Rooted in your biology.
Growing with your life.

Lennox was built around a single conviction: use this medication the right way, or don't use it at all. We're intentional about what we offer, how we dose it, and who we partner with. Lennox is designed for people who are serious about their health — those already committed to strength training and eating well, who want tirzepatide to be the missing piece that finally makes everything fall into place. This isn't a quick-fix clinic. It's a long-term health practice.

We start conservative, progress gradually, and keep long-term metabolic health as the north star. The goal isn't the fastest possible number on the scale — it's finding the dose where food noise fades, hunger becomes manageable, and your body finally starts cooperating with your goals.

Many clinics are financially motivated to push your dose higher. Higher doses mean higher monthly billing. Our philosophy is the opposite. If you can achieve your result on less, that is always the better path — fewer side effects, lower cost, and better outcomes over time.

We source exclusively from licensed U.S. 503A compounding pharmacies. Quality, safety, and regulatory compliance are not optional — they're the baseline.

We've worked to keep our pricing as competitive as possible. If you're serious about using this medication correctly, cost shouldn't be the thing that holds you back.

Lennox wasn't started by investors looking for the next health trend. It was founded by someone who watched this medication change the lives of people closest to him — including members of his own family — and experienced meaningful results himself. That personal journey shaped everything about how this clinic operates: the emphasis on doing it right, the focus on muscle preservation, and the belief that this tool deserves more respect than it typically gets.

Lennox serves 48 U.S. states. Whether we can serve your state depends on provider licensing and the pharmacy that fills your prescription — we confirm your eligibility during the online intake, before any provider prescribes.

Everything is online — there's no in-person visit. You complete a short medical intake about your history and goals, a licensed provider reviews it, and if tirzepatide is appropriate they write your prescription. Most reviews are completed the same day.

Your consultation and prescription are handled by independent, U.S.-licensed clinicians through LocumTele, our provider network. Lennox is the platform that coordinates your care; the clinical decisions belong to your provider.

Every prescription is prepared and dispensed by Rush Pharmacy, a licensed U.S. compounding pharmacy. Lennox does not own or operate a pharmacy.

You can cancel future charges anytime before your next billing date from your account, or by contacting our care team at care@lennox.health or (855) 610-4487. Because each vial is compounded specifically for you, medication that's already been dispensed generally can't be refunded — the full details are in our Shipping & Refund Policy.

Tirzepatide is a dual-action peptide — a chain of amino acids — that targets two key metabolic pathways simultaneously. It activates GLP-1 receptors, which slow digestion and communicate a sense of fullness to the brain, dialing down the constant pull toward food. It also activates GIP receptors, which sharpen insulin sensitivity, support glucose clearance, reduce glycation, and improve how muscles utilize glucose. This two-pronged mechanism makes tirzepatide one of the most powerful metabolic tools currently available.

Most GLP-1 medications work through a single receptor pathway. Tirzepatide's combined GIP and GLP-1 activity produces a stronger, more comprehensive effect on both appetite regulation and metabolic function.

Retatrutide is a triple agonist that shows slightly greater total weight loss in clinical trials. However, current data suggests tirzepatide tends to produce more favorable body composition outcomes — meaning better fat loss relative to preserved lean mass. Retatrutide has also been linked to a more notable rise in resting heart rate and may disrupt sleep in some users. For members focused on body composition, metabolic health, and overall tolerability, tirzepatide is what we recommend and prescribe based on the evidence available today.

We offer two tirzepatide microdose blends. The B12 + NAD Blend supports sustained energy through B12, with NAD providing an additional layer of mental clarity and cognitive performance. The L-Carnitine Blend supports fat mobilization and mitochondrial energy production, offering mild complementary fat loss support.

The amount varies slightly based on state regulations. Most members receive 10 mg per month; certain states permit up to 17 mg, while others cap it at 8.5 mg. Every dose is calibrated to be clinically effective while keeping side effects to a minimum.

We recommend beginning at 1.25 mg per week. This gives your body time to acclimate without rushing the process. It's a deliberate starting point — the idea is to observe how you respond before gradually increasing. Most members work up to 2 mg or 2.5 mg weekly over time, depending on their goals and tolerance.

Results depend on your starting point, nutrition, and consistency — but the underlying mechanism is straightforward. As long as you're in a calorie deficit, your body will continue losing fat. Tirzepatide makes that deficit easier to sustain by reducing appetite and improving how your body handles the food you eat. If progress stalls, it's almost always because appetite has gradually returned enough to close the deficit. A modest dose adjustment typically restores appetite suppression and gets things moving again. The medication doesn't stop working — the goal is finding the dose that keeps you comfortably in a deficit. Combined with solid nutrition, consistent training, and daily movement, reaching your ideal body composition is very achievable.

No. Tirzepatide has no direct effect on muscle, bone, or hair. The receptors it targets are not involved in muscle metabolism. Muscle loss is only a risk if you severely under-eat and neglect protein intake. With adequate protein, sufficient calories, and consistent resistance training, you can lose body fat while preserving — or even building — muscle. Tirzepatide supports that process by improving satiety and insulin sensitivity.

Absolutely. The GIP mechanism improves insulin sensitivity, supports glucose clearance, and reduces glycation regardless of your starting body composition. For people already at a healthy body fat level, low-dose tirzepatide functions as a powerful metabolic optimization tool — not just a fat loss aid. Many of our members use it to stay effortlessly lean, improve how their body partitions energy, and support long-term metabolic health.

There's no meaningful evidence of tolerance or declining efficacy with continued use. What some people notice is that appetite gradually increases as they get leaner — but this isn't the medication losing effectiveness. It's a natural physiological response: as body fat drops, leptin levels decrease and hunger signals increase. A small dose adjustment is usually all it takes to get back on track.

The focus shifts to maintenance. We recommend staying on a low maintenance dose to make it easy to hold your new set point without constant effort. If you were at 2 to 2.5 mg weekly during active fat loss, you can often step down to 1.5 to 2 mg. The goal is identifying the minimum effective dose that keeps appetite in check at your target weight.

Over the following few weeks, appetite will gradually return to your natural baseline. This is completely normal. If you continue eating at maintenance calories, you won't gain body fat — weight comes back only if you return to the habits that created excess body fat in the first place. Many members find that their time on tirzepatide helps them recalibrate their relationship with hunger and food, making it significantly easier to maintain results long after stopping.

The most commonly reported side effects are gastrointestinal — mild nausea or digestive sensitivity. Importantly, these are associated with higher doses and aggressive escalation, not the microdosing range. By starting at 1.25 mg and building slowly, the vast majority of our members experience little to no side effects. Keeping doses conservative isn't a compromise — it's a core part of the Lennox approach.

Yes. Tirzepatide is a prescription medication. Lennox's telehealth physicians handle the consultation and prescription process entirely online — no in-person visit required.

Most members use a once-weekly subcutaneous injection with a small insulin needle — hair-thin, just beneath the surface of the skin. Your kit includes everything you need: medication, alcohol swabs, needles, and clear step-by-step instructions. Prefer not to inject? We also offer tirzepatide as a daily sublingual that dissolves under your tongue — no needles at all.

Both deliver compounded tirzepatide prescribed by a licensed U.S. provider. The injection is a once-weekly shot you give yourself with a hair-thin needle. The oral is a daily sublingual that dissolves under your tongue, with no needles. Which one fits you best comes down to your preferences and your provider's guidance — you can talk it through during your consultation. Both are offered at the same flat monthly price.

Once your order is placed, a physician reviews it the same day. Most U.S. members receive their kit within three business days.
