I haven’t had the chance to read all the replies, so I apologize if someone has mentioned this already.
In my opinion, it’s fantastic that you’re here seeking information for your husband and taking the time to do your research.
First and foremost, I recommend getting some blood work done to check his markers and ensure everything is in good shape.
Next, it would be beneficial to establish a routine that focuses on getting back into the gym and eating right after a period of falling off track. It would be a shame for him to start using anabolic substances without training or nutrition in place to maximize the benefits.
I’m not certain of your husband’s age, but a more conservative approach to cycling might be wise, especially if he’s not an active bodybuilder or doesn’t aspire to be one.
Consider exploring cycles that incorporate Test, Primo/Mast, and HGH.
I hope you find this helpful!
