GLP-1 Sterile Injections
GLP-1 therapy is an effective treatment for obesity. In America, approximately 42% of adults have obesity, and more than one in ten adults have severe obesity. In the United States it is an epidemic. Obesity is linked to numerous chronic diseases, including type 2 diabetes, high blood pressure, heart disease, and certain types of cancer. At Haven Rx we feel that GLP-1 agents can help combat this epidemic and help patients achieve their healthcare goals.

Vitamin B12
At HavenRx we feel that vitamin B12 is important and clinically relevant for patients that are treated with GLP-1 agents due to the known decreased vitamin B12 absorption with patients on GLP-1 therapy.
However, we also feel that not much is needed. We are not treating a deficiency we are preventing one.

Our take on preferring NOT to add GLYCINE to a GLP1 compound
Glycine is a very typical addition to GLP1 therapy. It is usually added with the hope of preventing muscle wasting from the GLP1 therapy. Muscle wasting is a valid concern for patients on GLP1 therapy. However, typical glycine doses range from 5-15 GRAMS PER DAY and it is highly bioavailable for our body to absorb orally.
The dose seen in most GLP1 compounds is 5-10 MILLIGRAMS PER WEEK! That is 7000 times less per week than typical oral dosing over a week. Therefore, the subcutaneous dose given is not significant and will not prevent any muscle wasting. We have also noticed that some patients experience more pain and irritation at the injection site when glycine is added.
​
If you do wish to take glycine to prevent muscle wasting we recommend coupling it with weight bearing exercise and that you purchase oral glycine from a reputable manufacturer. It has been known to cause drowsiness and may help some patients that are needing a good night's sleep. It is sweet and can be added as a mild sugar substitute to your favorite herbal tea.
