You might first consider less disruptive ways to raise testosterone, such as Natesto or enclomiphene. Regular TRT has a profound effect on various upstream hormones. At a minimum TRT suppresses GnRH, LH and FSH. It may also affect kisspeptin, progesterone, DHEA and pregnenolone. Although many men seem to do ok in spite of these effects, others end up experiencing problems with libido, sexual function, etc.

If you do proceed with TRT then at least consider physiological dosing. As a "skinny guy" you would likely find that 150 mg TC per week is much more than you need to attain healthy normal levels of testosterone. Consider 100 mg or less. Don't get caught up in the "more is better" mentality surrounding testosterone. More is not better. You're looking for the minimum dose that gives you symptom resolution and normal physiological levels.
