The formula for CSE Endurance IGF-1 contains just two ingredients: Insulin-like Growth Factor-1 for helping to fight various signs of aging and lactose for aiding in digestion. IGF-1 is commonly included in dietary supplements for anti-aging, and is usually derived from an animal source. However, this product explicitly states that it contains no animal products, and does not say what the source of the concentrate is.

According to the product’s website, the formula contains a 30C dilution of pure homeopathic recombinant IGF-1, and claims that it is a “clinically proven safe, effective, pure formula.”

The exact label information is not available.

IGF-1 is mainly produced by the liver and helps to mediate the growth-promoting effects of HGH and affects nearly every cell in the body. It is important for growth and is produced in greater abundance during childhood and adolescence, then slows around age 30. Excess production of IGF-1 could lead to gigantism in children or the hormonal disorder acromegaly in adults.

This product comes in the form of a chewable tablet and should be taken three times a day. It is best absorbed on an empty stomach, and the manufacturer recommends taking the tablets at least 30 minutes after eating. No food or beverages should be consumed within 20 minutes of taking the tablets, but plenty of water should be drunk throughout the day to help release toxins from the body, claims the company. The manufacturer recommends taking the capsules in 5-day cycle, taking a two-day rest every week.

This method may not be the most convenient for everyone, particularly those who need to eat first thing in the morning or who prefer to wake up with a cup of coffee. Capsule-based formulas are available in pills designed to be swallowed and do not come with so many restrictions.

While using this product, it will be important to remember to keep the body hydrated, and the advertising suggests that the product will “turbo-charge your workout” so it may increase energy levels. It is advised to use the product in conjunction with another product from CSE, their HGH formula, for best results.

When using supplements that are designed to have an impact on hormones, it is important to seek a high quality product; lower grade extracts could be contaminated, and may not be as effective. This is especially worrisome for this product, since it claims to be synthetically produced, but does not disclose what it is included in the formula.

Other products are available that contain high quality ingredients, including real HGH releaser, which can help increase the body’s natural production of HGH. Seek a product with the most proven ingredients.
