Pramlintide
Improving postprandial glucose control in insulin-treated diabetes
Pramlintide is particularly well-suited for individuals focused on improving postprandial glucose control in insulin-treated diabetes. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Reducing insulin dose requirements while maintaining glycemic control
Pramlintide is particularly well-suited for individuals focused on reducing insulin dose requirements while maintaining glycemic control. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Supporting weight management in insulin-treated T1DM and T2DM patients
Pramlintide is particularly well-suited for individuals focused on supporting weight management in insulin-treated t1dm and t2dm patients. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Addressing amylin deficiency in insulin-dependent diabetes
Pramlintide is particularly well-suited for individuals focused on addressing amylin deficiency in insulin-dependent diabetes. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.
Tirzepatide
People Who Want Maximum Weight Loss Results
If you're serious about losing significant weight, tirzepatide delivers results that were previously only achievable through bariatric surgery. Clinical trials showed average weight loss exceeding 20% of body weight—that's 50+ pounds for someone starting at 250 pounds. No other medication comes close.
Those Who Haven't Succeeded with Semaglutide
Thanks to its dual GIP/GLP-1 mechanism, tirzepatide often works better for people who had limited results with GLP-1-only drugs like semaglutide. The added GIP activation provides extra metabolic benefits that can break through plateaus and deliver superior weight loss.
People with Type 2 Diabetes Needing Aggressive Control
Head-to-head trials proved tirzepatide beats semaglutide for blood sugar control. The average HbA1c reduction of over 2 percentage points means many people can dramatically reduce or eliminate other diabetes medications. It's a genuine game-changer for metabolic health.
Individuals Looking to Transform Their Relationship with Food
Tirzepatide doesn't just reduce hunger—it fundamentally changes how food appeals to you. Users describe feeling free from constant food thoughts, finding it easy to stop eating when satisfied, and losing interest in formerly irresistible treats. It's not willpower—it's biochemistry working for you.

& evidence
Pramlintide
Evidence Level
Strong human trials (Phase 3 or FDA approved)
FDA Status
FDA approved for this use
Safety Overview
FDA-approved pramlintide demonstrates good tolerability in insulin-treated diabetes with well-characterized safety profile from >20 years clinical use. Gastrointestinal side effects (nausea) occur in 30-50% of initiators but typically resolve within 1-3 weeks. Hypoglycemia risk, especially when combined with insulin, requires dose coordination and patient education. Pancreatic side effects theoretically possible but not documented in clinical trials. Pregnancy category C requires careful consideration.
Contraindications
- xConfirmed gastroparesis requiring treatment
- xHypoglycemia unawareness (inability to recognize hypoglycemic symptoms)
- xKnown hypersensitivity to pramlintide or metacresol
- xPediatric patients (safety not established in children)
Tirzepatide
Evidence Level
Strong human trials (Phase 3 or FDA approved)
FDA Status
FDA approved for this use
Safety Overview
Tirzepatide has been extensively studied in the SURPASS (diabetes) and SURMOUNT (obesity) trial programs, involving thousands of participants over multiple years. The FDA approved it after thorough safety review. While GI side effects are common (especially during dose increases), they're typically mild to moderate and improve over time. Serious adverse events are rare. The SURPASS-CVOT trial is ongoing to evaluate long-term cardiovascular outcomes.
Contraindications
- xPersonal or family history of medullary thyroid carcinoma (MTC)
- xMultiple Endocrine Neoplasia syndrome type 2 (MEN2)
- xHistory of serious allergic reaction to tirzepatide or any GLP-1/GIP medication
- xCurrent or recent pancreatitis
- xPregnancy or planning to become pregnant
