Chemical athletes who want to use nandrolone to build up their muscle mass are best off choosing a preparation with:
- the longest ester possible
- the highest concentration possible
- injecting it in their gluteus muscle instead of in their shoulders.
The first group were given an injection of 100 mg nandrolone phenylpropionate in their buttock. Phenylpropionate is an ester that does not remain in the blood as long as decanoate. The 100 mg was in an ampoule of 4ml groundnut oil.
The second group got the same kind of injection, but containing nandrolone decanoate, the steroid in Deca-Durabolin
The third group also got an injection containing 100 mg nandrolone decanoate in the buttocks, but this time the nandrolone was concentrated in 1 ml groundnut oil.
And finally, the fourth group were injected with 100 mg nandrolone decanoate, dissolved in 1 ml groundnut oil, in the shoulder muscle.
Nandrolone phenylpropionate gives a rapid peak in the blood, but the peak subsides after 4-5 days. Nandrolone decanoate doesn’t cause a peak, but remains present for much longer in the blood.
More nandrolone enters the blood if you inject it in a more concentrated form: 1 ml instead of 4 ml.
Injecting into the buttocks results in more nandrolone in the blood than injecting into the shoulders.
