Weight Loss Support with GLP-1 Injections

Why GLP-1 at Spa 35

Weight loss that works — backed by science, guided by your labs

At Spa 35, we've been helping Boise feel confident since 2006. Our GLP-1 weight loss program is built on individualized care — not a one-size-fits-all approach. Every patient begins with blood work and laboratory analysis so your Nurse Practitioner can calibrate your treatment plan precisely to your body's needs.

GLP-1 peptides are an injectable class of medication that mimics a natural gut hormone. They slow gastric emptying and reduce glucose absorption, increasing insulin production and triggering a hormone that keeps food in your stomach longer — decreasing your appetite and making you feel fuller faster.

As you progress through our three-phase program, dosing is adjusted to optimize results while minimizing side effects. Your body fat percentage may be a better measure of your progress than total body weight alone.

FAQ

Weight loss treatment FAQs

Your questions, answered honestly.

How do GLP-1 Peptides work?

GLP-1 peptides regulate the production of insulin and your speed of digestion. They slow gastric emptying, increase insulin production, and trigger a hormone that keeps food in your stomach longer. You feel fuller faster and your appetite is decreased.

What is the process?

GLP-1 injections are delivered weekly at Spa 35. You'll start by completing a comprehensive questionnaire about your medical history. At your first appointment you'll meet with a Nurse Practitioner who will review your current condition of health to ensure you're a good candidate. If you are healthy and have an appropriate body mass index you'll get your first injection. Then each week you'll come in for a very quick injection from a registered nurse. It is important to stay on a very repetitive weekly schedule. If you miss a weekly appointment your dosage may be decreased to minimize side effects.

Do I need to change my diet?

Yes. You'll be eating less, so it is important to eat foods with high nutritional content and plenty of protein. A potential effect of GLP-1 therapy is the loss of muscle mass, which you want to minimize with exercise and diet.

How much weight will I lose?

Your weight loss depends upon a variety of individual factors including your starting point, diet, exercise habits, and how your body responds to treatment. Results vary from person to person. GLP-1 injections decrease your appetite but do not speed up your metabolism. Your body fat percentage may be a better measure of GLP-1 effectiveness than your total weight. We encourage pairing treatment with a high-protein diet and regular physical activity to support your goals.

How long before I see results?

Results vary and the timeline depends on your individual response to treatment, your diet, and your activity level. Consistency is key — staying on your weekly injection schedule and working with your provider to adjust dosing as needed gives you the best chance of achieving and maintaining your goals. Body fat percentage may be a better measure of your progress than the scale alone.

What are the potential side effects?

Common side effects include nausea, constipation, diarrhea, fatigue, and loss of facial fullness. Eating smaller meals, avoiding high fat foods, and remaining upright after eating can decrease nausea. GLP-1 peptide injections may cause serious side effects including thyroid C-cell tumors and pancreatitis. You should not get injections if you have a personal or family history of these conditions. See the Informed Consent form for a complete list of risks and potential complications.

What is "GLP-1 Face"?

Some patients undergoing GLP-1 therapy experience a loss of facial volume as a result of rapid weight loss — a phenomenon sometimes referred to as "GLP-1 Face." Limiting the speed of your weight loss and eating a high-quality diet with plenty of protein may decrease this risk. Spa 35 offers dermal filler treatments that can address volume loss in the face.

What happens when I stop treatment?

You may regain weight when stopping GLP-1 injections. It is important to adopt healthy diet and exercise habits while you are using GLP-1 therapy so you can maintain your progress when you stop treatment. We encourage you to discuss any concerns with your provider — adjusting your dose or schedule is often a better solution than stopping treatment entirely.

Are GLP-1 Peptides FDA approved?

As a compounded formulation, the GLP-1 medication offered at Spa 35 is considered "off-label" and has not been independently reviewed by the FDA for weight loss. Some proprietary GLP-1 formulations have received FDA review and approval. If you have a BMI greater than 27 and other weight-related medical conditions, you may be eligible for one of these FDA-reviewed medications — ask your provider about your options.

What if I need to cancel my membership early?

If you choose to end your six-month membership agreement before completion, an early termination fee of $500 applies. We encourage you to discuss any concerns with your provider before stopping treatment.

Weight loss secret of the stars!

Since 2006 Spa 35 has been helping people look and feel their best!

GLP-1 Peptides are an injectable medication of a glucagon-like peptide (GLP-1) antagonist that slows gastric emptying and reduces glucose absorption. This increases your insulin production and triggers a hormone that keeps food in your stomach longer. This decreases your appetite makes you feel fuller quicker and longer. So, you eat fewer calories, resulting in weight loss.

What is the process?

GLP-1s are delivered in weekly injections at Spa 35. You’ll start by completing a comprehensive questionnaire about your medical history. At your first appointment you’ll meet with a Nurse Practitioner who will review your current condition of health to ensure you’re a good candidate for GLP-1 injections. If you are healthy and have an appropriate body mass index you’ll get your first injection with the Nurse Practitioner. Then each week you’ll come in for a very quick injection from a registered nurse. It is important to stay on a very repetitive weekly schedule. If you miss a weekly appointment your dosage may be decreased to minimize side effects. Your experience with side effects will be monitored and dosage will be increased based upon your response to Semaglutide weight loss injections.

How much weight will I lose?

Your weight loss depends upon a variety of factors. Some studies have shown up to ten percent of weight loss in twelve months. You can maximize your weight loss by adopting a robust diet and exercise program. GLP-1 injections decrease your appetite, but it does not speed up your metabolism. Your body fat percentage may be a better measure of GLP-1 effectiveness than your total weight.

Some potential side effects include

Constipation
Diarrhea
Fatigue
Loss of facial fullness (a.k.a. Ozempic face)

The most common side effects are nausea and constipation. Eating smaller meals, avoiding high fat foods, and remaining upright after eating can decrease these side effects. Over the counter medications can be used for these side effects. Some people report not feeling as thirsty as before starting treatment, which may contribute to constipation. Increasing water intake may decrease your risks of constipation. See the Informed Consent form for a complete list of risks and potential complications.

GLP-1 Peptide injections for weight loss at Spa 35 are intended for healthy individuals. If you suffer from chronic disease or any contraindications, you should not start injections before consulting your primary care provider. Come to Spa 35 ready to have your weight measured and clothing that allows your provider to access your abdominal area.

GLP-1 injections are performed with a very small needle, and you should experience mild or no discomfort. You may experience small pinpoint bleeding and/or minor bruising.

We recommend that you eat before your treatment because you may feel uncomfortable during meals after your injection.

GLP-1 peptide injections my cause serious side effects including thyroid C-cell tumors and pancreatitis. You shouldn’t get injections if you have a personal or family history of thyroid tumors or pancreatitis.

Spa 35 is offering a compounded version of Semaglutide that is not Ozempic® or Wegovy®. Ozempic® and Wegovy® are registered trademarks of Novo Nordisk A/S. If you have a BMI of greater than 27 and other weight related medical conditions you may be eligible for Wegovy.

Check with your medical provider for additional information. Spa 35 GLP-1 Peptide injections are considered “Off-label” because the compounded version of Semaglutide has not been reviewed by the FDA for weight loss.

Encouraging Weight Loss Success

I would strongly encourage ANYONE dealing with issues concerning hormones, and the struggle to take off weight, even getting aligned with the body's internal thermostat, see Missy and get the consult on hormone replacement therapy! LIFE changer! Hormones, healthy weight loss, and overall health are Missy's passions...something she's been studying and understanding for a long time. Your hormones may be the reasons for low energy, insomnia, weakness, and keeping the weight on. I would never even have thought of my hormones being the culprit until Missy mentioned it and got me on the path to better overall health! Spa 35 isn't JUST a medical spa for beauty and skin care, it's comprehensive and pinpoints the WHY to the WHAT and WHEN regarding my skin, my weight, and hormones. GAME changer, HRT. Missy's the professional I was hoping to come across, and I take her work and word as gospel! Best thing I ever did!

I am so happy to hear that Spa 35 will now be offering hormone replacement therapy! I already feel so comfortable with Missy and I know I will be in the best hands! Past review: I had heard all about losing weight on semaglutide but I was hesitant to start a new medication. I was happy to hear that my consultation would be with a nurse practitioner who could answer all the questions I had. Missy went above and beyond during our consultation; she answered all of my questions thoroughly, was very friendly and was non-judgmental. I stayed on the medication for two months and accomplished my goal weight loss. I am very satisfied with my overall experience at Spa35.
