The present study was done to evaluate the effect of boldenone undecylenate (BOL) on growth performance, maintenance behaviour, reproductive hormones and carcass traits of male rabbits. Sixty apparently healthy New Zealand White male rabbits, 5 weeks of age, were allotted to 3 equal groups. Each group was subdivided into 5 replicates, where the first group is control. The second group (B1) comprised rabbits that received 2 intramuscular injections of BOL (5 mg/kg) with 3 week intervals (9 and 12 weeks of age), while the third group (B2) included rabbits that received 3 intramuscular injections of BOL (5 mg/kg) with 2 week intervals (8, 10 and 12 weeks of age). The end of the trial was after 4 weeks from the last injection (16 weeks of age). The results revealed that the treated groups had a significant increase in total body weight, daily gain and feed efficiency, with a significant decrease in feed conversion ratio (FCR). Ingestive, locomotion and grooming behaviors were significantly higher in treated groups. Lateral pasture and exploratory behaviors were significantly higher in the control group. Administration of BOL resulted in a significant increase in dressing % and a significant decrease in testes %. Groups treated with BOL had a significantly (P<) decreased serum testosterone level, simultaneously with a significantly increased estradiol level. The results indicate that BOL improves performance and carcass traits. Furthermore, there are hormonal-behavioral correlations through enhancement of ingestive and locomotion behaviors of treated animals.
In most cases one or more of these effects will be noticed by all users to at least a slight degree, especially insomnia and excess sweating but heart rate issue will prove to be very individualistic based on individual sensitivity. These are the Trenbolone effects that can be very brutal, for if they exist they can exist in a far more pronounced manner than you have ever experienced. For many men they can become too much and for this reason it is often advised you stick with short ester base Tren such as Trenbolone-Acetate; this way if the side-effects become too much you can discontinue use and have it cleared from your system in about 72 hours; if youre using Trenbolone- Enanthate youll have to wait for over a week. As for libido, in most cases this is easy to control through responsible use; Tren will suppress natural testosterone production dramatically and for this reason testosterone therapy is a must when Tren is being used. Always remember, responsible use is your best friend; if you use responsibly the above side-effects while they may still occur the odds will be far more in your favor.
