Semaglutide without needles for wigtht loss

When Semaglutide is the subject of an educated conversation between people, so many questions can come to the surface, here is a brief list:
How and where do I get semaglutide?
Is it over the counter or prescription?
What is GLP-1?
Is it a hormone or peptide?
Is Semaglutide safe or are there any health complications involved?
Do I have to see the doctor or nurse for each treatment, or do I administer it myself in the comfort of my home?
Does semaglutide work better and faster than just diet and exercise?
Which semaglutide should I take, Wegovy or Ozempic?
If Novo Nordisk makes both Wegovy & Ozempic, are there any other brands?
If injectable vaccines, supplements, and medications such as insulin, growth hormone, pain medication, have been involved in clinical trials and proven to be safe to use without needles, does it mean that using a needleless jet injector for semaglutide & peptides would achieve the same results?
Many people nowadays use the needle-free jet injectors for their semaglutide subcutaneous delivery, how do we know? They are telling us what they use it for, they are asking for pen adapters and asking how to extract it from the pen.

Clinical trials have recently shown that when semaglutide of various brands currently available worldwide are used in weight loss programs, significant weight loss can be achieved.
Some of these brands are Ozempic & Wegovy.
Most, if not all, semaglutides are prescribed by a physician or endocrinologist.
The type of recommended delivery is subcutaneously, like insulin or any other growth hormone and peptides, your next question should be: Can this be achieved entirely without using needles, using a needle-free jet injector?
There are diverse types of Semaglutides, and they work in diverse ways.
Some claims are that semaglutides may help with reducing cravings, some claims are that it signals the brain that you are full and content.
Other claims are that semaglutides are suggested to slow the metabolism and they may help control blood sugar levels.
