Frequently Asked Questions

What’s the difference between IGF-1 and HGH?

One of the differences is that IGF-1 is a peptide (protein produced by the liver). HGH, human growth hormone, is a hormone secreted by the pituitary gland. IGF-1 has immediate effects, whereas HGH has a longer loading period.

What are the benefits of taking IGF-1?

IGF-1 offers a direct and impressive opportunity to help patients with both age and disease management. It helps regulate fat for use as energy, increases rates of protein synthesis, and has positive effects on body composition and metabolism for increased lean muscle mass and decreased adiposity.

How is IGF-1 administered?

It is administered via a subcutaneous injection either once daily or twice daily, depending on the dosing prescribed by the participating physician.

What is the difference between LR3 IGF-1 and non-LR3 IGF-1?

LR3 IGF-1 is a Long Chain Recombinant of IGF-1, which basically means that the sequence of IGF-1 has been biologically extended through a proprietary process to increase the potency and duration of the peptide. It essentially allows the drug to be administered once daily rather than twice daily by increasing the half-life up to 20-30 hours, compared to the regular IGF-1 which has a half-life of approximately 8 hours.

How long before it starts working?

IGF-1 begins working immediately after administration. There is no “loading” phase like there is for hormones, such as HGH.

Are there any side effects?

IGF-1 has few reported short-term or long-term side effects at any level of dosage. However, it is important to note that while taking IGF-1, it should be taken with a meal and not before bedtime. This is because it may cause hypoglycemia, and create very vivid dreaming that may cause restless sleep.

Is it going to stop my natural production of IGF-1?

No. IGF-1 not being a hormone replacement means that the body’s natural production of the peptide will not slow down or shut off.

How do I get a prescription for IGF-1?

To obtain a prescription from a physician in our network of prescribers. For your convenience, we have physicians available who offer phone consultations. Once a physician determines that you are a good candidate for IGF-1 supplementation, your prescription will be compounded in our FDA-certified pharmacy and delivered to your home.

Where do we get our IGF-1?

Our IGF-1 is compounded here in the U.S. by pharmacies that meet state and federal requirements and pass inspection regulations, and are tested for purity, dosing, and sterility. We want you to receive the highest quality product with each order.

What is the dosing? How much in each vial?

Genetics Health offers two forms of insulin growth factor, IGF-1 and LR3 IGF-1. The LR3 comes in a liquid version, in vials of 620mcg, or 6.2mL. Our lyophilized version comes in vials of 300mcg which is to be reconstituted with 3mL of bacteriostatic water. This keeps the 1:1 ratio for dosing, for example: 20mcg = 20 units, 30mcg = 30 units, etc. The dosing per patient is dependent on your doctor’s recommendation.

What do you get when you receive your IGF-1?

With each order of IGF-1 our patients receive a sufficient quantity of syringes as well as alcohol wipes. The package also includes a booklet that describes in detail the storage, handling, administration, and product information, of IGF-1.

What is the “best use by date” of each vial?

IGF-1 has an expiration date of 6 months after creation for the lyophilized version, and 90 days (3 months) after creation for the liquid version.
