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?

Compounded medications are not FDA-approved. Our compounding pharmacy operates as a 503A/503B facility, which means it is subject to some FDA oversight under the FD&C Act and follows USP 797 & 795 standards. Compounded GLP-1 medications are prepared by a licensed pharmacist under a valid prescription for an individual patient and are not 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 proven single GLP-1 agonist — excellent for most patients starting their weight loss journey. Tirzepatide adds a GIP receptor component for a stronger dual-agonist effect and greater weight loss potential. Retatrutide is our most advanced option — a triple agonist (GLP-1, GIP, and glucagon) with the highest clinical weight loss outcomes observed.

Can I cancel my plan anytime?

Monthly plans can be cancelled at any time with no penalty. Quarterly plans are prepaid for the 3-month period, but we offer a satisfaction guarantee — please contact our care team if you have concerns and we will work with you personally.

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.
