UPDATED: As of fall 2000, the formula
for Omnadren 250 is identical to the formula for
Sustanon 250.
by Bill Roberts - This preparation is
quite similar to Sustanon,
and is different only in that 100 mg/mL of it (of
250 mg/mL total) is testosterone hexanoate instead
of the testosterone decanoate used in Sustanon.
For this reason, Omnadren has a shorter half life,
and will give a faster initial increase in blood
level. This accounts for the claim of increased
water retention and increased side effects, since
levels, at first, are higher for the same dosage.
The claim that Omnadren has a duration effect
of "a good 2-3 weeks" is somewhat misleading since
the half life of the longest lived component is
only about 5 days. There is of course some effect
2 or 3 weeks after injection, but relatively little.
The hexanoate ester is quite similar to the well
known enanthate ester, but is shorter by one carbon.
The isohexanoate ester in Omnadren is the same,
only named differently, as the isocaproate ester
in Sustanon. Thus, the hexanoate vs. decanoate difference
is the only difference in the mixture of esters.
