What the freak!! Igf side effects.
What is going on here? I have been taking 20 mcg of IGF ED for the last month. Having great results with healing my shoulder. However I have noticed the past two weeks my hair is falling out. Its to the point that I am cutting my cycle short. What is the deal here. Did I get bunk stuff? Not to my knowledge does IGF have any type of side effects like that. What do you guys think?

I have not come across any negative side effects of IGF-1 aside from it speeding up the growth of tumors and possible organ growth issues.
Did you get a COA with your IGF-1?

That is hella weird. Have your balls gotten noticeably bigger?
05-26-2008, 09:27 AM
wtf? i do have a friend that got alopecia whilst using T3 but not igf-1.
if anything you would expect faster hair growth, I certainly get it while on igf.
in studies where finestride was used, patients showed increased IGF-1 expression in hair follicles and some hair regrowth.
The expression of insulin-like growth factor 1 in follicular dermal papillae correlates with therapeutic efficacy of finasteride in androgenetic alopecia
maybe the exogenous igf-1 you are taking is somehow reducing endogenous expression in your body and causing hairloss? thats all I can think of.

Now the question...did you recently run anything else or are you stacking it?
Predisposed to MPB(male pattern baldness)
think of everything.

I got faster hair growth (I am already thinning), but what's there is growing VERY fast, Like NEED a haircut every 4 weeks instead of 6. Haven't had an issue with it falling out faster while on it.
Like MT mentioned, anything else you are on?

Yes, another study excerpt on Growth Faactors and Hair Growth as it pertains to IGF-1:
Given this info, I do not beleive IGF-1 is responsible for the hairloss as it would be putting your follicles into a higher anagen phase. However, it may not be unreasonable that lower IGF, in post IGF cycle could possibly cause the ratio if TGF to IGF to be higher and put you in greater catagen phase which may lead to a greater ratio of shed hairs to newley grown hairs... Just speculating from the info at hand...In humans, each hair follicle goes through repeated cyclical periods of growth including an active growth stage (anagen), which can persist for approximately 2 to 6 years; a transition phase (catagen), which lasts for only a week or two; and a resting period (telogen), which lasts 3 to 4 months. The hair is shed at the end of the telogen phase, and a new hair is grown as the cycle repeats. In the human scalp, which contains approximately 100,000 hair follicles, normally about 86% are in anagen, 1% are in catagen and 13% are in telogen. Therefore, in a normal human adult, approximately 100 hairs are shed from the scalp per day.
There is no single hair growth factor. Hair growth is an interaction between several different cytokines, however, two cytokines stand out from the rest in terms of importance; these are IGF-1 and TGF-BETA. IGF-1 maintains hair follicles in the anagen phase. The follicles enter catagen if IGF-1 is absent. IGF-1 and IGF-1-R gene expression declines. TGF-BETA triggers the catagen phase. It is a potent inhibitor of hair growth in vitro. Relaxin increases IGF-1 and decreases TGF-BETA therefore it has the desired effect on hair growth and prevention of hair loss

IGF doesn't cause hair loss it helps stop hair loss if anything. I've run 4 cycles of IGF and it has never shed hair from the top of my head where as AAS does. Your probably just prone to MPB and thats what is happening. It has nothing to do with the IGF.
05-28-2008, 12:46 AM
Thanks for all the info guys!!!!!
The only thing different besides vitamins is recreate. I started taking both about the same time. I have since stopped everything and am going to stay off for a few weeks. See what happens. I have been off two days and have already noticed a decrease in the little hairs falling out. I have never been predisposed to hair loss. I have freaky thick hair to be honest. There has been some stress but not really anything out of the ordinary.
If I was just losing hair that would be one thing but I have never heard of one day having normal not falling out hair and the next falling out all over the place kindof hair.....
05-28-2008, 12:54 AM
just a comment on your closing sentence. my friend George had the thickest hair you can imagine. then his started falling out everywhere, in the end he lost all the hair and follicles from everywhere including his face and body.
he had used AAS many times and never lost a hair. that one time he was running T3 and igf. we thought the T3 somehow caused it, now im wondering if there are a small minority of people that will lose hair on igf.
05-28-2008, 07:20 AM
Ha ha ha everywhere from his face and body... So now he is completely hairless?!?! That sounds pretty much horrible. Well lets all say a quick little prayer that that is not the case in my situation.

Who knows if messing with T3 and thyroid homeostasis could possibly exacerbate an underlying Thyroid condition in such a case. There definitely seems to be a pattern which links thyroid function and Alopecia Universalis, so it may not be unlikely that T3 abuse could have had some influence.
Also, I have found new info in a study linking increases of IGF-1 to male vertex pattern balding. I was quite surprised by this find given the role of IGF on the hair growth stages, but none the less:
I am wondering if downregulation of IGF-1 receptor expression in the hair follicle could be decreasing the IGF-1 effect on the anagen phase of hair growth as per the previous study info I posted? Seems plausible. Who, knows. The body is such a complex machine, its just amazing.Hormones and hair patterning in men: a role for insulin-like growth factor 1?
Signorello LB, Wuu J, Hsieh C, Tzonou A, Trichopoulos D, Mantzoros CS.
Department of Epidemiology and Harvard Center for Cancer Prevention, Harvard School of Public Health, Boston, Massachusetts 02115, USA.
BACKGROUND: Androgens are important in hair growth and patterning, whereas growth hormone substitution enhances their effect in growth hormone-deficient men. No previous study has jointly evaluated the function of sex steroids, sex hormone-binding globulin (SHBG), and insulin-like growth factor (IGF-1) in determining hair patterning in men. OBJECTIVE: We assessed the relationship between circulating hormone measurements and both head and chest hair patterning in a sample of elderly men. METHODS: Fifty-one apparently healthy men older than 65 years of age were studied cross-sectionally. Head and chest hair patterning was assessed by a trained interviewer. Morning blood samples from all subjects were used for measurements of testosterone, estradiol, dehydroepiandrosterone sulfate, SHBG, and IGF-1. RESULTS: Results were obtained from logistic regression models, adjusting simultaneously for all the measured hormones and age. Men with higher levels of testosterone were more likely to have vertex baldness (odds ratio [OR] = 2.5, 95% confidence interval [CI: 0.9 to 7.8] per 194 ng/dL increment of testosterone). In addition, for each 59 ng/mL increase in IGF-1, the odds of having vertex baldness doubled (95% CI [1.0 to 4.6]). Those who were found to have higher circulating levels of SHBG were less likely to have dense hair on their chest (OR = 0.4, 95% CI [0.1 to 0.9] per 24 nmol/L increment in SHBG]). CONCLUSION: Testosterone, SHBG, and IGF-1 may be important in determining hair patterning in men.

I like this line in the abstract "Androgens are important in hair growth and patterning, whereas growth hormone substitution enhances their effect in growth hormone-deficient men." Makes me want to look into this topic a bit more...

Here is an interesting few lines from studies that mention T3's positive & negative effects on hair growth...which leads to "hair regrowth" applications of novel peptides. There may be a "research chemical" type solution to your friend's alopecia problem. The discussion section from the study is interesting.
ABSTRACT 1 (snippet):
Previously, we demonstrated stimulation of epidermal proliferation and hair growth in triiodothyronine (T(3)) treated mice. To distinguish skin effects of directly applied T(3) from those of systemic hyperthyroidism, we treated CD-1 mice with either intraperitoneally (IP) or topically administered T(3)....
T(3) stimulated proliferation in a dose-dependent, biphasic pattern with the peak at 0.5 nM T(3) (84 +/- 30%, p < 0.05). Paradoxically, T(3) inhibited proliferation of keratinocytes cocultured with fibroblasts, the nadir at 0.1 nM T(3) (34% +/- 4%, p < 0.001). These studies are the first describing divergent effects of IP and topically administered thyroid hormone. The data suggest that while T(3) stimulated keratinocyte proliferation, T(3) also stimulated proliferation inhibitory factor(s) from skin fibroblasts. - Thyroid hormone action on skin: diverging effects of topical versus intraperitoneal administration, Safer JD...

Human skin produces parathyroid hormone related peptide. This peptide is a potent inhibitor of epidermal cell growth. - Topical PTH (1-34) is a novel, safe and effective treatment for psoriasis: a randomized self-controlled trial and an open trial, Holick MF...Br J Dermatol. 2003 Aug;149(2):370-6
STUDY FULL DISCUSSION:
A Topical Parathyroid Hormone/Parathyroid Hormone-Related Peptide Receptor Antagonist Stimulates Hair Growth in Mice,Joshua D. Safer...Endocrinology 2006 Vol. 148, No. 3 1167-1170
Although the physiological role of PTHrP in the skin is not well understood, mounting evidence suggests that this peptide plays an important role in epidermal proliferation and differentiation (4, 5, 6). The PTH/PTHrP receptor agonist, PTH 1–34, inhibited epidermal proliferation in cultured keratinocytes and SKH-1 hairless mice (7). The PTH/PTHrP receptor antagonist, PTH (7–34), reversed the agonist’s antiproliferative effect in vitro. In mice, ip PTH (7–34) stimulated 3H-thymidine incorporation into epidermis in a dose-dependent manner, increased visible hair number, increased hair length, and advanced telogen hair follicles into anagen (6, 8).
The current project was undertaken to determine whether we could deliver PTH (7–34) topically and achieve hair growth stimulation in that fashion.
One of the biggest hurdles in developing peptides for the treatment of hair growth disorders is that there has been no effective method of delivering them topically. In the current study, we formulated PTH (7–34) in a novel liposome cream, which dramatically stimulated hair growth. This represents the first demonstration that a topical peptide preparation can effectively stimulate hair growth.
PTHrP has been implicated as a possible chalone, the hypothesized but elusive hair growth inhibitor that gradually accumulates during anagen and moves the follicle to catagen when present in sufficient concentrations (6, 12) A putative mechanism for PTH (7–34) action is competitive inhibition of the PTHrP antiproliferative and prodifferentiating effects (8).
A unique aspect of skin, is the possibility to directly target it via topical treatment. Our group mixed the PTH/PTHrP receptor agonist, PTH (1–34), into Novasome A and applied the compound topically to humans (13). The antiproliferative properties of PTH (1–34) resulted in successful treatment of the hyperproliferative skin disorder, psoriasis. Whether increased epidermal proliferation caused by PTH (7–34) could exacerbate hyperproliferative skin disease, like psoriasis, remains a topic for future study.
Although the reported study was done with female mice, similar experiments have been done with male mice. The results were the same, consistent with the cutaneous effects of PTH (7–34) being similar in both sexes.
SKH-1 hairless mice were chosen for the study because they provide a background on which changes in hair growth are well discerned. SKH-1 mice lose all external hair in their first hair cycle after birth. Their complete hair loss is related to a mutation in the hairless gene (hr). Although SKH-1 mice appear to have complete hair loss, close inspection reveals that a small number of their hair follicle appear normal histologically.
The SKH-1 mouse model was chosen in part because they are amenable to close visual inspection without shaving or depilating. The avoidance of hair removal procedures removed a potential source of skin injury from our study. In addition, it was straightforward to inspect the mice and confirm the absence of inflammation or injury. In that way, we could attribute the results to anagen and not inflammation.
Endocrinologists see both men and women with alopecia that may be associated with gonadal hormone deficiencies. There are few options available for treatment. Our current study is the first to report the hair stimulating effect of a PTH/PTHrP receptor antagonist topically applied to skin in vivo. Thus, we introduce a novel paradigm to develop topical PTH analogs for treating disorders of hair growth.

PS- Great study info you have contributed again as well as awsome cliff notes for us all (in a different thread well).
As soon as I spread some more reps I'll be comin around to ya!
05-28-2008, 02:57 PM
Long story short you were spot on in your CJC assessment...but the interesting thing the studies show is that synergy is created when you combine GHRH (or longer-lasting analog) and a GHS.
Thanks for the Reps comment but I think I'd really rather have a bag of Doritos...must be the GHRP-6 talking.

Ya Papa, this is the direction I was about to head in
If the IGF and/or injection protocol was not completely sterile, could be possible... Also allergic reactions can cause your lymph nodes to become swollen as well, so you could evaluate based on this as well. You could be allergic to the benzyl alcohol in BW (if using that for dilution)or something in the IGF mix (bulking agent,etc). Too many variables, but you could cancel some out and see if it is the issue. Have you (OP) had any issues with any other peptides (if used)? Have you had this issue with other IGF from different sources? Depending on the answers you could try using a different dilutant like NaCL .9% instead of BW, or try a different vendor for IGF. Not sure this applies to you, but your can use this process to narrow things dow if in fact it is an allergic reaction.
