Your Clinician

Weight loss without bloodwork
is guesswork.

Crystal runs comprehensive metabolic bloodwork before prescribing any GLP-1 medication. She identifies insulin resistance, thyroid dysfunction, and hormonal imbalances that affect your ability to lose weight.

She monitors your progress, adjusts your protocol, and makes sure the medication is working with your body safely. Same clinician, every visit, every titration.

Your body is not broken. It is under-supported. Fix the foundation, and everything else follows.

The Difference

The white glove
experience.

A clinician-led, coordinated white glove premium clinical experience with 24/7 AI concierge support so you never have a disruption in treatment, never miss an appointment, and always feel supported.

White Glove Onboarding

From the moment you enroll, Brett personally walks you through onboarding, intake forms, scheduling, and everything you need to get started. You don't have to figure anything out.

White Glove Clinical Care

Crystal sees you personally at every appointment. Same clinician, every visit. No handoffs. No rotating providers. Your protocol is built for YOUR body, reviewed at every visit, and adjusted based on how you actually feel.

White Glove Coordination

Appointments scheduled in advance. Prescription refills coordinated before you run out. Bloodwork requisitions sent to your email. Lab locations looked up for you. The administrative work is handled so you can focus on feeling your best.

White Glove Follow-Through

After every appointment: check-ins. After every bloodwork: a clear protocol update. After every change: someone confirming it's working. This is how optimization is supposed to work.

The Problem

Tried everything
and still stuck?

You have restricted calories. You have exercised consistently. You have tried keto, intermittent fasting, meal plans, and commercial programs. And every time — you lose some weight, feel good for a few months, and watch it come back. Often more than you lost.

This is not a willpower failure. This is biology.

When you lose weight through calorie restriction alone, your body fights back — lowering your metabolic rate, increasing hunger hormones (ghrelin), and prioritizing fat storage. Your brain is literally working against your goals.

GLP-1 medications change the equation.

They work at the neurological and hormonal level — reducing appetite signals in the brain, slowing gastric emptying so you feel satisfied longer, and improving your body's insulin sensitivity.

For the first time, the biology works with you instead of against you.

Patient Experience

I got my body, my confidence, and my relationship back.

For as long as she could remember, Jennifer's relationship with food was a battle. Not because she lacked discipline — she had more discipline than anyone she knew. She had done Weight Watchers, keto, intermittent fasting, macro counting, juice cleanses, and two rounds of a commercial meal delivery program. She worked out four to five days a week. She drank her water. She did everything right. She avoided mirrors and dreaded getting dressed in the morning. Her relationship was suffering too — she had zero desire for intimacy, and the disconnect between her and her partner was growing wider every month.

I was so tired of hating my body. I was doing everything the internet told me to do and it wasn't working. I didn't want my partner to see me, let alone touch me. I started to think something was fundamentally wrong with me.

And every single time — she would lose fifteen pounds, feel amazing for two months, and then watch it come back. Usually more than she lost. By the time she found Tier1 Optimal, she had gained and lost the same thirty pounds three times in five years.

A friend told her about Crystal and GLP-1 medications. Jennifer was skeptical — she had heard of Ozempic but assumed it was only for diabetes or that it was some kind of shortcut. Her first conversation with Crystal changed that.

“Crystal explained that my body was literally working against me — that when I restricted calories, my hunger hormones surged and my metabolism slowed down to compensate. It wasn't willpower. It was biology. No one had ever explained that to me before.”

Crystal ran comprehensive bloodwork — not just the basics. Fasting insulin, thyroid, cortisol, metabolic markers, hormones — the full picture. She identified insulin resistance that had never been caught by Jennifer's family doctor.

By her 90-day check-in, the changes were undeniable. Jennifer had dropped several dress sizes. Clothes she had not worn in three years fit again. Her blood pressure had improved. Her energy was back. She was sleeping through the night. But what surprised her most was something she had not expected from a weight loss medication.

My confidence came back — and with it, my desire for my partner came back. I didn't realize how much the weight and the shame had killed that part of me. I actually feel attractive again. I want to be close to him again. That alone would have been worth it.

Crystal explained that the hormonal improvements from weight loss — reduced insulin resistance, improved metabolic function, and the psychological shift from feeling good in your own body — often restore libido that had been suppressed for years. It was not a separate problem. It was all connected.

The food noise just… stopped. For the first time in my entire life, I could just not think about food every second of the day.

This is an individual patient experience. Results vary. All treatment is subject to clinical assessment and medical eligibility. Tier1 Optimal does not guarantee specific outcomes.

Treatment Options

Four clinical
pathways.

Crystal matches the medication to your biology — not the other way around.

Option 01

Ozempic (Semaglutide)

Weekly injection

Health Canada-approved for type 2 diabetes and widely prescribed for weight management across Canada. Clinical trials showed approximately 15% average body weight loss. Crystal starts you on a low dose and titrates upward over several weeks to minimize side effects.

Option 02

Wegovy (Semaglutide)

Weekly injection · Higher max dose

Same active ingredient as Ozempic, specifically Health Canada-approved for chronic weight management at a higher maximum dose (2.4mg vs 1.0mg). Wegovy's clinical trials showed approximately 15–17% average body weight loss sustained over 68 weeks.

Option 03

Mounjaro (Tirzepatide)

Weekly injection · Dual-agonist

A dual GIP/GLP-1 receptor agonist — meaning it targets two hormonal pathways instead of one. Clinical trials showed potentially greater weight loss than semaglutide alone, with some studies reporting 20–25% average body weight loss.

Option 04

Contrave (Naltrexone/Bupropion)

Daily oral tablet

A non-injectable option that works on the brain's reward and craving pathways. Particularly effective for patients whose weight is driven by emotional eating, stress eating, or food cravings rather than purely appetite volume.

What to Expect

Your first
90 days.

  1. 01

    Week 1–2

    Food noise quiets.

    Appetite begins to reduce. The constant mental chatter about what to eat next starts to fade. Some mild GI adjustment (nausea, bloating) is normal as your body adapts.

  2. 02

    Week 3–6

    Weight loss measurable.

    Weight loss becomes measurable. Energy improving. You feel satisfied after normal-sized meals. The cravings that used to drive late-night eating start fading.

  3. 03

    Week 6–12

    Metabolic markers shift.

    Significant progress visible. Blood sugar, blood pressure, and cholesterol often improving. Clothes fitting differently. Energy and mood noticeably better. Crystal adjusts your dose through the titration schedule.

  4. 04

    90-Day Mark

    Crystal reviews & adjusts.

    Crystal reviews your full metabolic panel, assesses your progress, and adjusts your protocol. Issues your next 90-day prescription. Supply ships.

Insurance Note: Coverage for GLP-1 medications (Ozempic, Wegovy, Mounjaro) varies significantly between plans. Many insurers now require prior authorization or a Type 2 diabetes diagnosis for coverage. Brett can help you navigate your plan's specific requirements.

★ The White Glove Difference

Weight Loss protocols require coordination — lab timing, dosing adjustments, pharmacy follow-through, insurance navigation. We handle all of it. You just focus on your results.
