    Half life of deca

    More specifically Nan Deca. Conflicting info everywhere else. Some say 6 days some say 15 days. I am 99% sure its not 6 days but is it as long as 15 days? And actually a second part to the question- if it is 15 days and I'm dosing 200 2x a week. Doesn't that build up super high before anything starts to clear out. I think you would be on 5th pin totalling 1000mg before the first 100 cleared out. And it would get consistently built up higher each pin.

    Re: Half life of deca

    Hiya Italian-

    Here's a study showing deca DECANOATE (not sure of if you meant npp or deca dec sine they're both nan lol) having a half life of 7-12 days:

    Pharmacokinetic Evaluation of Three Different Intramuscular Doses of Nandrolone Decanoate: Analysis of Serum and Urine Samples in Healthy Men
    Abstract

    The pharmacokinetics of nandrolone in serum and urine were investigated in healthy young men after a single im injection of 50 mg (n = 20), 100 mg (n = 17), or 150 mg (n = 17) nandrolone decanoate. Blood samples were collected before treatment and for up to 32 d after dosing. In addition, in the 50- and 150-mg groups, 24-h urine samples were collected before treatment and on d 1, 7, and 33 after treatment; in the 150-mg group, additional samples were collected after 3 and 6 months. Serum concentrations and the area under the curve of nandrolone increased proportionally with the dose administered. The peak serum concentration ranged from 2.14 ng/ml in the 50-mg group to 4.26 ng/ml in the 100-mg group and 5.16 ng/ml in the 150-mg group. The peak serum concentration was reached after 30 h (50 and 100 mg) and 72 h (150 mg), whereas the terminal half-life was 7–12 d. In urine, pretreatment concentrations of 19-norandrosterone (19-NA) and/or 19-noretiocholanolone (19-NE) were detected in five of 37 subjects (14%). In the 50-mg group, 19-NA and/or 19-NE could be detected at least until 33 d after injection in 16 of 17 subjects (94%). In the 150-mg group, who were presumed to have not previously used nandrolone, nandrolone metabolites could be detected for up to 6 months in eight of 12 subjects (67%) for 19-NE and in 10 of 12 subjects (83%) for 19-NA.

    Now remember too that it matters what oil you use and all that, a la this study:

    I'd say 6-12 days for deca durabolin, though

    HA! Had no idea on the spelling, so put that for the time being, and was going to look it up and go back and fix it. Obviously didn't happen. Yeah Nandrolone Decanoate. Nice find. Good info. Thanks again.
