Dianabol is also capable of interaction with the enzyme aromatase resulting in the possibility of estrogenic side effects. Gynecomastia may become apparent even very early into a cycle, so the user must always ensure that they have the necessary drugs to treat the condition at the earliest possible opportunity. A Selective Estrogen Modulator (SERM) such as Tamoxifen (brand name Nolvadex) is usually used in these instances, perhaps with the addition of an anti-estrogen such as Proviron or Arimidex which will help hinder further estrogenic conversion. (For more information see the article Combating Oestrogens & Progesterone ).
The remaining 3 characters in this field are for the optional input of a Part identity and which allows several Export Declarations to have the same core DUCR . It is this, in combination with the (up to) 35 character UCR which must be unique. An example of Part identity use would be a large consignment covered by a single DUCR but being exported on say 3 vessels over a period of weeks or months. Ideally, the DUCR would use a common identifier in the trader’s records, but each movement of the goods would have a separate CHIEF declaration, using the same DUCR but designated as Part 001, 002 and 003.
