Finally, the life of a steroid-user is not as glamorous as it seems. Steroids are expensive and illegal. They can do jail time if caught, and there are a lot of ancillary drugs and supplements that must also be taken to minimize the damage to their organs or to keep certain hormones in normal ranges (ex: Nolvadex). Their bloodwork (hematocrit, cholesterol profile, etc.) and blood pressure is often atrocious. They battle with sleep apnea and fluctuating moods and sex-drives, and many have trouble performing simple daily task such as wiping their butts or washing their backs. Last, their caloric intake is much higher (and expensive), and it becomes a chore to meet calorie and protein requirements day in and day out. The grass is not always greener on the other side.
the synergy (Atleast in animal studies) is both deca and tren's interaction with igf molecules. nandrolone in rat studies increased igfb3 in all tissue and decreased igfbp4. nand also increases igf-1 but tren is shown to do this to a greater extent (in animals) so with nand decreasing igfbp-4 that means there's less igf-1 binding to this protein and more available to bind to the receptor. igfbp-3 being increased will enhance the half life of igf-1. couple this with the igf-1 increase from tren and you get the synergy....atleast on paper!
