Testosterone will increase libido, wellbeing, lbm etc. But might cause estrogen related problems.
Deca-Durabolin might have a negative impact on your libido, has positive impact on joints and muscle tissue gains/fullness.
Trenbolone i would recommend waiting for, but would be my personal choice at 350mg/week, positive impact on libido if prolactin is controlled, extremely anabolic and can be used at 25 eod to hold on to skeletal muscle, huge strength gains, very good lbm gains, low sides with minimal test (200 test is very low which is perfect). It is bad on hair, can cause acne, aggression/bad mood, insomnia, night sweats, tren cough after injection (tightening of the lungs), etc
You can also look into trestolone 200-350mg week, no need of test. 10x more potent than test, but note, it was created to reduce sperm count.
