Building muscle with no T while on Lupron

Hey guys. Bill here. Am 57 and was diagnosed in summer of 2014 (dad had met pros cancer as well). Have burned through most of the treatments available...second chemo completed this past Feb2017. Am currently in a trial - treatment is Xofigo combined with Keytruda. Fingers crossed... this mfng cancer is so darned aggressive. Re: muscle loss...I was using creatine as a supplement until I discovered that it may increase DHT (research wasn't conclusive as to whether of not is was just the exercise that increased DHT - the dosage given to one group was more than I or anyone would take) - my T level is now undetectable (am currently only on Lupron..the other ADT therapies no longer work). I also tried Beta Alanine...it made me nauseous so...stopped. I still have not found a supplement that does not impact hormone levels (other than B Alanine) and I am having a very difficult time with physiological changes taking place. I have managed to burn the fat (running) but my once very square hips and compact torso have somewhat elongate and my hips are rounding like a woman's. Very...distressing. I am not sure that becoming soft and feminine is the way I want to live. My partner has lost his sexual interest and is going elsewhere. ***? I lived a healthy life for so long. Given that my dad had met pros cancer I was very careful with my diet...etc. My PCP kept telling me that even though my PSA was rising it was still below 3.0 so I was fine. Hello...red flag...but I trusted her. And now this nightmare. I guess I just need some words of encouragement from a group of men who know what I going through.

Unlike many who have posted here, I am not experienced in doing
lots of weights, nor of knowing the best approach as to reps and sets,
that could help (even if somewhat) while being on ADT.

I realize the exercise might not build muscle but am interested in
best approach to weights, so can do what I can.

For example, until recently, I was not adding additional weight to lift even though
could easily have done so, due to feeling I could injure myself.
(we're talking about adding 1 lb to 10 or 15 pounds, for example, mostly
using dumbbells (wont be able to use barbells, and can't rely on being
able to get to gym that has the machines)

Found out that was not a helpful approach.

When I read about studies related
to exercise while on ADT, the approach they used in the studies are hard
to understand, related to how they had the participants do the weight lifting
activities, related to number of sets, reps, and was weight added or subtracted
in the second or third sets, and so on; often referring to a term of 1RM as a baseline.

I know this topic in general is broad and often disagreement among trainers and experts.

===> But for specific of most efficient way to exercise while on ADT,
do you have any simplified suggestions on how to approach number of reps and sets
and does on lower or raise weight on additional sets, and so on ?

Am trying to keep this simple to try to ensure success of at least doing the
weight sessions, but realize I've got to do it differently than I had in the past.

Wish I could describe this better here, but just have not had the experience
with weight training.
