Tirzepatide
Compounded Subcutaneous Injectable — Dual-Receptor Weekly Protocol
Tirzepatide is the first dual GLP-1 and GIP receptor agonist clinically proven to produce greater weight loss than any single-receptor treatment. In the SURMOUNT-1 trial, participants lost up to 22.5% of body weight — results previously unseen in any pharmacological weight loss study. Our protocol starts at 2.5mg and titrates safely to your optimal dose.

Why dual-receptor matters
Most weight loss medications target one pathway. Tirzepatide targets two — and the difference is significant.
Signals the brain to reduce hunger, slows gastric emptying, and lowers food intake at the source.
Improves insulin sensitivity, enhances fat metabolism, and helps reset your body’s weight set point.
Together, GLP-1 + GIP produce greater fat loss than either pathway alone — backed by SURMOUNT trial data.
SURMOUNT-1 participants at 15mg lost an average of 52 lbs over 72 weeks. No other drug has matched this.

Quality Control
Every API tested 5 ways before it touches a vial.
The active pharmaceutical ingredients in your medication are tested at the API level — before compounding — across five independent quality markers.
Confirms you’re getting exactly the dose on the label. No underdosed vials.
Zero microbial contamination. Required for anything injected into the body.
Tests for bacterial byproducts that cause dangerous inflammatory responses.
Ensures the compound is stable and safe at the correct physiological pH.
Verifies there are no foreign substances, degradants, or unknown compounds present.
Real people. Real results.

“I tried semaglutide for four months and hit a plateau. Switched to tirzepatide and the difference was immediate. My appetite dropped to almost nothing in week two. I’m down 31 lbs total and finally feel like this is sustainable.”
“My doctor recommended tirzepatide because of my insulin resistance. Three months in and my A1C dropped, I’m down 24 lbs, and I have more energy than I’ve had in years. The dual mechanism is real — this is different from anything I’ve tried.”
“The intake process was fast and the provider actually read my history. I was approved for tirzepatide specifically because of my metabolic profile. Six months in, down 38 lbs. The HumanPeptide process is legitimately better than my local clinic.”
What to expect
Results are real — but they take time. Here’s a realistic timeline.
2.5mg starting dose. Body adjusts. Appetite begins to shift. Mild nausea possible and temporary.
Titrated to 5mg. Early losses of 5–8 lbs. GIP receptor activity improving insulin response.
Significant and visible fat loss. Cravings largely gone. Most members see 10–15 lbs lost.
SURMOUNT-1 data: up to 22.5% body weight reduction. Average participant lost over 50 lbs at 72 weeks.
Before you begin
A few things to know so you’re set up for success from day one.
Inject subcutaneously once weekly as directed by your provider. Rotate injection sites — abdomen, thigh, or upper arm — to minimize tissue irritation.
Store vials refrigerated (36–46°F). Do not freeze. Keep out of direct light. Reconstituted solution is stable for up to 28 days refrigerated.
Never mix with other medications in the same syringe. If you experience unexpected side effects, hold your current dose and contact your provider before continuing.
Eat smaller, more frequent meals during titration. Nausea is common early on and almost always resolves by week 4. High-fat meals may worsen GI symptoms at first.
Never self-escalate your dose. Titration is managed by your provider and timed specifically to minimize side effects while maximizing results.
Your starting dose and titration schedule are determined by your provider post-intake review. Individual protocols vary based on metabolic history and goals.

- → Are looking for the strongest clinically-validated option available
- → Are not pregnant or breastfeeding
- → Are in one of our currently served states
❌ Not recommended if you…
- → Have a personal or family history of medullary thyroid cancer or MEN2
- → Have a history of pancreatitis

I’ve been obese my entire adult life. Tried everything — keto, Ozempic, personal trainers. Tirzepatide through HumanPeptide changed my life. 52 lbs down in 7 months. My cardiologist reduced two of my medications. I wish I had done this years ago.
✓ Verified PurchaseWas on semaglutide for 3 months and lost about 12 lbs. Switched to tirzepatide and lost 11 lbs in my first month alone. The appetite suppression is on another level. The GIP component really does something different. Worth every dollar.
✓ Verified PurchaseFirst two weeks were uncomfortable — nausea after eating and low energy. But my provider told me exactly what to expect and it cleared up completely by week 3. Down 28 lbs in 4 months. Four stars because week one is genuinely hard — but worth it.
✓ Verified PurchaseWhat impressed me most was that the provider didn’t just rubber-stamp my intake. They asked a follow-up question about my A1C and actually tailored my starting dose. That’s real medicine. 20 lbs down in 10 weeks and my insulin sensitivity has improved significantly.

Straight answers. No fluff.
Semaglutide targets GLP-1 receptors only. Tirzepatide targets both GLP-1 and GIP receptors simultaneously — making it a dual agonist. In head-to-head comparisons, tirzepatide consistently produces greater weight loss. The SURMOUNT-1 trial showed up to 22.5% body weight reduction versus 15–17% for semaglutide in comparable studies. For patients with insulin resistance or metabolic syndrome, the GIP mechanism provides additional benefit beyond appetite suppression.
The standard starting dose is 2.5mg once weekly for the first 4 weeks. After that, your provider will titrate your dose upward based on your tolerance and progress — typically increasing to 5mg, 7.5mg, 10mg, 12.5mg, and eventually up to 15mg at monthly intervals. Not everyone reaches the maximum dose; your provider will find your optimal therapeutic level.
Tirzepatide is the active compound in both Mounjaro (approved for type 2 diabetes) and Zepbound (approved for obesity). Our version is compounded by an FDA-registered 503A pharmacy, which means it uses the same active ingredient but is not an FDA-approved brand-name drug. Compounded tirzepatide is legally dispensed under a valid prescription from a licensed provider.
Yes. Tirzepatide is a prescription medication. After completing your intake form, a licensed provider reviews your health profile. If approved, they issue your prescription and it’s filled by our compounding pharmacy. No office visit required.
We currently serve: Florida, Rhode Island, Missouri, Wisconsin, Montana, Arizona, Vermont, Virginia, Wyoming, South Dakota, New York, Georgia, and New Mexico. We’re expanding — check back if your state isn’t listed.
The most common side effects are nausea, diarrhea, and reduced appetite — typically most pronounced in the first 2–4 weeks of a new dose. These are manageable and almost always resolve as your body adjusts. Eating smaller, more frequent meals and avoiding high-fat foods during titration significantly reduces GI symptoms. Serious side effects are rare and screened for during your intake.
