Peptide Therapy Gives Your Body Its Own Natural Tools to Help It Perform at Its Best

Humans evolved for millions of years with peptides as a natural part of our biology. They act as signals for DNA, genes, hormones, and neural tissues. Since they occur naturally, your body already knows what to do with them, unlike drugs and other treatments that can have serious side effects.

By powering your natural biology, peptide injections stimulate a cascade of positive effects that promote weight loss, muscle gain, joint and tendon healing, and more…

…all backed by the latest science.

The Science Behind What Peptides Do

Peptides aren't hype...they're backed by some of the most rigorous scientific research, including some double-blind, placebo-controlled studies. Learn more about the growing body of scientific literature on peptides, and how they power your body's own biology to perform at its best.

Peptides for Weight Loss

Peptide therapy is showing promise as a breakthrough treatment for weight loss, offering hope to those who have tried diet, exercise, and other interventions without success. The best peptide for weight loss is the semaglutide injection.

New England Journal of Medicine: This rigorous, double-blind trial of 1961 adults, semaglutide treatments resulted in an average weight loss of 15%. The average weight loss for the group was 34 pounds, and the average waist reduction was 6 inches.[1]

The Journal of the American Medical Association: In a randomized trial of 611 people—composed of more than 80% women and an average age of 46 years—semaglutide treatments resulted in a 16% reduction in body weight, and 40% of the participants saw reductions of more than 20%.[2]

Peptides for Muscle Growth

Our lean muscle support Peptide can be helpful for bodybuilders since they stimulate human growth hormone (HGH). Peptides also promote the healing of nagging injuries that can thwart exercise.

Today’s Therapeutic Trends Journal: Lean muscle support peptide treatments demonstrate an increase in lean body mass, decreased fat mass, and modest increases in bone mineral density. It’s shown to boost circulating levels of insulin-like growth factor-I, and improve body composition.[3]

Journal of Molecular Endocrinology: Human growth hormone (HGH) improves aerobic and anaerobic exercise capacity, while also increasing muscle size.[4]

Peptides for Skin

Peptides also show promising benefits for skin health and appearance. At Prime IV, we don’t work with topical creams, but with injection therapies that help rebuild skin from the inside out. Again, the stimulation of human growth hormone (HGH) plays a significant role here.The most effective peptide for skin is the healthy glow peptide formula.

Translational Urology and Andrology Journal: The healthy glow peptide formula has been shown to significantly increase skin thickness in both males and females in just 16 weeks.[5]

New England Journal of Medicine: HGH improvements resulted in a 7.1% increase in skin thickness in a trial of older men.[6]

Peptides for Cardiovascular Health

The semaglutide peptide has been proven to safely reduce cardiovascular risk factors in patients that are already experiencing established cardiovascular disorders.

National Library of Medicine: A post-hoc analysis shows that there is approximately a 24% reduction in cardiovascular adverse events that is achieved by semaglutide. [7]

National Library of Medicine: Semaglutide can be definitively considered as a quintessential of GLP-1 receptor agonist targeting diabetes. The anti-hyperglycaemic effects of semaglutide have been firmly established in multiple clinical trials on adults, elderly and obese type 2 diabetic patients with and without cardiovascular disease.

Frequently Asked Questions

What are peptides?

Peptides are short chains of amino acids that are linked together by peptide bonds, which often act as hormones and signaling molecules.

Peptides can act as signaling molecules by binding to specific receptors on the surface of cells. When a peptide binds to its receptor, it can initiate a series of events inside the cell that leads to a specific cellular response. This process is known as signal transduction.

There are many different types of peptides that act as signaling molecules, and they play a wide range of roles in the body. Some peptides are involved in the regulation of appetite, metabolism, and cardiovascular function. Others act as neurotransmitters, transmitting signals between nerve cells in the brain and nervous system.

How are peptides administered?

Our peptides are administered via a subcutaneous injection. Subcutaneous injections are often preferred for the administration of peptides and other substances (like insulin) because they are less painful and are less likely to cause discomfort or irritation. They are also relatively easy to administer, as they do not require specialized training or equipment.

Subcutaneous injections involve injecting a substance just below the skin, typically into the fatty tissue layer. These injections are typically less painful than other types of injections, such as intravenous or intramuscular injections, because they do not involve injecting the substance into muscle tissue.

Do I need a prescription from a doctor to receive peptide therapy?

Yes, you do need a prescription for peptides. This is why your initial onboarding will include a consultation with one of our trained physicians in order to see if you qualify for peptides. If you qualify, then our physician will write the prescription for you.

Are peptides safe?

Peptides are generally considered to be safe when used as directed. However, as with any substance, there is a potential for side effects or adverse reactions. The safety of peptides can vary depending on the specific peptide and the intended use.

Some peptides have been extensively studied, with over 60 being FDA-approved, and are used widely in medical and research settings. These peptides are generally considered to be well-tolerated and have a low risk of serious side effects.

It is important to follow the recommended guidelines for using peptides, including the recommended dosage and frequency of use. It is also important to be aware of any potential side effects or contraindications and to seek medical advice if you experience any adverse reactions.

It is important to follow our expert healthcare provider’s instructions and advice when using peptides, as they are best equipped to determine the appropriate treatment plan for you based on your individual needs and medical history.

Do peptides have side effects?

Some peptides have been developed as pharmaceuticals and are used to treat a variety of medical conditions. Like any medication, peptides can have side effects, although the specific side effects will depend on the specific peptide being used.

Common side effects of peptides include:

  • Nausea
  • Headache
  • Dizziness
  • Flushing
  • Rash
  • Itching
  • Swelling at the injection site

Some peptides may also have more serious side effects, such as allergic reactions, organ damage, or changes in blood pressure. It is important to discuss the potential side effects of any peptide with a healthcare provider before starting treatment.

Are peptides hormones?

Peptides are small molecules that are composed of chains of amino acids, which are the building blocks of proteins. Some peptides have hormonal activity, meaning that they can affect the way the body’s hormones function.

What Prime IV Clients Are Saying About Peptides

“I lost 33 lbs and 8% body fat in 3 months. Prior to semaglutide, I had crazy sugar cravings that are now gone. While on semaglutide, by default, you decrease your portion sizes as you get full quickly. You look at food differently and you feel your best when you fuel your body with higher protein than carbs.”


I lost 40 lbs in 4 months! I did the diet and exercise thing for over a year, but didn’t see the success I wanted. When I heard about semaglutide and what it could do to accelerate my weight loss and health goals, I was on board. After the first week the weight started falling off and I was sold. Now I have so much more energy and feel so much better."
