  1. IGF-1 for tendinitis?

    We had a thread recently where GH given to horses resulted in weaker tendons that were less stiff. The authors concluded GH is probably not a good treatment for tendinitis.

     

    http://www.cuttingedgemuscle.com/Fo...hp?threadid=438

     

    In this study they injected IGF-1 directly into the tendon and got good results, although the tendon was stiffer than the controls (just the opposite from the GH study; I wonder if this effect is real or the result of some "flaw" in one of the studies?).

    Flexor tendinitis is a common and debilitating injury of elite and recreational athletes. Healing may be improved through intratendinous injection of insulin-like growth factor-I (IGF-I), which has been shown in vitro to stimulate mitogenesis and enhance tendon matrix production. This study investigated the effects of intratendinous injection of IGF-I on tendon healing in an equine model of flexor tendinitis. Collagenase-induced lesions were created in the tensile region of theflexor digitorum superficialis tendon of both forelimbs of eight horses. Treated tendons were injected with 2 microg rhlGF-I intralesionally every other day for 10 injections, while controls received 0.9% NaCl. Tendon fiber deposition and organization were evaluated serially using ultrasonography throughout the 8 week trial period. Following euthanasia, the tendons were harvested and DNA, hydroxyproline, and glycosaminoglycan content determined, mechanical strength and stiffness evaluated, gene expression and spatial arrangement of collagen types I and III assessed by northern blot and in situ hybridization, and tendon fiber architecture assessed by polarized light microscopy. Local soft tissue swelling was reduced in the IGF-I treated limbs. Similarly, lesion size in IGF-I treated tendons was smaller 3 and 4 weeks after initiation of treatment. Cell proliferation and collagen content of the IGF-I treated tendons were increased compared to controls. Mechanically, IGF-I treated tendons showed a trend toward increased stiffness compared to saline treated controls. Considered together with the decreased soft tissue swelling and improved sonographic healing, these data support the potential use of intralesional IGF-I for treatment of debilitating tendon injuries.

  2. More bad news about lifting

    There have been at least a couple of posts here about lifting leading to cardiomyopathy. It seems that lifting also stiffens the arteries (a decrease in arterial compliance), making a person more prone to develop hypertension and vascular disease.

    Greater age-related reductions in central arterial compliance in resistance-trained men.

    Reductions in the compliance of central arteries exert a number of adverse effects on systemic cardiovascular function and disease risk. Using the cross-sectional study design, we determined the relation between chronic resistance training and carotid arterial compliance. A total of 62 healthy normotensive men, 20 to 39 years of age (young) and 40 to 60 years of age (middle-aged), who were either sedentary or resistance-trained, were studied. In both activity groups, carotid arterial compliance (simultaneous ultrasound and applanation tonometry) was lower (P<0.05) in the middle-aged compared with the young men. There was no significant difference between young sedentary and resistance-trained men. In the middle-aged group, carotid arterial compliance in the resistance-trained men was approximately 30% lower (P<0.01) than their sedentary peers. Femoral artery compliance and arm pulse wave velocity (measures of peripheral artery stiffness) were not different among any groups. Left ventricular hypertrophy index (echocardiography) was greater (P<0.05) in resistance-trained compared with sedentary men and was associated with carotid arterial compliance (r=-0.35; P<0.01). We concluded that (1) resistance training is associated with the smaller central arterial compliance in healthy middle-aged men; (2) age-related reductions in arterial compliance was greater in resistance-trained men than in sedentary men; and (3) the lower arterial compliance in the resistance-trained men is associated with left ventricular hypertrophy. In marked contrast to the beneficial effect of regular aerobic exercise, the present findings are not consistent with the idea that resistance training exerts beneficial influences on arterial wall buffering functions

  3. Aromasin best Anti-E! Check it out...

     

    Quoted from "Zyglamail" from EF:

    "Anastrozole is the same as liquidex. femara is slightly better as an anti-e but both seem to have more of a negative impact on lipid profiles than aromasin which is much more powerfull than both of them."

     

    Quoted from "CandianBro" From EF:

    "There can be NO DEBATE!

     

    Aromasin is the king of all anti-e's!

     

    After using 2mg/day of Arimidex during a 1000mg/week

    Test cycle and STILL getting quite a bit of water weight as well as slight gyno, I decided to try Aromasin.

     

    Well, needless to say, after shooting 1gram + of test per week and taking ONE 25mg Aromasin per day, I literally had ZERO water bloat and gyno........ZERO!!!

     

    Aromasin is simply INCREDILE

     

    I think the reason Arimidex is much more popular is because it is much readily available as there are SEVERAL generic and undergorund versions.

     

    However, it one has access to real Aromasin (Pharmacia), then there should be no choice between the two.

     

    I'm sure those that have used BOTH will concur."

     

    Quoted from "DrJMW" from EF:

    Interesting Facts about Aromasin (post #1)

     

    1. It is an irreversible, steroidal aromatase inactivator

     

    2. Structurally related to androstenedione

     

    3. Significantly lowers estrogen and has no detectable effect on adrenal biosynthesis of corticosteroids or aldosterone

     

    4. Aromasin 25mg daily reduced whole body aromitization by 98%

     

    5. Has a slight affinity for the androgen receptor (.28% relative to dihydrotestosterone)

     

    6. The binding affinity of its 17-dihydrometabolite for the androgen receptor is 100-times that of the parent compound.

     

    7. Daily doses had no effect on levels of testosterone, androstenedione, dehydroepiandrosterone, or 17-hydroxyprogesterone.

     

    8. A dose-dependent decrease in sex hormone binding globulin (SHBG) has been observed.

     

    9. Slight, non-dose dependent increases in serum LH and FSH have been observed.

     

    These are the links i quoted people from. I don't take any credit for this post. I didn't write any of it, all i did is research it and post it to make it easier for everyone to read in a condensed post. And you can go back and read the threads I copied them from.

  4. Drug Side Effects - Gynecomastia Male Breast Enlargement

     

    There are many possible reasons for male breast growth. If caused by a medical problem, this should be corrected first. Such issues can be investigated by your internist or an endocrinologist. In most cases there is no known cause. A complete discussion of the many possible causes for gynecomastia is beyond the scope of this introduction.

     

    These drugs (according to the Physician Desk Reference) can cause gynecomastia as a side effect. The risks are generally very low for male breast enlargement from these medications, but breasts in men can be a cause for embarrassment. Some medications may be important for your other medical problems.

  5. Before you decide that blocking progesterone is the solution to gyno, consider a few things. There is not one case of progesterone induced gyno in the medical literature EXCEPT in those cases where strong synthetic progestins, like medroxyprogesterone, were administered. In these cases the gyno is due to suppression of LH and testosterone by the progestin, NOT by a direct effect on breast tissue. On a cycle your LH is already suppressed by the AAS anyway.

     

    Breasts have two components: alveoli and ducts. The alveoli are what secrete milk; they drain into ducts. Gynecomastia is the result of ductal hyperplasia, not alveolar hyperplasia. Estrogen stimulates the ductal tissue, while progesterone stimulates the alveoli. Alveolar hyperplasia does not contribute to gyno. If you want to read more on breast development, I suggest visiting this site:

     

    http://www.endotext.org/male/male14/male14.htm

     

    In various tissues throughout the body, including cultured neoplastic breast tissue, progestins downregulate the estrogen receptor (1). Progesterone receptor blockers like RU-486 upregulate the estrogen receptor (1). This is consistent with the fact that RU-486 CAUSES gyno in patients in whom it is used to treat Cushing's disease and meningiomas (2).

     

    Progestins are also anti-estrogenic in that they induce the enzyme 17-hydroxysteroid dehydrogenase, which catalyzes the oxidation of estradiol to the less potent estrone. Progestins also induce estrogen sulfotransferase, the enzyme which catalyzes the sulfation and inactivation of estrogens.

     

    So do progestins contribute to gyno, and if yes, how so? If you visit the link above you will see that progestins increase IGF-1 levels. As that article indicated, IGF-1 is essential to the the development of mammary tissue. This is also how it is believed that progestins in HRT or oral contraceptives contribute to breast cancer: by increasing IGF-1 levels. But as bodybuilders we are always trying to maximize IGF-1. Hence the futility of trying to lower IGF-1 by blocking progestins. The other anabolics we use will elevate (hopefully) IGF-1, while blocking the progesterone receptor will only increase the levels and activity of estrogen by the mechanisms outlined above.

     

    Two drugs have shown the greatest efficacy in treating gyno: Nolvadex, and Raloxifene, another SERM. Nolvadex has the longest track record, but a recent trial with Raloxifene showed it to be superior to Nolvadex. With these drugs you attack the problem at its source: the estrogen receptor. You get the added benefit of lowering IGF-1. Not a good thing for making gains, but important for treating gyno.

  6. In addition to elevated IGF-1, lowered DHT levels resulting from endogenous testosterone suppression may contribute to gyno from non aromatizing steroids. Gyno is a reported side effect from finasteride use. Some have attributed this to elevated estrogen levels due to the fact that there is more testosterone to be aromatized, since less test is being converted to DHT. Other researches think that DHT has a direct antiestrogenic effect on breast tissue.

     

    Studies have shown that DHT can actually block estrogen from binding to the estrogen receptor in mammary tissue (1). DHT also is an aromatase inhibitor (2). Even more interesting is the fact that transdermal DHT cream has been used successfully to treat gyno (3).

     

    It may be that the estrogen/DHT ratio is more important to the development of gyno than the estrogen/testosterone ratio.

  7. For Those who wonder How Steroids Work....Technically Speaking

    This is a breakdown of the technical effects of anabolics within the human body. Should my MU bros have anything to add, please feel free. The anabolic effects of the steroids are elicited by the action of the steroids on androgen receptors in muscle tissue. The steroid binds to the receptor and is carried to the nucleus of the cell where it tells the DNA in the cell to transcribe the steroid’s message onto messenger RNA (mRNA). The mRNA then delivers its message to the muscle cells and this causes a response in the cells that results in increased protein synthesis, which causes hypertrophy (growth) of the cells and the muscle tissue that the cells make up.

    The different molecular configurations of the various anabolic steroids cause significantly different cellular responses, and even a subtle change of one atom can elicit a unique response for a specific steroid. That is why each steroid has distinct characteristics that make it more appropriate for specific therapeutic uses.

     

    It should also be noted that anabolic steroids, in general, are hematopoietic (blood building) agents; they increase hemoglobin production and hematocrit.

     

     

    What are your thoughts or additions.
