nandrolone

Many of those (testosterone, nandrolone, masteron, trenbolone, trestolone) also interact with prolactin and there’s occasional discussion about pregnenolone as well.

This would check out with the positive impact that anabolic steroids have on insulin sensitivity too, given literature showing that many of them are serotonergic (IE, nandrolone).

Some people back in the early bodybuilding days would use nandrolone (better known as Deca or the other variant equipose) as a stand alone cycle but that isn't recommended now.

While testosterone is not well-known for helping to heal ligaments/tendons, some HRT compounds (such as nandrolone) that are occasionally prescribed by doctors/urologists, have a lot of anecdotal accounts of reducing perceived joint pain.

If I had designed this protocol, it would've looked like standard Testosterone Replacement Therapy (TRT) plus an injection of nandrolone decanoate every week (which is great because it heals your joints).

In short: if you need to do it, drop trenbolone and boldenone, switch yourself to nandrolone, monitor your BP and hematocrit (you can ask your doc for telmisartan) and limit yourself to something like 400mg of testosterone a week.
