What Are Peptides Used For? 4 Clinical Categories at Rebuild Regen

Peptides are used for 4 defined clinical categories at Rebuild Regen Medical Clinic, each targeting a specific biological mechanism through receptor-mediated signaling.

Category 1: Tissue Repair and Healing

BPC-157, TB-500 (Thymosin Beta-4), GHK-Cu, and KPV are used for tendon, ligament, muscle, and gut repair. BPC-157 upregulates growth factor receptors at peripheral injury sites. TB-500 activates actin to support cell migration and wound healing. These peptides are used by athletes with chronic or acute injuries and patients recovering from surgery or gut inflammation.

Category 2: Hormonal Optimization (Growth Hormone Axis)

CJC-1295, Ipamorelin, Sermorelin, MK-677, and GHRP-6 stimulate the body's own growth hormone release through GHRH receptor or ghrelin receptor activation. Elevated GH drives IGF-1 production in the liver, supporting body composition, recovery, sleep quality, and longevity. These are the most commonly requested peptides for anti-aging and performance optimization.

Category 3: Cognitive and Neurological Function

Semax, Selank, Dihexa, and SS-31 target brain function, neuroprotection, and mood regulation. Semax upregulates brain-derived neurotrophic factor (BDNF) and supports dopaminergic activity. Selank has GABAergic anxiolytic activity. These peptides are used for brain fog, anxiety, post-concussive symptoms, and cognitive performance.

Category 4: Metabolic and Weight Management

Semaglutide, tirzepatide, AOD-9604, and 5-Amino-1MQ address appetite, glucose regulation, and fat metabolism. Semaglutide and tirzepatide are FDA-approved GLP-1 and dual GLP-1/GIP agonists with clinical trial data showing 10% to 20% total body weight loss over 12 to 16 months. These are the highest-evidence peptides in clinical use.

How Rebuild Regen Selects the Right Category and Peptide

Peptide selection at Rebuild Regen Medical Clinic at 3320 N Federal Hwy #101, Lighthouse Point, FL begins with identifying the primary clinical goal. Labs inform which category is appropriate. The specific peptide within the category is determined by the mechanism most relevant to the patient's condition and goals. See the complete peptide therapy guide for all 17 peptides.

When Peptides Are Not Indicated

GH axis peptides are contraindicated in active cancer. GLP-1 agonists are contraindicated in medullary thyroid carcinoma and MEN-2. The consultation identifies contraindications before any peptide is recommended.
