    Deca's Effect on HPTA - Read Please, but is true or not?






    Deca's Effect on HPTA

    Q: In your first year sample cycles section for the male (In Chemical Muscle Enhancement), the cycle outlined for weeks 1-4 is 200 mg deca per week. now that much deca per week is less anabolic than what the natural test (HPTA) can produce (test being stronger than nandrolone mg to mg) . and because of the ester attached to nandrolone , 4 weeks long is hardly enough for blood levels to reach a constant level .

    Also , how is deca easy on the HTPA , you go ahead and say post cycle meds are not necessary as deca is easy on the HTPA which we from multiple examples know is so not true , cases of testicular shrinkage , limp dick etc are so much reported normally on a deca only cycle sir . Can you please explain your logic behind this ??

    You also mention cytomel increased cellular androgen receptor clearing (pg 181 and 182 in the book). How true is this sir ??

    Looking forward to your answers to these questions sir , thanks .

    A: Nandrolone is actually more anabolic but less androgenic than testosterone and as such allows an increase in muscle protein synthesis in excess of that seen with testosterone. So the next question should obviously be "why then does testosterone deliver more weight gain then nandrolone?" Since nandrolone is about 80% less affected by aromatase when compared to testosterone, it should seem obvious that the lack of GLUT-4 (increased muscle glycogen synthesis) activity will also result in a decrease in intracellular content but not cellular wall protein synthesis. Since we are speaking of post-cycle retention as well here we would be in error if we included the on-cycle increase in the body’s water table from estrogen/aldosterone resulting from the higher aromatizing testosterone in our comparison.

    When we employ brief cycles of 4 weeks, a 200mg dosage of nandrolone decanoate would have an additive effect to the endogenous (naturally produced in the body) testosterone for the first 3 weeks. For a novice this accounts for about twice the normal rate of anabolism possible if diet is correct (anabolism is not potentiated unless the macronutrient environment is as well). Many do not realize that the body actually produces about 150mg of testosterone weekly. It circulates about 50mg of testosterone weekly, but it produces about 150mg. Much testosterone is lost to enzymic conversion to 4-androstenediols and various intermediates of DHT. So in essence we are creating a close hormone environment comparison to that realized at about week 6 of a 200mg each testosterone cypionate and nandrolone decanoate protocol.

    The issue of nandrolone having such profound progesterone effects is a bit overplayed for some reason that I cannot grasp. For periods of only 4 weeks and at dosages of up to 400mg weekly, the actual progestin effect is not really of concern. Though it should be noted that the HPTA will not supply adequate testosterone (and subsequently DHT) to support a healthy libido beyond that point. And the estrogenic value is far less for nor-estrogens as a whole. As example is the effect upon HPTA function. LH and FSH are the determining factors for HPTA function itself. For this reason we can determine the degree of HPTA function inhibition that occurs as a result of the administration of different AAS. Novices that had normal LH/FSH levels prior to nandrolone administration showed an average decrease in LH/FSH of only about 33% at day 21 and 39% at day 28. Additionally at day 42 (2 weeks after discontinuance) LH/FSH level were only suppress an average of 21% thus showing a positive rebound effect. In comparison testosterone administration for the same period results in an addition decrease in LH/FSH of about 12% (bodyfat levels can have a profound effect upon this).

    Normal

    Male FSH reference range: 1.4-18.1 mIU/ml

    Male LH reference range: 1.59.3 mIU/ml

    is true or not, I can follow as he says, are unlikely to inhibit HPTA with 200mg of Deca for 4 weeks?

    We can see from the chart below that a single 100mg injection of Deca caused a total (100%) reduction of natural testosterone levels, and it took roughly a month to return those testosterone levels to baseline! All from 100mgs of Deca!



    Figure 3
    Time course of plasma testosterone concentrations in 23 healthy men over 32 days after i.m. injection of 100 mg of nandrolone phenylpropionate in 4 ml of arachis oil vehicle into the gluteal muscle (group 1) (♦) or injection of 100 mg of nandrolone decanoate into the gluteal muscle in 4 ml of arachis oil vehicle (group 2) (○), into the gluteal muscle in 1 ml of arachis oil vehicle (group 3) (•) or into the deltoid muscle in 1 ml of arachis oil vehicle (group 4) (▪). Results expressed as mean and S.E.M., unless the S.E. is smaller than the symbol.
