IGF-1 and Bodybuilding, IGF-1 LR3 Side Effects
IGF-1 LR3, Long R3 IGF-1, IGF-1- Insulin-like Growth Factor - is an experimental drug that represents the next generation in performance enhancing in bodybuilding athletes. This peptide hormone also has the promise of becoming the ultimate fountain of youth.
As the world has finally caught on to the fact that world-class athletes from all sports have been using steroids and other performance enhancing drugs (PEDs), the athletes themselves have moved on to the next generation of substances.
Long R3 IGF-1 is mainly secreted by the liver as a result of stimulation by Human Growth Hormone (HGH). Almost every cell in the human body is affected by IGF-I, especially cells in muscle, cartilage, bone, liver, kidney, nerves, skin, and lungs. In addition to the insulin-like effects, IGF-I can also regulate cell growth and development, especially in nerve cells, as well as cellular DNA synthesis.
IGF-1 LR3 Benefits:
- Stimulates muscle growth and has been shown to benefit the heart (a muscle).
- Encourages the absorption of Chondroitin Sulfate and Glucosamine Sulfate (also found in Velvet Antler).
- Regenerates nerve tissue
- Helps burn fat, increase protein transport into cells, and reduce protein breakdown
- Improves the production of white blood cells
- Decreases LDL Cholesterol
IGF-1 LR3 is a hormone just like HGH, but IGF-1 is the most important growth factor that the body produces. IGF-1 is much more powerful than HGH.
Currently the license to conduct human trials using IGF-1 is held by biopharmaceutical company Tercica and is limited to the study of children suffering from growth failure due to IGF-1 deficiency.
Even though the human study of IGF-1 LR3 is extremely narrow and limited to kids, the fact that this substance has been studied on rats and humans and is in the hands of people in labs means that the genie is out of the bottle.
IGF-1 has been used in lab studies since at least the late 1990s; so many people have had access to this drug for quite a long time. And there are people with tons of money who would love to get their hands on this stuff.
IGF-1 LR3 has produced some amazing results in lab rats. Now before you get all over me for talking about success with lab rats, you have to realize that this success with lab rats did lead to the human trials. And the results of the tests with lab rats have been astounding.
The benefits from IGF-1 are so astounding - and offer such promise to humans - that back in 2002, H. Lee Sweeney, Ph.D., Professor and Chairman of Physiology at the University of Pennsylvania and a recognized expert on the subject of the genetic enhancement of skeletal muscle, spoke to the World Anti-Doping Association with regard to the muscle building and regenerating properties of IGF-1.
In 2002, speaking before The President’s Counsel On Bioethics, Dr. Sweeney was of the opinion that the advent of genetically engineered athletes was not imminent and that studies needed to be done in order to determine the safety and long-term effects of IGF-1.
To think that using IGF-1 LR3 to build a better athlete is off in the future, and that this hormone won’t be used until human safety studies can be done, is to ignore the history of how these drugs have been used by athletes. Dr. Sweeney’s position is one of wishful thinking. And I mean no offense to the doctor in any way.
Going back to the HGH situation, bodybuilders were using this hormone in the mid-’80s well before people totally understood how and what this drug really could do. To this day there are many unknowns that are associated with the use of HGH, including the debate as to its safety, yet the use of this hormone is widespread in bodybuilding, in real sports, and in the general population.
Here are some of the reasons why IGF-1 will revolutionize the world of performance enhancing substances, and why athletes will risk - are risking - their health to use it.
IGF-1 has been shown to increase the rate and extent of muscle repair after injury and increase the rate of muscle growth from training. And not only are existing muscle fibers repaired quicker, IGF-1 is responsible for hyperplasia, which is an increase in the amount of muscle fibers.
Hyperplasia is the Holy Grail of performance enhancing benefits, and occurs when muscle fibers actually split, therefore creating more muscle fibers. Hypertrophy is simply an increase in the size of the existing muscle cells, and occurs from weight training and from steroid use. Hyperplasia plus hypertrophy equals a new breed of amazing athlete.
But wait, there’s more:
Rats that were given IGF-1 and did nothing were bigger and stronger than rats that weren’t given IGF-1 but exercised. And I’ll bet you guessed that rats that were given IGF-1 and exercised were the biggest, strongest rats in the house. The positive effects of IGF-1 on the rats continued for months after the rats stopped getting the supplemental hormone, whereas the exercising rats immediately lost size and strength as soon as they stopped exercising.
In another study the muscle fibers of 27-month old rats - old age for rats - that were given IGF-1 during middle age, exhibited no deterioration of muscle fibers that indicate the classic and inevitable signs of aging. These rats did not lose any fast twitch muscle fibers - the fibers responsible for power and speed - and had the same speed and power output that they had when they were six months of age.
To quote Dr. Sweeney, “So we were able to conclude that IGF-1 could prevent all of the hallmarks of age-related atrophy and loss of skeletal muscle function in mammalian aging, at least based on the rodent model, and now we’re hoping to pursue this in larger animal models.”
Dr. Sweeney also says that IGF-1 could be used as an instant muscle builder for members of the general population.
And here’s the final and most compelling reason why IGF-1 is being used right now, and why the demand for this hormone will increase exponentially as time goes by: IGF-1 is undetectable by both blood and urine testing. Because IGF-1 can be injected directly into the muscle, it never enters the blood stream. Therefore, a muscle biopsy is the only way to determine if a person has used IGF-1. And the anti-doping forces will never, ever be allowed to take muscle biopsies from athletes.
In a January 18th, 2004 New York Times Magazine cover story by Michael Sokolove, Dr. Sweeney says (page 30) that after presenting his IGF-1 info at an American Society for Cell Biology conference he was contacted by a high school football coach from Pennsylvania who wanted Dr. Sweeney to treat his entire team. Do you think by now world-class athletes - with world-class money - are interested in IGF-1?
Included in this article (page 28) were additional details with regard to the results of studies, in which rodents given IGF-1 before birth and at four weeks of age experienced a 35% increase in strength in targeted muscles, did not lose any size and strength as they aged and did not lose any of these gains when they stopped training.
Later on in the article Dr. Sweeney admits that athletes could already be using IGF-1. Elisabeth Barton, an assistant professor who was involved with Dr. Sweeney’s studies, says that creating a human athlete along the lines of these super mice “is easy.”
She goes on to explain, “It’s a routine method that’s published. Anyone who can clone a gene and work with cells could do it. It’s not a mystery.”
Dr. Sweeney added that there’s no limit to what can be done with IGF-1 and gene therapy with regards to building a better athlete. To make a sprinter faster Sweeney said, “I’d put the whole leg on bypass. I would put (IGF-1) in through the blood. It would be more efficient than injections (directly into the muscle), which you would need a lot of because you’re dealing with large muscles. But this is nothing a vascular surgeon couldn’t do.”
So to recap, IGF-1 provides almost permanent muscle-creating, muscle-repairing, and anti-aging benefits and is totally undetectable. Do you think athletes are chomping at the bit to get their hands on this stuff?
The legitimate scientific world is following the proper protocols with regards to IGF-1, but the underground world is not bound by the same rules. Legitimate science - rightly so - is nowhere near ready to allow “us” to start using this stuff. But this isn’t the point.
The point is that there is a substance out there that scientists are cautiously touting as an instant muscle builder and a fountain of youth, and for some people this is all that they need to hear. These people aren’t going to wait - haven’t waited - for legit science to bless the use of IGF-1 LR3 for human consumption before they go out and inject themselves with it. Adverse side affects? Please.
In 2004 the leading experts on the subject admitted that this gene therapy could already be in use, and that the technology and knowledge is such that the process to deliver it isn’t complicated. Two and a half years later this circle of knowledge, and use, is that much larger.
Knowing how HGH was purloined by people who were too impatient to wait for legit science to do it’s thing, bodybuilders and real athletes did what they had to do to get it and use it, danger be damned. There’s no reason to think that the same situation isn’t occurring right now.
Bodybuilding web sites, bulletin boards, and chat rooms are awash with discussions about IGF-1, what it can do, how to use it, and what drugs to stack with it. There’s talk that underground labs are synthesizing IGF-1, HGH, and a host of other substances.
According to Chemical Muscle Enhancement, a well-known underground PED guidebook written by Internet steroid guru L. Rea and available via download or through Amazon, IGF-1 has even been altered to increase its effectiveness, making IGF-1 ten times more potent (pages 134-136 of Chemical Muscle Enhancement). Several websites make reference to this altered form of IGF-1 - known as DES (1-3) IGF-1. This version of IGF-1, Insulin-like Growth Factor is also refereed to as Lr3IGF-1 (Note: Lr3IGF-1 is 2-3x more potent than regular IGF-1).
IGF-1 is being synthesized and altered in underground labs and is being sold on the black market. Bodybuilders are using IGF-1 and it is illogical and naive to think that some athletes at the highest level of sport are not using IGF-1 right now. People who you’ve probably never even heard of are using it just as there are well-known athletes who have already benefited from the use of IGF-1.
People did crazy things to get their hands on HGH 20 years ago, did crazy things to get their hands on whatever the next-generation drug was 30 years ago, and it’s no different today.
While in some sense the public has finally caught on to “steroids,” the high-tech, high-minded athletes have moved on, light years ahead of what the public can conceive of and comprehend. “Steroids” is the Model-T Ford; IGF-1 is the USS Enterprise or the Millennium Falcon.
With each advance in the field of PEDs the underground has been responsible for the spread of knowledge and supply of these drugs. Advances in technology and today’s free flow of information have made it possible for underground labs to synthesize, alter, and deliver into the body drugs of all types.
With money, fame, and even a kind of immortality involved, there’s no telling what some people will do. The mindset of the PED user is that IGF-1 can deliver all three of these.
The use of PEDs up until this point has pretty much been a black and white issue, but with this next generation of substances now available the debate will get much more complicated. PEDs are NOT going to be eradicated, their use will become more widespread as the benefits that they provide become more and more attractive to potential users.
Tips for maximizing your Insulin-like growth factor, IGF-1 LR3:
If you are not using ZMA currently, you should start it up before starting the IGF-1. Zinc plays a very crucial role in enzyme activation of IGF-1. It also increases blood plasma levels of total and free IGF-1. A deficiency actually hinders IGF-1 formation.
Since IGF-1 LR3 is such a new peptide, there are no long term studies about the IGF-1 side effects.

hi guys! can i now more about how can i use igf1?thank you
October 6th, 2007 at 1:13 pm
I have a friend who is quadraplegic and has always been a bodybuilder. he has done a lot of research on IGF-1 and has asked me to find this so he can, at least, be able to keep some of his muscle mass. I appreciate your help. thanks, nikki

This seems to be a great alternative to the traditional ‘drugs’ we’ve been taking. what are the effects on high blood pressure kidneys and liver.
Kind regards
Rudy
Please tell me if there is any known side effects

IGF-1 LR3 is such a new peptide there is little long term empirical data on its effects. Remember IGF-1 is the anabolic agent of HGH so you tend to see results in weeks, as apposed, to the six months it takes HGH to really take effect.
IGF-1 is a research peptide, it hasn’t been approved by the FDA for use as a pharmaceutical and it is currently being used and researched for nerve tissue repair, possible burn victims, as a possible aid in muscle wasting for AIDS patients, and also insulin resistance.

Will Igf activate cancer cells? will it build more muscle where i don’t want to such as the thighs? in stead of chest and upper arms even though i don’t get to do much lifting at all, i need to increase my strength? also would it make the face any bigger? i want the face to slimmer/younger. im 35 yrs of age what else comes close to to as potent and powerfull, thus safe? is it organic?
i need to know what the price of the products are and would cost.

IGF-1 is a naturally produced growth factor that is expressed in a number of tissues in the body. With regards to human muscle hypertrophy, work is currently being done to understand the biochemical pathways that IGF-1 activates. In Skeletal muscle, IGF-1 enhances muscle satellite cell proliferation and differentiation which MAY lead to enhanced tissue repair and contribute myonuclei to exsisting muscle fibres. I caution the notion of hyperplasia. There is no conclusive data to indicate that hyperplasia is induced by IGF-1.
In cell cultures (dish full of muscle precursor cells call myoblasts) the ectopic expression of IGF-1 will induce differentiation of myoblasts into myotubes (muscle fibers). this will not happen in the body, however these increased myonucei will fuse to exsisting fibers, making them larger.
Bottom Line, the benifits and costs of IGF-1 use are far from known yet.

You might want to start doing some research on hypoglycemia brought on after taking IGF. My son is curently having problems with this right now. Symptoms include dizziness, panic attacks, depression, tremors, feeling close to losing both control and consciousness. One trip to the ER and another to a doctor’s office have resulted in no concrete answers. He has a friend who reported the same symptoms. The friend made 4 trips to the ER because he felt like he was going to either pass out or die. The friend, too, had these symptoms come on after getting off IGF. Two words…..be careful.

In responce to Mom,
This is not a substance to take lightly. This is a very powerful stubstance and affects your insulin levels. You need to keep an eye on your blood sugar levels while on and coming off of IGF1. If not, you could easily go hypo and pass out or feel like you are going to pass out. If the user has not studied this drug and understand how it works i would not recommend using it.

“IGF-I has been identified as a key factor in cancer.”
(Hankinson. The Lancet, vol. 351. May 9, 1998)
The IGF signaling pathway appears to play a crucial role in cancer. (Velcheti V, Govindan R (2006). “Insulin-like growth factor and lung cancer”. Journal of thoracic oncology : official publication of the International Association for the Study of Lung Cancer 1 (7): 607-10)

We continue to see conflicting data all the time on this issue. According to the below data, from the National Cancer Institute, IGF’s have the ability to promote as well as suppress certain types of cancers cells. That is why it is imperative you stay under the supervision of a good hormone doctor.
IGF-I levels in human tissue causes many of the degenerative changes associated with aging. We believe it is aging which is greater catalyst for Cancer. If IGF-1 caused cancer it would run rampant in kids. You don’t really see that. IGF-1 could cause cancer to grow faster; however, it does not give one cancer if it is not already present.

There is plenty of evidence that IGF-1 extends the lives of men.

Does IGF-1 have the same overall body growth results that HGH has, such as bone and organ growth?
June 13th, 2008 at 8:04 am
IF you are a grown man, IGF or HGH does not cause bone or organs to grow at normal doses. You must be under the direct supervision of a good hormone doctor to even consider these peptides. They are really strong.

I am just getting into the IGF-1 reasearch. Is the
IGF-1(the spray)found in stores such as GNC the same product? Doesn’t seem like it from the info I gather. How is that IGF-1 different than what we are talking about in the article?
June 19th, 2008 at 11:45 pm
Travis over the counter hGH and IGF-1 products are bogus. Most of these peptides need to be injected and prescribed by a hormone doctor.
