That is, if you can get your hands on IGF-1 supplements that are legal, that work without side effects, and that don’t require injections.
Specifically, deer antler extract sprays are now being offered as a natural, safe alternative to synthetic steroids that contains IGF-1.

This compound, available in both artificial and organic forms, can indeed provide incredible support for athletes, as well as for victims of muscle-wasting disorders.

IGF-1 Reviews – Healing Injury
Related Topics
One of the main reasons that IGF-1 supplements are legally prescribed is for the healing of wounds.
For example, IGF-1 injections are frequently prescribed by doctors for patients with broken bones, torn ligaments and muscles, and deep tissue damage associated with high intensity trauma, such as a vehicle accident.
IGF-1 is a protein that is normally released by the body in times of physical trauma. It bonds with receptors which instruct cells to divide and grow.
This action results in the formation of scar tissue, and the building of new muscle, one the most popular benefits cited in IGF-1 reviews. We often see IGF-1 prescribed for people suffering from muscular degeneration diseases such as MS or MD. More benefits of an IGF spray can be found here.
But these sprays are regulated heavily to prevent overuse. When there is an extreme overabundance of IGF-1, it can instruct these same cells to mutate into cancers or tumors.
IGF-1 Reviews – Stamina and Muscle Building
The most popular off-label use for IGF is as a workout-enhancing bodybuilding supplement. The same muscle-growing qualities which make IGF-1 ideal for healing and muscle wasting support also can build mass and strength in healthy bodies at a dramatic rate.
Weightlifters, runners, swimmers, and athletes in every major league sport use some form of IGF to gain a critical training edge. In general, this practice is frowned upon and banned by governing agencies and anti-doping assemblies.
At the casual level, bodybuilders can purchase some form of IGF-1 through an internet grey market, avoiding doctor care and prescription requirements. This is a very risky practice, as the individual intricacies of calculating dosage are typically not easy for a layman to master.
As IGF-1 is only bioavailable when it can avoid the digestion process, these grey market drugs must be injected, further amplifying risk to unsupervised amateurs. However, deer antler sprays offer a way around this because they do not require injections and can be purchased without a prescription.
IGF-1 Reviews – Sexual Health
In ancient Chinese medicine, a form of IGF-1 was used as a cure-all for men’s and women’s sexual dysfunction. Harvested form the antlers of wild deer and antelope, which are well-known to use ample amounts of IGF-1 to prompt rapid bone growth, these folk remedies could cure impotence and heighten libido. Today, many deer antler extract remedies are popular for the very same reason.
In addition to all of the other known benefits of IGF-1 supplementation listed above, antler products can deliver heightened sexual arousal and a natural solution to ED. This quality is frequently used as a main selling point in IGF-1 reviews, more so even than muscle building effects.
Antler extracts are able to bypass the digestion/ingestion problem by delivering the compound to the blood through an under-the-tongue spray. This review offers a comprehensive look at IGF and sexual function.
User Side Effects and Safety
Of course, a prime concern of almost all IGF-1 reviews is the fear of side effects. The balance of human growth factor and nerve growth factor hormones is delicate. For the vast majority of healthy adults, this balance is kept in check by the pituitary gland throughout life.
By introducing large amounts of added growth hormone into the mix, hormone cell receptors can be over-stimulated and signal unwanted growth.
This growth will sometimes come in the form of tumors and cancers. Lesser side effects include the appearance of gender-reversed sexual characteristics, such as facial hair on women, and large breasts on men.
Amazingly, many bodybuilders who take an abundance of growth hormones are willing to live with these risks. Side effects can be prevented by very thoughtful use of growth hormone products, adhering carefully to recommended dosing and cycle timing.
What Products Are Rated Most Effective?
The rising star of growth factor supplementation is the deer antler extract. Already proven through centuries of use in Chinese medicine, we now see deer antler sprays marketed across a plethora of bodybuilding websites. Across message boards and weightlifting forums, the reviews of these products is good to excellent. Most users note gains to muscle strength and bone density, as well as the added benefits of sexual potency.
A recent study done by news organization CNBC found a demonstrable improvement in lean muscle gain for athletes who used deer antler sprays over those who didn’t. This is a promising finding for supporters of the treatment. Find out the best benefits that deer sprays have to offer here.
The majority of IGF-1 reviews are right to call out the benefits for muscle growth, athletic performance, overall immunity, and sexual power such supplements can deliver. Concerns about the difficulties of supplementing easily degraded growth hormones can be allayed with the use of sub-lingual sprays.
While there is a lack of mainstream objective scientific analyses so far, early results indicate that these sprays could be a promising option for a broad range of people seeking muscle and bone support, as well as an alternative to pharmaceutical sexual enhancement drugs. The latest research is summarized in this article.
