Semaglutide Injection
A GLP-1 receptor agonist that works with your body's appetite and blood-sugar signaling to support weight management.
- Appetite signaling — less mental noise around food
- Weight management alongside nutrition and strength work
- Steadier blood-sugar signaling

How it works, and what that feels like
Semaglutide has the longest clinical track record of the GLP-1 medications, which is the main reason it is where most people start.
It is also the one most surrounded by noise — miracle framing on one side, dismissal on the other. What follows is neither: what it does, what it actually feels like, who it suits, and what happens when you stop.
Semaglutide is a GLP-1 receptor agonist. GLP-1 is a hormone your gut already releases after eating; it signals fullness to the brain, slows how quickly the stomach empties, and helps regulate the insulin response to a meal. The medication works with that existing system rather than overriding it. If you are curious about the biology, GLP-1s are peptides covers it.
The subjective experience is worth describing, because it is not what most people expect.
It is not willpower arriving. It is more that the background noise quietens. The mental loop that returns to food several times an hour tends to fade, and meals finish sooner because you are full sooner. People often describe it as food occupying less space in their head — which is a different thing from wanting food and resisting it.
That distinction matters for two reasons. If you were expecting a stimulant-like effect, this will not feel like that. And if you have spent years being told your weight was a discipline problem, discovering that the difficulty was partly biological is a genuinely significant reframe. Many people find that the more useful part.
Semaglutide is a GLP-1 receptor agonist. It works with the body's own appetite and blood-sugar signaling as part of a structured, clinician-monitored plan. The semaglutide prescribed through ACT 2 Health is prepared by a licensed compounding pharmacy. It is not an FDA-approved product, and it is not the same as, equivalent to, or interchangeable with any branded medication.

Injection, capsule, or your own insurance?
The molecule is the same; the delivery and the economics differ.

The honest summary: if your insurance covers a branded GLP-1, check that first. The membership lets you obtain the branded medication through your own benefit and pay us only for the clinical care around it — frequently the better structure, and we would rather tell you that than sell you something you could get covered.
Choosing between semaglutide and tirzepatide is a separate question, and a clinical one. Neither is better as a general matter, and we do not publish comparative outcome figures for compounded medications.
The part almost nobody covers: GLP-1s and menopause
If you are a woman in your forties or fifties who feels like her body changed the rules, this section is the reason this page exists.
Weight change through perimenopause and menopause is not the same problem as weight change at thirty. Falling estrogen shifts where the body stores fat — typically toward the abdomen — and it happens alongside declining muscle mass, disrupted sleep and, often, a metabolic picture that has quietly moved. The strategy that worked before frequently stops working, and it is not because you stopped trying.
Two things follow from that.
A GLP-1 can help, and it is not the whole answer. It addresses appetite and metabolic signaling. It does not address the hormonal shift underneath, and treating one while ignoring the other is a common route to a disappointing result.
These conversations belong together. Hormone therapy and medical weight management are usually discussed at different clinics by different people, which is why so few women get a plan that accounts for both. Ours are the same conversation. If weight is your reason for coming to us and you are in the transition, expect to be asked about sleep, hot flashes and cycle changes too — not as a digression, but because they are part of the same picture. See menopause and perimenopause care.
Who it is for — and the cutoff we do not use
Semaglutide is considered for adults in midlife carrying weight that resists lifestyle change.
There is no blanket BMI cutoff. Eligibility is assessed case by case, on your symptoms, your metabolic picture and your history. A single threshold captures none of what actually drives midlife weight change, which is why we measure first — thyroid function, insulin, and hormones frequently explain more than the scale does.
What to expect, and what to watch for
Side effects are mostly gastrointestinal, nausea most commonly, and often ease with careful adjustment by your clinician over time. Telling us early matters — most of the time the plan can be modified rather than abandoned.
Contact your clinician promptly for: severe or persistent abdominal pain, which can indicate pancreatitis or a gallbladder problem; persistent vomiting or signs of dehydration; or a lump or swelling in the neck, difficulty swallowing, or persistent hoarseness.
Not appropriate if you have a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2; if you are pregnant, breastfeeding or trying to conceive; or with a history of pancreatitis without careful evaluation.
Because these medications slow stomach emptying, they can change how other things you take are absorbed — including oral contraceptives. Bring your full medication list.
What happens if you stop
These medications work while you are taking them. Appetite regulation generally returns toward its previous state afterwards, and for many people weight follows. That is the mechanism, not a personal failure.
What carries forward is what you built along the way — the eating patterns, the training habit, the sleep, and the muscle you protected. Which is the honest case for treating this as a program with a plan for afterwards.
Not necessarily forever, either. Your protocol is reviewed and adjusted over time, and some members taper as habits and biomarkers improve.
Delivery
A once-weekly subcutaneous injection, with your regimen guided by your clinician over time.
Is it right for you?
Adults 45+ carrying weight that has not responded to lifestyle change, who want the option with the longest track record — and monitoring rather than a monthly delivery. See medical weight loss for how the program is run.
Other ways to do this
If needles are the obstacle, oral capsules are the same molecule. If a dual-pathway approach fits your metabolic picture, tirzepatide. And if your insurance already covers a branded GLP-1, look at the membership before anything else — the price shown here is an ongoing monthly cost plus periodic labs, not a one-off.
If you are in perimenopause or menopause, read hormone therapy for women alongside this. For many women that is the conversation that changes the outcome. More on how we approach it in women's health.

An honest word on the track record
Semaglutide has the longest clinical record of the GLP-1 medications, and that is a real advantage — but it is a record built with the FDA-approved branded product, not with a compounded preparation, so those figures do not carry across and this page quotes none of them. What we can tell you is this: semaglutide is prescribed only for eligible patients under clinical evaluation and ongoing monitoring, side effects are mostly gastrointestinal and often ease over time, and individual response varies.

Frequently asked questions
It works with your body's appetite and blood-sugar signaling, alongside nutrition and strength work, as part of a monitored plan. GLP-1 is a hormone your gut already releases after eating; the medication engages that existing system. Individual response varies.
Most people describe the mental loop around food quietening rather than a surge of willpower, and meals finishing sooner because fullness arrives sooner. It is not stimulant-like. If you were expecting that, this will feel different.
No. There is no blanket BMI cutoff. Eligibility is assessed case by case on your symptoms, metabolic picture and history.
Frequently, yes — and for many women in the transition it is the more complete approach. Weight change in perimenopause is entangled with hormonal change, and addressing only one often disappoints. Both are reviewed together as part of your plan.
Some muscle loss can occur with any significant weight loss. Our protocols emphasize protein, resistance training and ongoing monitoring to support lean mass. Individual results vary.
Then look at the Weight Loss Program Membership. You obtain the branded medication through your own pharmacy benefit and pay us only for the clinical care around it — often the better structure.
