What Are Peptides?

Aging, diet, lifestyle, and medical conditions are just a few factors that can impact how you feel and function. Thiesen MD offers peptide therapy, a personalized treatment to restore balance within your body. Peptides, in layman's terms, are short strings of 30 – 40 amino acids that act as signaling molecules in the body, and instruct various cells and molecules on what functions to perform. To date, there are more than 7,000 known peptides in the human body, and all of these peptides have a wide range of functions. Peptide therapy mimics the naturally occurring peptides in your body to improve a number of age-related symptoms. We offer weight loss peptides, peptides for metabolism boosts, peptides for memory, epithalon for rejuvenation, and more. Our team customizes every aspect of this treatment to meet your unique needs. Call one of our locations in North Andover, MA, Bourne, MA, or Cranston, RI to schedule a consultation to learn more about how peptide therapy can benefit you.

What Is Peptide Therapy?

With many unique peptides with their own individual functions, peptide therapy offers a personalized solution tailored to your specific needs. During your consultation, we will discuss your concerns and symptoms to formulate a specialized treatment plan.

Peptides act as signaling molecules in the body, which influence various physiological processes and promote healing, tissue repair, and rejuvenation.

These bioactive peptides can target specific areas such as muscle growth, immune system support, cognitive enhancement, weight management, and skin rejuvenation. By leveraging the power of peptides, therapy treatment can help improve athletic performance, boost immune function, enhance cognitive function, support weight loss goals, and promote youthful-looking skin.

Peptide therapy is known for its high safety profile and minimal side effects. The treatment is typically well-tolerated and can be customized to suit individual requirements.

Who Should Have Peptide Therapy?

Though our bodies produce peptides naturally, the rate of production varies from person to person. For this reason, peptide therapy can play a pivotal role in health optimization for both men and women. Thiesen MD peptides are bio-identical, meaning they have the exact same structure as the peptides already naturally synthesized by the body.

Additionally, amino acid and peptide production has been shown to decline with age. Decreased amino acid production can result in a variety of symptoms, including:

  • Excess body fat, especially at the mid-section
  • Depression
  • Anxiety
  • Fatigue
  • Increased heat/cold sensitivity
  • Reduction in muscle and lean body mass
  • Decreased exercise tolerance
  • Reduction in bone density

What Are the Benefits of Peptide Therapy?

There are a wide range of benefits associated with peptide therapy. Some of the main benefits our New England patients experience include:

  • Increased production of Human Growth Hormone (HGH)
  • Boost in energy
  • Improved skin elasticity
  • Muscle building
  • Optimized physical and athletic performance
  • Fat burning
  • Weight loss
  • Repair damaged muscles and tendons
  • Increased sex drive
  • Enhanced quality of sleep and combat insomnia
  • Enhanced calcium retention
  • Improved memory and cognitive focus
  • Resolved depression and anxiety
  • Improved immune function

What Can I Expect after Peptide Therapy?

If you've recently undergone peptide therapy at Thiesen MD, you may be wondering what to expect post-treatment. This innovative therapy is known for its range of benefits, but what happens after the session? Some results to watch for include:

  • Initial Response: Within the first few hours to days, you may feel an uplift in mood and energy. However, the real benefits often take time to manifest.

  • Short-Term Effects: After a week or so, you may begin to notice improved sleep quality and enhanced focus. Some patients even report better skin texture.

  • Long-Term Outcomes: Over the course of several months, expect more pronounced results like increased muscle mass and reduced body fat. Consistency is key for achieving these results.

  • Follow-Up Sessions: Most treatment plans recommend periodic follow-up sessions for monitoring and adjustments.

So if you're under our care in New England, rest assured—you're on a journey to optimal wellness. Call us to schedule your next appointment!

I am absolutely thrilled with my Genius and Ultra laser combination treatment performed by Cecelia Paige at Thiesen MD. My skin feels tighter and looks more even toned and textured. I even notice a reduction in fine lines and improved acne scarring. I will definitely be returning in the near future for additional treatments.
