Active ingredient(s)

Tirzepatide

Description

KwikPen (injectable)

How does Mounjaro work?

The active ingredient in Mounjaro is called tirzepatide and it stimulates two different naturally occurring hormonal receptors: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Other weight loss injections like Ozempic and Wegovy work on GLP-1 alone, whereas Mounjaro combines with GIP to increase the weight loss potential.
GLP-1 helps to regulate blood sugar levels, which in turn talks to the brain to make you feel less hungry and prevent cravings. It also slows down the emptying of the stomach to keep you feeling fuller for longer.
GIP regulates energy balance in brain and fat cells, enhancing the GLP-1 effect of suppressing your appetite and improving sugar control.

"I've struggled with weight management for years, but after starting the Wegovy® Injectable Pen from SlimVials, I've lost over 10kg in just three months. The once-weekly injection is easy to use, and the support from the SlimVials team has been exceptional. Highly recommend!"

Emily Thompson
"The Retatrutide - Synedica® has helped me shed 8kg in two months. While the results are impressive, the cost is a bit high. Customer service was responsive, and delivery was timely. Would appreciate more affordable options."

James Walker
"Using the Mounjaro® Injectable Pen has been a game-changer. I've lost 12kg in three months without any major side effects. The pen is easy to use, and the SlimVials website is user-friendly. Fast delivery and excellent customer support."

Sarah Johnson
"I tried the Wegovy® Injectable Pen but only lost 4kg in two months. While it's effective, the results were slower than I expected. The product is of good quality, but I was hoping for more significant weight loss."

David Smith
"SlimVials provided excellent support throughout my weight loss journey. The Retatrutide - Synedica® has helped me lose 9kg in two months. The injections are easy to administer, and I appreciate the detailed instructions provided."

Olivia Brown
"The Mounjaro® Injectable Pen has been effective in aiding my weight loss, with a 7kg reduction in two months. However, I experienced mild nausea initially. The side effects subsided after a week, and the results have been worth it."
