Carmen Gnatenco MD, IMBC: Peptide Therapy
for Performance, Recovery & Longevity in Palos Heights.

Our medical team offers physician-supervised peptide protocols designed to support muscle recovery, metabolic health, and overall vitality. Every plan starts with a comprehensive consultation so our providers can help you understand which options may be appropriate for your goals.

What Is Peptide Therapy?

Peptides are short chains of amino acids that occur naturally throughout the body and are involved in a wide range of physiological processes. In a medical wellness setting, peptide protocols are used to help support the body’s own processes related to recovery, metabolism, and overall function. At CGnature Medical, peptide therapy is offered as part of an individualized plan built around your health history, goals, and provider guidance, not as a one-size-fits-all product.

FDA Disclosure

Many peptides used in wellness and performance settings, including some offered by CGnature Medical, have not been approved by the U.S. Food and Drug Administration (FDA) for the specific uses described on this page. Peptides may be compounded by a licensed pharmacy under an individualized prescription following a consultation with one of our medical providers. Compounded medications are not FDA-approved, and their safety and effectiveness for these uses have not been independently evaluated by the FDA. Peptide therapy is not appropriate for everyone. Individual results vary and are not guaranteed. This page is for general educational purposes and is not a substitute for a one-on-one medical consultation.

Peptides We Currently Offer

prices start at 199$ per month.

Pricing varies based on the type of peptide or peptide stack, dosage, and clinical indication.

CJC-1295 / Ipamorelin peptide vial

CJC-1295 / Ipamorelin

CJC-1295 / Ipamorelin is a growth hormone secretagogue combination. CJC-1295 extends the growth hormone pulse and Ipamorelin triggers a clean, selective GH release without affecting cortisol or prolactin. Together they improve sleep quality, lean muscle development, fat metabolism, skin tone, and recovery speed. The protocol runs 1 to 3 months on, followed by 2 to 3 months off.

Tesamorelin peptide vial

Tesamorelin

Tesamorelin is a growth hormone-releasing hormone (GHRH) analog specifically studied and FDA approved for reduction of visceral abdominal fat. The protocol runs daily, 5 days on and 2 days off, in 3-month cycles with 2 months off between them. It is frequently combined with GLP-1 medications for patients pursuing weight loss alongside body re-composition. Patients working on body re-composition and visceral fat reduction often combine and alternate Tesamorelin with other peptides under our medically supervised Weight Loss Treatment Plan for a more complete metabolic approach.

BPC-157 peptide vial

BPC-157

BPC-157 (Body Protective Compound) is derived from a protein naturally present in gastric juice. It is used for tendon and ligament repair, gut lining integrity, joint recovery, and systemic inflammation reduction. The depth of BPC-157 research is significant. A review in Current Pharmaceutical Design summarizing over two decades of BPC-157 preclinical research covering musculoskeletal, gastrointestinal, and systemic healing outcomes supports its use in tissue repair protocols.

TB-500 peptide vial

TB-500

TB-500 (Thymosin Beta-4) promotes systemic tissue repair and anti-inflammatory signaling throughout the body, making it effective for patients with widespread injury history or high athletic demands. Research published in the Annals of the New York Academy of Sciences confirms Thymosin Beta-4's role in actin regulation, stem cell mobilization, and multi-tissue healing responses.

Wolverine Stack BPC-157 and TB-500 peptide vial

Wolverine Stack (BPC-157 + TB-500)

Wolverine Stack (BPC-157 + TB-500) is the combination of BPC-157 and TB-500, prescribed together for patients who need comprehensive muscle and joint repair and recovery support. The combined protocol runs 1 to 3 months on and 2 months off, with dose titration. This is the most requested recovery protocol for active patients who wish to improve physical performance and anyone dealing with chronic musculoskeletal issues.

GHK-Cu peptide vial

GHK-Cu

GHK-Cu (GLOW and KLOW stack, Copper Peptide Blends) is one of the best-researched peptides and combination for skin regeneration and hair restoration. It stimulates collagen synthesis, promotes wound healing, and activates hair follicle signaling. The protocol is 30-60 days on, 30 days off, with a split-dose structure. Published peer-reviewed research on GHK-Cu is indexed in the PubMed database, where clinical studies on copper peptide activity in tissue repair, collagen synthesis, and wound healing support its use in regenerative protocols. Patients focused on hair, skin, muscle and joints restoration and repair, post-op recovery, sport injuries, severe osteoarthritis and inflammatory conditions, often combine GHK-Cu with BPC-157/TB-500, KVP, CJC/Ipamorelin.

MOTS-c peptide vial

MOTS-c

MOTS-c is a mitochondrial-derived peptide that supports cellular energy production, metabolic efficiency, and physical endurance. It is particularly effective for patients with fatigue, low exercise tolerance, or metabolic slowdowns that do not respond to diet and training adjustments alone. MOTS-c is frequently paired with our NAD+ Treatment Plan, addresses cellular energy and cognitive performance through a complementary pathway.

Epithalon peptide vial

Epithalon

Epithalon is a tetrapeptide studied for its effects on telomere elongation and circadian rhythm regulation. It is used in longer-term anti-aging protocols for patients focused on healthspan rather than acute symptoms. Epithalon is typically run in defined cycles and often combined with NAD+ and MOTS-c for comprehensive cellular protection.

Semax peptide vial

Semax

Semax is a synthetic cognitive peptide that supports focus, neurological resilience, and mood regulation. It is prescribed for patients dealing with executive burnout, persistent brain fog, post-stress cognitive decline, or those seeking a neurological edge for patients with cognitive deficits alongside current prescription medication for dementia, supplements and physical protocols.

Selank peptide vial

Selank

Selank (a.k.a. TP-7) is a synthetic neurocognitive peptide, a pharmaceutical capable of delivering cognitive and neuroprotective benefits. Apart from its central nervous system benefits, it's also used in Europe as a drug for managing anxiety and other mood disorders. Selank was developed in Russia by the Institute of Molecular Genetics as an analog of tuftsin, a natural peptide from a region of the antibody immunoglobulin G. While tuftsin's role is in modulating the immune system function, Selank shows neuro-hormonal and biochemical enhancements related to improving mood and the central nervous system protective mechanisms. It's known as 'natural Xanax', without the side effects and addictive potential of benzodiazepines.
