Omnadren 250 is a combination of the 4 separate test esters listed above. Older versions of the drug list the final two esters as ´isohexanoate´ and ´hexanoate.´ However, it should be noted that hexanoate is simply another word for caproate so the drug´s esters have not actually been modified. Most commonly, people will correlate Omnadren 250 with its cousin Sustanon 250, since they are both a blend of 4 test esters. The only difference between the two lies in the last and most concentrated- ester. Whilst Omnadren contains the caproate ester, Sustanon contains the decanoate ester in the same concentration. Really, except for price, there´s no difference& and price-wise, you´re going to be paying ½ as much for Omnadren as you would for Sustanon (or $3-4usd/amp). This is a very nice price, and for that reason, I typically advise people to purchase Omnadren over Sustanon, if their source carries it.
