Omnadren 250 is an oil-based injectable combined of four testosterones (30 mg testosterone propionate, 60 mg testosterone phenylpropionate, 60 mg testosterone isocaproate, 100 mg testosterone decanoate). The mixture of the testosterones are time-released to provide an immediate effect while still remaining active in the body for up to a month. As with other testosterones, Omnadren is an androgenic steroid with a pronounced anabolic effect.
Therefore, athletes commonly use Omnadren to put on mass and size while increasing strength. However, unlike other testosterone compounds such as Cypionate and Enanthate, the use of Omnadren leads to less water retention and estrogenic side effects. This characteristic is extremely beneficial to bodybuilders who suffer from gynecomastia yet still seek the powerful anabolic effect of an injectable testosterone. The decreased water retention also makes Omnadren a desirable steroid for bodybuilders and athletes interested in cutting up or building a solid foundation of quality mass.
Dosages of Omnadren range from 250 mg every other week, up to 2000 mg or more per week. These dosages seem to be the extremes. A more common dosage would range from 250 mg to 1000 mg per week. Although Omnadren remains active for up to a month, injections should be taken at least once a week to keep testosterone levels stable. A steroid novice can expect to gain about 20 pounds within a couple of months by using only 250 mg of Omnadren a week. More advanced athletes will obviously need higher dosages to obtain the desired effect. Omnadren is a fairly safe steroid, but in high dosages, some athletes may experience side effects due to an elevated estrogen level. With dosages exceeding 1000 mg a week, it is probably wise to use an antiestrogen such as Nolvadex (tamoxifen citrate) or Proviron (mesterolone). The use of Omnadren will suppress natural testosterone production, so the use of HCG (human chorionic gonadotropin) or Clomid (clomiphene citrate) may be appropriate at the end of a cycle. Omnadren 250 is a good base steroid to use in a stack. The most popular way to use Omnadren is on a weight gaining cycle in a stack with an oral anabolic like Anavar or Winstrol.
250 - 1500 mg/week
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.
