HI-TECH PHARMACEUTICALS DECABOLIN Hi-Tech Pharma claims DecaBolin is an orally active supplement that offers the only legal Nandrolone precursor on the market. Because DecaBolin converts to Nandrolone and believe it or not, is better than testosterone for building muscle mass. While another possible perk of DecaBolin is that it is has fewer side effects than …
Anabolic steroids, widely used to increase skeletal muscle (SM) mass and improve physical performance. Some dietary supplements also include potent steroid precursors or active steroid analogs nandrolone. Our previous study reported the anabolic steroid effects on SM in a castrated guinea pig model.
SM measured using a highly quantitative magnetic resonance imaging (MRI) protocol. The aim of the current study was to apply this animal model and in vivo MRI protocol. Evaluate the growth effects of four widely used over-the-counter testosterone and nandrolone precursors. 4-androstene-3 17-dione (androstenedione), 4-androstene-3beta 17beta-diol (4-androsdiol), 19-nor-4-androstene-3beta-17beta-diol (bolandiol) and 19-nor-4-androstene-3 17-dione (19-norandrostenedione).
The results showed that providing precursor to castrated male guinea pigs led to plasma steroid levels sufficient to maintain normal SM growth. The anabolic growth effects of these specific precursors on individual. Also total muscle volumes, sexual organs, and total adipose tissue over a 10-week treatment period. In comparison with those in the respective positive control testosterone and nandrolone groups. Furthermore, were documented quantitatively by MRI.
