated healthcare provider like Yazen to guarantee safe treatment and avoid unreliable sources.
