Omnadren is a four-component testosterone. The four different substances work together in such a timely manner that Omnadren remains in the body for a long time. For this reason many compare Omnadren to Sustanon 250. This comparison, however, is quite poor since, in part, there are large differences between the two compounds. Although both are “four-component testosterones” the individual substances of Omnadren and Sustanon are not completely identical. Both include testosterone phenylpropionate and testosterone propionate; however, the testosterone isocaproate in Sustanon is replaced by testosterone isohexanoate and the testosterone decanoate in Omnadren is replaced by testosterone hexanoate in Sustanon (see also Sustanon).
In bodybuilding and powerlifting Omnadren is exclusively used to build up strength and mass. The term “mass buildup” can be taken quite literally by the reader since the gain is not always the way expected by its user. In most athletes Omnadren leads to quite a rapid and pronounced increase in body weight, which usually goes hand in hand with a strong water retention. This results in watery and puffy muscles. Those who take “Omna” can often be recognized by this extreme water retention. The often-used term in Europe, “Omna skull,” does not come from nowhere but because a fast and well-visible water retention occurs also in the face which is noticeable on checks, on the front of the face, and under the eyes. Some mockingly also talk about a hydrocephalus… The pronounced androgenic component of Omnadren goes hand in hand with a high anabolic effect which manifests itself in a high strength gain characterized by a liquid accumulation in the joints, an increased pump effect, increased appetite, and a possible improved regeneration of the athlete.
