GIP injections for weight loss
Juniper members are 4.5x more likely to achieve significant weight loss than with medication alone [1]

These hormones work to reduce cravings, make you feel fuller for longer and improve blood sugar levels while also aiding fat loss and preventing fat gain. [1]
The active ingredient in Mounjaro, called tirzepatide, is the first dual GLP-1 and GIP receptor agonist and, according to clinical trials, is the most effective weight loss treatment currently available, with an average of 20.9% body weight loss. [2][3]
How Mounjaro works
How much weight can I lose with Mounjaro?
The weight loss outcomes experienced in clinical trials of Mounjaro are impressive.
A 2022 study of over 2,500 people found that those using GLP-1/GIP treatment lost up to 20.9% body weight after 72 weeks.[4]
Mounjaro vs Wegovy for weight loss
Another weight loss injection you’re probably familiar with is Wegovy. And, while it’s often compared to Mounjaro, there are clear differences between these weight loss medications.
While Mounjaro contains the GLP-1 and GIP hormones, Wegovy mimics just the GLP-1 agonist and as a result, the weight loss outcomes differ between the medications. Mounjaro also tends to have fewer side effects for users when compared to Wegovy.
There are currently no published head-to-head trials directly comparing the weight loss medications, but when looking at the respective clinical trials, patients using GLP-1 and GIP treatment achieved 20.9% body weight loss at 72 weeks versus 14.9% body weight loss at 68 weeks for those on GLP-1 treatment.
Although, it’s important to note that Wegovy still delivers excellent weight loss outcomes, but sits just slightly below Mounjaro in projected weight loss.
You gradually increase your dose every 4 weeks, but you don’t necessarily have to increase to the highest dose if you’re experiencing success at your current strength.
Your prescriber will advise you on increasing your dose and what strength is best for your maintenance dose.
