Peptide Stacking Guide
Evidence-based protocols for combining peptides safely and effectively. Each stack includes low-dose GLP-1 options for their powerful anti-inflammatory and metabolic optimization benefits — not for weight loss, but for optimizing how your body heals, recovers, and functions.
Why Every Stack Includes Low-Dose GLP-1
Tirzepatide and Retatrutide at low doses provide benefits that extend far beyond weight management. Here's why they're foundational to modern peptide protocols.
Anti-Inflammatory
Reduces CRP, IL-6, and TNF-alpha — the inflammatory cytokines that impair healing, sleep, cognition, and immune function.
Insulin Sensitivity
Optimizes how your cells respond to insulin, improving nutrient delivery to muscles and reducing fat storage.
Digestive Optimization
Slows gastric emptying for better nutrient extraction, improves gut motility, and supports intestinal barrier function.
Blood Sugar Stability
Prevents the glucose spikes and crashes that cause energy dips, brain fog, and hormonal disruption.
Neuroprotection
GLP-1 receptors in the brain support neuronal health, reduce neuroinflammation, and may protect against cognitive decline.
Cardiovascular Support
Reduces arterial inflammation, improves lipid profiles, and supports healthy blood pressure — benefits seen even at low doses.
Tirzepatide vs. Retatrutide: Which to Choose?
Tirzepatide (Dual Agonist)
GLP-1 + GIP receptor agonist. More established research base. Excellent for blood sugar management and anti-inflammatory effects. Generally well-tolerated at low doses. Good starting choice for most people.
Retatrutide (Triple Agonist)
GLP-1 + GIP + Glucagon receptor agonist. The glucagon component adds metabolic flexibility, enhanced fat oxidation, and additional energy expenditure. May provide broader metabolic optimization. Newer compound with growing research.
Universal Safety Guidelines
- 1Always establish baseline bloodwork before starting any stack
- 2Introduce one new compound at a time, waiting 1-2 weeks between additions
- 3Choose either Tirzepatide OR Retatrutide — never use both simultaneously
- 4Start all compounds at the lowest recommended dose and titrate up
- 5Keep a daily log of doses, timing, and any side effects
- 6Get follow-up bloodwork at 6-8 weeks to assess response
- 7Cycle compounds as recommended — more is not always better
- 8Store all reconstituted peptides in the refrigerator (36-46°F / 2-8°C)
- 9Use new syringes for each injection — never reuse needles
- 10Consult a healthcare provider, especially if on prescription medications
