    Test E / Cyp injects

    Say one wanted to take 500mg of Test E or Cyp a week... Why wouldnt you shoot it all at once, for the full dose instead of 2 smaller dosages. Wouldnt the test levels be suffciently high for atleast 7 days until next inject? Plus you would get a ****load of test at once, and it would take twice as long to fall back down to normal levels... the question is.. what are hte pros and cons of doing injection of 500mg once a week compared to 250mg twice a week??

    You are absolutely correct on shooting Test E all at once, however the cyp would be better ED or EOD. The reason is the half life of the ester. Test E has a 15 day half life and cyp has a 10 to 12 day half life so when looking at injection frequency that should be your determining factor. You could do a higher level of cyp but twice a week whereas you would want to do one injection of Test E per week. Your thinking was right on track but maybe needed just a few more pieces of the puzzle to complete the equation.

    Just fyi here is a list of half lives.

    Oral steroids Drug Active half-life
    Anadrol / Anapolan50 (oxymetholone) 8 to 9 hours
    Anavar (oxandrolone) 9 hours
    Dianabol (methandrostenolone , methandienone) 4.5 to 6 hours
    Methyltestosterone 4 days
    Winstrol (stanozolol )
    (tablets or depot taken orally) 9 hours



    Depot steroids Drug Active half-life
    Deca -durabolin (Nandrolone decanate) 15 days
    Equipoise 14 days
    Finaject (trenbolone acetate) 3 days
    Primobolan (methenolone enanthate ) 10.5 days
    Sustanon or Omnadren 15 to 18 days
    Testosterone Cypionate 12 days
    Testosterone Enanthate 10.5 days
    Testosterone Propionate 4.5 days
    Testosterone Suspension 1 day
    * Winstrol (stanozolol) 1 day


    *Winstrol depot does not actually possess a classical half-life because it is un-esterified. Instead, the microcrystals dissolve slowly. Once they have all dissolved levels of the drug fall very rapidly. It is still an important consideration, and we have included it with a half-life of one day.


    Steroid esters Drug Active half-life
    Formate 1.5 days
    Acetate 3 days
    Propionate 4.5 days
    Phenylpropionate 4.5 days
    Butyrate 6 days
    Valerate 7.5 days
    Hexanoate 9 days
    Caproate 9 days
    Isocaproate 9 days
    Heptanoate 10.5 days
    Enanthate 10.5 days
    Octanoate 12 days
    Cypionate 12 days
    Nonanoate 13.5 days
    Decanoate 15 days
    Undecanoate 16.5 days



    Ancillaries Drug Active half-life
    Arimidex 3 days
    Clenbuterol 1.5 days
    Clomid 5 days
    Cytadren 6 hours
    Ephedrine 6 hours
    T3 10 hours

    Great, but to take it one step further.. what are the pros of shooting the Test E once a week @ 500 rather than shooting it at 250mg twice a week... All these talks of keeping levels stable etc... pros/cons?
    My stats are 6'1'' 254 lbs... 11-13%BF
    (Also to cut260: what are your thoughts on sust 250.. you like? how frequent would you inject and how many mgs a week in your opinion?)

    Steroid esters Drug Active half-life
    Enanthate 10.5 days
    Cypionate 12 days

    Hey bro, you kinda contradicted yourself there, enanthate has a half life of about 10 days. Did you mean decanoate by chance?

    I'm a little confused on this logic too, and I'm sure the 15 days was supposed to be 10.5

    Cyp would actually be better than enanthate for once a week injections. It's half-life is longer, not shorter.

    He lists the correct ester half-lives later in the post - and he seems like he knows his basic sh!t, so I figured it was a typo.

    I am definitely confused about how a longer ester needs to be shot more frequently than a shorter ester.
