The Harbor Health editorial team includes physicians, pharmacists, and health writers dedicated to providing accurate, evidence-based information about weight management and GLP-1 medications.
Ozempic is approved for type 2 diabetes, not weight loss. These seven alternatives are the treatments people actually weigh instead, from compounded semaglutide and tirzepatide to the two new daily pills, with the trial results behind each.
NAD+ benefits are some of the most repeated claims in longevity medicine. Here are nine, each graded by its human evidence and the form that was actually tested, because most of the data comes from oral precursors and animal studies, not from NAD+ injections.
One is the antioxidant itself. The other is the raw material your cells use to make it. Here is how they compare, and why our clinicians prescribe glutathione itself.
A once-weekly semaglutide injection goes under the skin of your stomach, thigh or upper arm, once a week on the same day. Here is how to inject semaglutide from a compounded vial the way FDA and NIH guidance describe it, with your dose always set by your clinician.
Growth hormone peptides are sold everywhere online, but only a few have human trials and fewer still can be prescribed. Here are five of the most searched, what the FDA has said about each, and why sermorelin is the one a clinician can prescribe for adults.
A liposomal supplement and a compounded injection put the same molecule into the body by very different roads. Here is what each has been shown to do, where the evidence stops, and how our clinicians weigh the two.
Harbor's tirzepatide arrives in a vial, not a pen, so each weekly dose is drawn into a syringe and injected under the skin. This guide walks through how to inject tirzepatide from a compounded vial, using the FDA-approved vial instructions for tirzepatide and NIH guidance as the reference points. Your clinician sets the dose and the units.
Both are molecules your cells make, both fall with age, and both are sold as at-home injections. They do different jobs. Here is what each one does, what the evidence can and cannot say, and how the two connect.
Both deliver the same molecule. Glutathione injections are a small dose at home on a schedule your clinician sets; an IV drip is a clinic appointment with a needle in a vein. Here is the honest comparison.
Both prompt your pituitary to release more of its own growth hormone. Only one is prescribed after a physician review and prepared by a licensed U.S. pharmacy. Here is the honest comparison, and how our clinicians weigh it.
Social media calls berberine "nature's Ozempic." It is a plant compound sold as a supplement, and it does not work like semaglutide. Here is what the evidence shows for weight and blood sugar.
One is an approved medication you can start this month. The other is a promising investigational drug still working through phase 3. Here is how they compare, and what the retatrutide headlines leave out.
