Madeleine, the guy is not going to suffer any irrepairable side effects or anything like that. he may or may noit experience the side effects mentioned here. Sexual dysfunction is common around week 4-6...and can take 4-6 weeks to subside after discontinuance. This can sometimes be prevented with an anti-prolactin drg, but sometmes not. If he is not using any testosterone, he will surely experience sexual dysfunction eventually, regardless of whether the tren directly causes it or not, as a man physiology requires DHT in order to maintain sexual functioning. DHT is a metabolite of testsoterine conversion. Gyno is possible with tren, but not very common. Tren is a horrible choice for those involved in athletics, as many guys experience a significant decrease in cardiovascular capacity when using it.
Generally spealing, the mental side effects of tren use often outweight the physical ones. If your boyfriend already has anger or self-control issues, tren is likely to exacerbate them. If he reacts in this way, it is likely that this same reaction will continue to manifest each time he uses the drug. A some have said, tren makes a dick a bigger dick. Androgens have this effect in general, but tren seems to intensify this effect more than other AAS in those who are predisposed. Some people become violent on it. This is a result of user immaturity....sub-par emotional development. Anyone who is not able to control the drugs they put in their body has no business using those drugs. They need to grow up first.
Just watch him to see how he responds. If there are no behavioral issues, that is a big plus. After hearing a little bit about the kind of person he is and the things he is involved in (this is not a judgment of charcater, as I do not know him), I have a feeling he may not be so fortunate, but you never know. If he handles it well mentally-emotionally, the evaluate the physical aspects of the drug. Foes he have to pound on yo for an hour to cym? Maybe he experiences impotence altogether. Side effects can vary when it comes to sexual dysfunction on tren. Some guys can perform, but experience significant reduced sensitivity. Other guys have erection problems ranging from moderate to severe. It is common for tren to increase libidio and functioning at first, but this often reverses itself and start to head in the other direction. Just keep an eye open. Tren effects some people in ways that no partner should have to put up with, while other side effects may not be so bothersome.
