Most Commonly Used Peptides

That's exactly why we built Protocol AI — to help you calculate dosages, track usage, and manage your peptide stack in one place.

Below is a breakdown of some of the most commonly used peptides people are tracking inside the app.

CJC-1295 / Ipamorelin

A widely used growth hormone–supporting combination, often tracked for its role in:

• Supporting lean muscle development
• Reducing body fat
• Improving sleep quality and recovery
• Enhancing energy and overall performance

This is one of the most frequently logged protocols for users focused on body composition and long-term optimization.

BPC-157

A go-to peptide for recovery and repair, commonly used for:

• Supporting gut health and digestive function
• Reducing inflammation
• Promoting healing of muscles, tendons, and ligaments

Users often rely on Protocol AI to stay consistent with dosing — especially during injury recovery phases.

BPC-157 / TB-500 Blend

A powerful combination often used for full-body recovery:

• Accelerates soft tissue repair
• Supports joint and tendon health
• Helps manage inflammation

Tracking blended protocols can get complicated — this is where having precise dosage calculations and logs becomes critical.

GHK-Cu

A peptide commonly associated with skin and cosmetic benefits:

• Supports collagen production
• Improves skin elasticity and firmness
• May promote hair growth
• Aids in skin repair

Many users track topical and injectable usage separately inside the app to stay organized.

DSIP (Delta Sleep-Inducing Peptide)

Often used to support sleep and recovery:

• Helps regulate sleep cycles
• May improve sleep depth and quality
• Supports stress reduction

Because sleep protocols often require consistency, tracking timing and dosage is key.

NAD+

A popular compound for energy and cellular health:

• Supports metabolic function
• Helps improve focus and mental clarity
• Plays a role in cellular repair and longevity

Users frequently track NAD+ alongside other peptides to optimize overall performance.

Additional Peptides Users Track

Protocol AI is built to support any protocol, including more advanced or less common compounds:

• Dihexa — Cognitive performance and memory
• Epithalon — Longevity and sleep cycle support
• PT-141 (Bremelanotide) — Sexual wellness
• Selank & Semax — Focus, mood, and stress resilience
• Thymosin Alpha-1 (TA1) — Immune support
• Melanotan — Skin pigmentation

Why Tracking Matters

Peptides only work if they're used correctly — and consistently.

Protocol AI helps you:

• Calculate exact dosages based on your vial and reconstitution
• Log every injection or application
• Monitor your inventory so you never run out mid-cycle
• Stay consistent with your protocol over time

Build Your Protocol with Confidence

Whether you're just getting started or running a complex stack, having a system matters.

Protocol AI gives you the structure, precision, and visibility to stay dialed in.
