We are at the forefront of Regenerative Medicine, offering cutting-edge treatments that focus on enhancing longevity, reversing the effects of aging, boosting vitality, and improving overall well-being. One of the exciting areas of Regenerative Medicine is the use of Peptides for both medical and therapeutic purposes.

However, it is important to note that the use of Peptides, whether prescription or non-prescription, should be done under the guidance of a qualified healthcare provider. Even non-prescription Peptides can have potential side effects or interactions with other substances, so it’s essential to consult with a healthcare professional before using them.  Always seek professional advice and guidance when using Peptides to ensure your safety and the effectiveness of the treatment.


The FDA regulates certain Peptides as medications and has recently announced a list of specific Peptides that they are nominating as Category 2 status.  We are currently reviewing all revised guidelines in an effort to remain compliant with FDA regulations.

FDA regulations can change over time. It’s crucial to stay up to date with the latest FDA regulations by visiting the official FDA website or consulting with a member of our team who is knowledgeable about the most recent guidelines. Please know that we take FDA regulations very seriously and actively monitor any changes or new announcements so that we remain compliant with respect to the use of Peptides.

What Are They and Why Are They Used?

  1. Anti-Aging: Peptides can stimulate the production of collagen, leading to firmer and more youthful skin. They may also promote tissue repair and regeneration, contributing to a more youthful appearance.
  2. Enhanced Energy: Certain Peptides can boost energy levels and endurance, making them appealing to those seeking improved vitality.
  3. Muscle Growth: Some peptides, like growth hormone-releasing peptides (GHRPs), can promote muscle growth and strength.
  4. Weight Management: Peptides like Melanotan may help with appetite suppression and weight loss.
  5. Cognitive Function: Certain Peptides may support cognitive function, memory, and mental clarity.
  6. Immune Support: Peptides can enhance immune function, potentially aiding in the body’s defense against infections.
  7. Healing and Recovery: Peptides have the potential to speed up tissue repair and recovery, making them popular among athletes.

Contraindications and Side Effects

While Peptides have many potential benefits, it’s crucial to use them under the guidance of a qualified healthcare provider. Contraindications and potential side effects can vary depending on the specific Peptide and individual factors. Common considerations include:

  • Allergic Reactions: Some people may experience allergic reactions to certain Peptides. It’s important to be cautious and consult a healthcare provider if you have allergies.
  • Dosage and Timing: The dosage and timing of peptide administration should be precise. Incorrect use may lead to side effects or lack of efficacy.
  • Interaction with Medications: Peptides may interact with other medications or medical conditions. It’s essential to discuss their use with a healthcare provider, especially if you have existing medical conditions or take other medications.

Peptides in Biohacking and Athletics

Peptides have gained popularity among biohackers and athletes for their potential to enhance various aspects of physical and mental performance. These individuals often seek peptides that promote muscle growth, improve recovery, and enhance cognitive function. However, it’s essential for athletes to be aware of regulations and policies related to the use of Peptides in their respective sports, as some may be prohibited.

Commonly Prescribed Peptides

The choice of Peptides can vary widely based on individual goals and needs. Some commonly prescribed Peptides may include:

  • Growth Hormone-Releasing Peptides (GHRPs): These are used for muscle growth and recovery.
  • Melanotan: Used for tanning and appetite suppression.
  • BPC-157: Known for its potential to support tissue repair and recovery.
  • Cerebrolysin: Used for cognitive enhancement.
  • Thymosin Alpha-1: Often prescribed for immune support.
  • GHK-Cu: Copper peptide used for wound healing, stimulation of collagen, reduce wrinkles, anti-inflammatory, heals nerves and increases/restores hair.
  • Thysomin Beta: Plays various roles in tissue repair, wound healing, anti-inflammatory, cardiovascular benefits and cell regeneration.
  • Semaglutide: Used primarily for type 2 diabetes and, in some cases, obesity and offers cardiovascular benefits. Known as glucagon-like peptide-1 (GLP-1) receptor agonists.
  • Tirzepatide: Similar to semaglutide, it interacts with GLP-1 receptors in the body to lower blood sugar levels, improve insulin sensitivity, and reduce appetite. This mechanism of action is beneficial for both diabetes management and weight control.
  • CJC-1295: Used in the field of anti-aging, regenerative medicine, and hormonal therapies. It is designed to stimulate the release of growth hormone (GH)

What is the Difference between prescription Peptides and non-prescription Peptides?

The difference between prescription peptides and non-prescription peptides lies primarily in how they are regulated, prescribed, and the intended uses for which they are approved. Here’s an overview of these two categories:

Prescription Peptides:

  1. Regulation: Prescription peptides are typically considered medications by regulatory agencies such as the FDA (Food and Drug Administration) in the United States. They are subject to rigorous testing and regulatory approval processes to ensure safety and efficacy for specific medical conditions or therapeutic purposes.
  2. Prescribed by Healthcare Providers: Prescription peptides can only be legally obtained with a prescription from a qualified healthcare provider, such as a physician or a nurse practitioner. These providers evaluate an individual’s medical condition and determine the appropriate peptide treatment.
  3. Medical and Therapeutic Uses: Prescription peptides are primarily used to treat specific medical conditions, such as hormone deficiencies (e.g., growth hormone deficiency), autoimmune diseases, and certain age-related conditions. These peptides are administered under the supervision of healthcare professionals.
  4. Regulated Dosage and Administration: The dosage, administration method, and treatment duration for prescription peptides are carefully regulated to ensure safe and effective use.

Non-Prescription Peptides:

  1. Regulation: Non-prescription peptides, sometimes referred to as “research peptides” or “cosmetic peptides,” are generally not subject to the same level of regulatory scrutiny as prescription medications. They may not have received FDA approval for specific medical conditions.
  2. Available Over-the-Counter: Some non-prescription peptides can be purchased over the counter (OTC) or online without a prescription. They are often marketed as supplements or for cosmetic purposes.
  3. Cosmetic and Wellness Uses: Non-prescription peptides are commonly used for cosmetic and wellness purposes, including anti-aging, skin rejuvenation, and muscle building. They may be available in the form of skincare products or dietary supplements.
  4. Less Stringent Regulation: Non-prescription peptides may not undergo the same rigorous testing and regulation as prescription medications. This can make it challenging to assess their safety and effectiveness, as well as their purity and quality.
