IGF-1 Info

  1. IGF-1 Info

    From Guy at CJM

    IGF1, also known as somatomedin C, is polypeptide hormone about the same size as insulin. It is produced predominantly in the liver in response to growth hormone (GH) release from the pituitary gland. Many of the growth promoting effects of GH are due to its ability to release IGF1 from the liver. The conversion ratio of GH to IGF1 varies greatly in different individuals but most external sources of GH convert around 4-6mcg of IGF per one I.U. of GH. IGF-1 acts on several different tissues to enhance growth. IGF1 belongs in the 'superfamily' of substances known as 'growth factors,' along with epidermal (skin), transforming; platelet derived fibroblast, nerve, and ciliary neurotrophic growth factors. None of the other factors have any bearing on exoskeletal tissue incidentally however These agents all have in common the ability to stimulate cell division, known as mitogenesis, and cell differentiation. Meaning That In the case of IGF1 which does act on muscle tissue it will initiate the growth of new muscle fibers, and subsequently new receptors for testosterone. Users have unanimously concluded that it enhances cycles of steroids significantly. They also seem to be adamant about its ability to reduce fat and improve vascularity a great deal.

    The IGF1 Hype

    There is a considerable amount of hype surrounding IGF1. Every one is blaming the distended bellies of modern Bodybuilders on it. Also the freaky proportions that old bodybuilders that have been around for years are starting to attain. Anti-aging proponents are touting it as the miracle cure for every thing from Parkinson's disease to Alzheimer's. And the medical community has published numerous articles on it for its ability to cause cancer, diabetes and gigantism. While at the same time performing documented experiments on thousands of patients of muscle wasting diseases. And reporting significant turnabouts in there conditions. So what is a guy to think about IGF1 as far as athletic enhancement is concerned? Well first of all you need to know that most experiments conducted with IGF1 do not list the type of IGF used. I have written Dr. Robert Saline of the Swedish rejuvenation institute on several occasions and we have had in-depth discussions on the subject of IGF1 for physical appearance enhancement. He feels it would be unethical to prescribe IGF1 to a bodybuilder to increase muscle mass simply due to the fact that IGF1 has valid applications in the medical community, (Like I could give a rats ass about "ethical"). He can not argue that it is extremely effective as a promoter of muscle growth far beyond what androgens (steroids) alone can offer. Well fortunately in America IGF1 is not a drug (yet) and the FDA has no control over it as of now. This will change in the very near future however, Im absolutely sure of it.

    How to use IGF1

    Assuming that you have acquired legitimate IGF1 (R3) long chain, That's IGF1 with the binding protein added. You should take dosages ranging from 60mcg up to 120mcg per day in divided doses. One injection in the morning and again at bed time. Never exceed 120mcg in one day. IGF1 can cause serious gastrointestinal problems such as tumors intestinal swelling diarrhea and vomiting. Most IGF1 comes in a concentration of 1000mcg per ML or CC so it makes it easy to measure in an insulin syringe. 10 IU on the syringe is 100mcg. Do the math.

    IGF + Insulin

    If you plan on doing IGF1 with Insulin, listen closely IGF1 is not that expensive, sure you can get away with using less by including insulin in the stack, but IGF1 and Insulin together have a pro-insulin effect on your blood sugar balance. It can enhance the chances of a hypoglycemic episode ten fold. I would recommend against it for any one not ABSOLUTLY comfortable with insulin or IGF1.

    Here is how insulin and IGF1 work together. Igfbp3 is the binding protein, which allows IGF1 to remain active in the system for a long enough period of time to really work its magic. IGF1 by nature has a half-life of less than 10 minutes by its self. The molecule was so small it would escape the blood stream very rapidly. This was the reason IGF1 was so "underground". It took very frequent injections at high dosages to achieve even minimal results. Aside from this reconstituting the compound required a degree in biochemistry. This short acting version was the only IGF1 known until recently IGF1 would have been administered in 100 mcg dosages 4-6 times a day. That is a hell of a lot of IGF1. That explains a lot of the distended bellies. Now with R3 long chain IGF1 and the Binding protein IGFBP3 IGF1 will last up to 6 hours in the system. By binding IGF to the IGFBP3 you make the molecule larger and it gets trapped in the blood stream until the protein is broken down and the IGF molecule escapes. You can further its life by combining Insulin with it, although I here its very risky. Insulin prevents the breakdown of IGFBP3 and leaves the IGF1 molecule roaming free in the blood stream for longer periods of time up to 12 hours as insulin levels return to normal IGFBP3 will begin to break down and the IGF1 will escape from its bound protein IGFBP3 again having a half life of less than 10 minutes.

    Insulin should be taken at the normal dosage it is usually administered at minus 10% about 45 minutes prior to the IGF1 infusion. Again let me remind you this can be deadly if you don't know what you are doing. And of course do not use Insulin for the nighttime injection of IGF1 by taking it in the morning you prolong the IGF1's half life to 12 hours and then take a 6 hour injection, you should be fine. Hell if you want to eat a big bowl of rice and drink another 100g of simple carbs 45 minutes before the bed time IGF1 infusion you could spike insulin for at least a few hours of extended IGF1 activity. If your not going to be using insulin in the stack then go ahead and do the same in the morning.

    What users report

    Users of IGF1 have reported various results but all along the same lines, It does not appear to be dramatically less effective in any one individual (at least not to the best of my knowledge). I have a good friend who had to stop taking IGF1 due to stomach illness that was completely unrelated But he to experienced good gains from it for the 2 weeks he was on it, his dosage was 120mcg per day. One hour after the first injection he went to the gym and immediately told me about the uncontrollable pump he got from just one set.

    That would indicate to me that he was experiencing some form of cell volumization. The general consensus on IGF1 seems to be that its benefits are as fallow:

    Increased Pump Pumps are reported to be so severe that workouts are often cut short due to lack of ability to the muscle through the full range of motion...ouch

    Gains retention is increased if IGF is used in a cycle I am not sure why, but IGF1 seems to make gains on a cycle stick with virtually no post cycle loss. Every bodybuilder I've spoken with seems to think this for some reason. Most of them use drugs like Anadrol or Dianabol with it because of the amount of size attained with these drugs. The usual draw back to these drugs is that in most users there is a post cycle "crash" that occurs, so the reasoning is to toss IGF1 into the stack and grow larger faster with out the post cycle crash blues.

    Reverses testicular atrophy

    Testicles if shrunken will return to "full swing" so to speak even in the middle of a cycle. If not shrunken they will not shrink during the cycle. This may explain partially why gains are kept after the cycle.


    Users report feeling drained and tired all day. This seems to be one of the negative side effects to IGF1, it will make you sleep longer and you will require more sleep at night to feel rested for the morning. This is common with high doses of HGH and exhibited in children, whose IGF1 levels are extraordinarily high. A child needs 4 hours more sleep than an adult on average does. This may be directly or indirectly related to IGF1 levels.


    An almost arthritic feeling is commonly associated with high levels of HGH, well IGF1 has the exact same property. IGF1 will cause your hands, fingers and knuckles to ache this is one way you can be sure you got real IGF1.

    IGF-1's Side effects

    Every thing has a down side. To bake a cake ya gotta brake an egg. IGF1 is no exception. The drug used in larger quantity around the 100mcg+ range will cause headaches, occasional nausea and can contribute to low blood sugar or hypoglycemia in some users. Although I have never heard of this first hand I'm sure its true.

    IGF1 will attach its self to the lining of the intestine and cause atrophy of the gut. Every thing IGF1 touches will grow and you have a lot of receptors on the lining of the large intestine and inner wall of the abdominal well. This is what causes the GH gut look. You can easily avoid this by limiting your dosages and cycle lengths. IGF1 cycles should be kept to 4-6 weeks with 4-6 weeks off in-between. IGF-1 is considerably more powerful than HGH and you need to think of it along those lines as far as dosing goes. We all know what to much HGH can do over prolonged periods of usage. The Neanderthal look is definitely not going to win any shows this year. I would recommend 80 mcg a day for 4 weeks at a time you should get good results from that for a while. I don't know if you will need to up the dosage at any point, but I would think in the case of IGF1 it wouldn't matter. If 80mcg doesn't do it for ya, then bump it up to 100 You should definitely feel it at this point If not suspect the IGF1 as being fake. Beyond 120 mcg per day your asking for trouble, This compound demands as much respect as its sister amino Insulin.

    Clinical Facts about IGF-1

    IGF-1 is a polypeptide of 70 amino acids (7650 daltons), and is one of a number of related insulin-like growth factors present in the circulation. The molecule shows approximately 50% sequence homology with proinsulin and has a number of biological activities similar to insulin. IGF-1 is a mediator of longitudinal growth in humans or how tall you are capable of becoming. Serum IGF-1 concentrations are altered by age, nutritional status, body composition, and growth hormone secretion. A single basal IGF-1 level is useful in the assessment of short stature in children and in nutritional support studies of acutely ill patients. For the diagnosis of acromegaly, a single IGF-1 concentration is more reliable than a random hGH measurement (Oppizi, et al., 1986). IGF-1 can be used for the assessment of disease activity in acromegaly (Barkan, et al., 198.

    Almost all (>95%) of serum IGF-1 circulates bound to specific IGF binding proteins (IGFBPs), of which six classes (IGFBPs 1-6) have been identified (Rudd, 1991). BP3 is thought to be the major binding protein of IGF-1.

  2. listen closely IGF1 is not that expensive
    ummm... i felt like bringing this up...

    so what is "not expensive"

    i've seen different prices for IGF-1 R3 and 1mg is around $350 or so... how in the HELL is this not expensive?

  3. Sure more of the weight is kept, since some of that weight is because of your bigger organs and thicker cardiac tissue--not necessarily weight you want.

    "Escape your bloodstream"?

    Haven't heard anyone but bodybuilders use the term "somatomedian C" in a long long time. How's about GH-sulfaction factor for a real old name.

    It's way too expensive and hard to find even if it didn't have those funny sides. Why not just buy a few cycles of something else?

    well , u pay around the same for a gh kit , and i promise the gains from 1 mg of igf-1 will be much more better than from gh . gh is mainly working thro stimulation of igf-1 production , and  u wud rather go with igf-1 site specifically along with insulin use , and this produces more over all igf-1 than gh use leading to better hypertrophy .

    hal, the weight is kept becos of bigger organs ?? i'm sure ure aware igf-1 is used site specifically , and if ure injecting away from the gi track ( which igf-1 has affinity leading to the distention of the gut) , then nothing of this sort is happening .

    well , why not buy a few cycles of something else ?? depends on u , if ure training right and using the right gear , u might never need igf-1 . but if ure saying igf-1 use is worthless , then ure quite wrong .

    hard to find igf-1 ? yes , maybe , but its sold for research purposes and it is available , not very hard to find .

  5. i can find a legit source of IGF1 much easier than any juice thats for sure

  6. I didn't mean it was useless, I just fail to see how it's worth the money for body enhancement. I'd still be concerned about locally injected IGF leaching into the blood stream.
    Raybravo, are you suggesting that the gut distention associated with IGF use is due to mainlining it or IP injections?

  7. whats ip injections ??
    anyway , the gut distention happens like u said when its megadosed for quite a long time , and trust me , me and u are not going to be able to afford that any soon .
    and if ure still concerned about all such small side effects (which are not going to happen) , then dont we have plenty such side effects to worry about from steroids use ?

  8. Ok, so you're saying that the gut distention is due to professional bb'ers not knowing better and shooting too much?
    Shouldn't that alone be enough to keep the rest of us from IGF-I?
    Other enhancers are available if you know where to look that don't have such potentital sides, and their sides are treatable if you know what to ask your dealer for.

  9. u say "other enhancers are available " , such as ?????

  10. IP mean inter-periotineal (SP?)--shots into the gut avoiding the organs

  11. By other enhancers I mean that if a person is to the point where they are considering obtaining IGF-I and shooting a research grade protein, well they are probably able to find a source of test, deca, d-bol...IMHO, they should stick to that. If they are so advanced that they don't think that a "normal" steroid should help them, well then in all honesty, they're probalby not looking at any of the web-boards.

  12. well , trust me , pretty soon u will get to a point where test , dbol and deca are doing nothing for ur lagging parts . and then u will think of igf-1 and pgf-2 .

  13. Well, when test, deca and/or d-bol don't work, you're pretty damn big! If at that point you decide to try the IGFs....hrrm, I still don't see that it's worth it IMHO.

  14. Hey, uhhh guys?? I just posted info for anyone interested in it. It was not meant to be a topic of, if its good or bad. BTW I think good!!


  15. How much?

    Maybe dumb question, but only real dumb one is the one unasked.

    And I have read all the posts on this I could find and have not seen answer...

    How much is in a R3 IGF-1 1mg kit?

    I see average dosage per day is 40mcg to 80mcg, so how let's say you did 50mcg a day.

    How many days is in a one 1mg kit?

    p.s. I never was good a metrics....

    Was looking at possibly doing this with my PCT.

  16. 1mg = 1000mcg

    1000mcg / 50mcg = 20 days


    And whether it's worth it or not.. is a personal thing.. If you can afford it, it's worth it.. if you can't it's not. 350 for 1mg is alot more then I paid though...

    Thanks Poobah, and I see $150 at going rate...
