Similar to previous experiments, adolescent and adult experimental groups received intraperitoneal (IP; Hoseini et al., 2009 (link); Witzmann, 1988 (link)) injections of nandrolone (7.5 mg/kg; 19-nortestosterone; Sigma Chemical Co. St. Louis, MO), whereas control groups received IP injections of vehicle, which consisted of sesame oil (0.02 cc/10g of body weight. As 1 mg/kg of AAS is sufficient to restore endocrine function and reproductive behaviors in rodents (Clark and Barber, 1994 (link)), the dosage used in this experiment reflects a high dose. Since periadolescence in rodents extends from postnatal (PN) day 28 to PN-60, (Spear, 2000 (link)), nandrolone injections alternated with vehicle injections, were started at PN-33 until PN-42 (Fig. 1 ). Furthermore, to confirm our previous experiment in adults (Parrilla-Carrero et al., 2009 (link)), adult male mice (PN 88-97) were also tested following the same CPP injection protocol as in adolescents.
19 nortestosterone
Manufactured by Merck Group
Sourced in United States
19-nortestosterone is a synthetic anabolic-androgenic steroid. It is a derivative of testosterone, with the 19-methyl group removed. The core function of 19-nortestosterone is to modulate the activity of androgen receptors in the body.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
