Sound Familiar?

If Any of These Sound Like You...

You're exactly who Thinnex was built for. The weight has nothing to do with willpower — and everything to do with biology.

You've been told to "just eat less" — but hunger always wins

That's not weakness. That's hormones. GLP-1 therapy addresses hunger at its biological source.

You feel like your metabolism changed after 35

It did. Hormonal shifts, declining NAD+, and metabolic slowdown are real — and treatable with the right protocol.

Ozempic is backordered — and your insurance won't cover it

Compounded GLP-1s through Thinnex are available now, at a fraction of the brand-name cost. No insurance required.

You don't have time for weekly clinic visits

100% telehealth. Your intake takes under 10 minutes. A real doctor reviews it. Your Rx ships to your door.

You want real medical supervision — not a cookie-cutter app

Every Thinnex patient is reviewed by a board-certified physician. Your protocol is built for your biology, not a template.

GLP-3

Compounded Triple Agonist

GLP-1 · GIP · Glucagon

GLP-3 is a triple-receptor agonist that acts on the GLP-1, GIP, and glucagon receptors — pathways involved in appetite regulation, blood-sugar control, and energy metabolism. In a Phase 2 randomized, placebo-controlled clinical trial published in the New England Journal of Medicine (Jastreboff et al., 2023), participants receiving the highest dose of a triple GLP-1/GIP/glucagon receptor agonist achieved a mean body weight reduction of 24.2% at 48 weeks. This trial was conducted on pharmaceutical-grade Retatrutide and was not performed on this compounded product. Individual results will vary.

Important Disclosure Compounded GLP-3 is not FDA-approved and has not been approved by the FDA for any indication. It is an investigational compound available through a licensed compounding pharmacy under a valid prescription from a board-certified provider. It has not been evaluated by the FDA for safety, efficacy, or quality in this compounded form. Individual results vary — no specific outcome is guaranteed. Consult your primary care provider before starting any new medication.

Body Composition

Tesamorelin

Growth Hormone-Releasing Factor

GH Release · Fat Loss · Muscle

Tesamorelin is a growth hormone-releasing factor (GHRF) analogue that stimulates your pituitary to produce natural growth hormone. It acts on the body's growth hormone pathway to support changes in body composition under physician supervision.

Important Disclosure Tesamorelin (Egrifta) is an FDA-approved drug indicated for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. This compounded version of Tesamorelin is not the FDA-approved product and has not been evaluated by the FDA for safety, efficacy, or quality. It is prepared by a licensed compounding pharmacy under a valid prescription from a board-certified provider. Use outside the approved indication is off-label. Individual results vary — no specific outcome is guaranteed. Consult your primary care provider before starting any new medication.

The Science

Why These Peptides Work

Our treatments are grounded in decades of peer-reviewed metabolic research, targeting the biological systems that govern hunger, satiety, and energy balance.

01

Appetite Regulation at the Source

GLP-1 receptor agonists directly interact with the hypothalamus — the brain's hunger control center — reducing appetite signals and caloric intake without willpower battles.

02

Improved Insulin Sensitivity

By stimulating incretin hormones, these peptides enhance glucose-dependent insulin secretion, reducing insulin resistance and lowering the risk of metabolic disease.

03

Cellular Energy with NAD+

NAD+ fuels the mitochondrial machinery that powers every cell. Restoring optimal NAD+ levels amplifies energy, sharpens cognition, and accelerates the metabolic benefits of GLP-1 therapy.

Common Questions

Everything You Need to Know

We believe in complete transparency. Here are the most common questions from people starting their journey.

Are these medications FDA-approved?

Our compounding pharmacy operates as a 503A facility, meaning it compounds medications for individual patients under a valid prescription from a licensed practitioner. 503A pharmacies are subject to oversight by state boards of pharmacy and some provisions of the FD&C Act. Compounded medications are not FDA-approved and have not been evaluated by the FDA for safety, efficacy, or quality.

How quickly will I receive my medication?

Most patients complete their telehealth consultation and receive their prescription within 24–48 hours of intake. Medication is then shipped from our compounding pharmacy and typically arrives within 3–5 business days. We offer overnight shipping options upon request.

Do I need insurance?

No insurance required — ever. All of our pricing is flat-rate and fully transparent. Your monthly or quarterly price covers everything: the medication, provider consultation, ongoing support, and free shipping. No surprise bills, no deductibles.

What's the difference between the GLP-1 options?

Semaglutide is a single GLP-1 agonist — a common starting point for many patients. Tirzepatide is a dual agonist that adds a GIP receptor component. GLP-3 is a triple-receptor agonist that acts on the GLP-1, GIP, and glucagon receptors. A board-certified provider will determine which option, if any, is appropriate for you.

Can I cancel my plan anytime?

Our programs are structured as 90-day plans, available with a pay-monthly or pay-upfront option. Here's why: one month of GLP-1 or peptide therapy isn't enough time to see meaningful results — your body needs at least 90 days to respond to the medication, dial in your dose, and build momentum. Stopping after a month is like leaving the gym after one workout. That said, if you have concerns at any point, contact our care team and we will work with you personally.

Does my medication price go up as my dose increases?

No — never. This is one of the biggest advantages of Thinnex over traditional weight loss clinics. Your flat monthly or quarterly rate stays the same regardless of your dose. Most GLP-1 programs start low and titrate up over time — with other providers that often means your price goes up too. With us, your price is locked in from day one. What you pay on month one is exactly what you pay on month three, even as your dose increases.

What does the NAD+ add to my treatment?

NAD+ is a critical coenzyme for mitochondrial energy production, DNA repair, and sirtuin activation. Many patients notice dramatically improved energy levels, mental clarity, and reduced fatigue. When combined with GLP-1 therapy, NAD+ can amplify metabolic results by improving cellular energy utilization alongside appetite regulation.

Am I a good candidate?

Our treatments are appropriate for adults with a BMI ≥ 27 (overweight) or ≥ 30 (obese), or those with weight-related health conditions. A board-certified provider will review your full health history and determine the safest and most effective treatment for your individual situation during your telehealth consultation.

Is there ongoing medical supervision?

Yes — absolutely. Your subscription includes ongoing access to your care team for dosing questions, side effect management, and progress monitoring. We are not a one-and-done Rx service; we are your long-term metabolic health partner.
