Been on TRT 100mg week (everyday sub q pins) 16 weeks in. Did bloodwork (provider said can increase) am going up to 120mg week. When should I do bloods next in order to properly assess? Do patients find a difference in bumps from 100-150? I’ve never been on anything but 100, trying to get dialed in perfectly.

If you were very very low on Testosterone & either primary or secondary hypogonadism, then 100mg a week would be helpful.If you were moderately low or suffering from relative hypogonadism then 100mg a week may not have been enough to notice much change.

For reference, we often start primary or secondary patients between 140mg a week or 160mg a week, depending on their levels and symptoms.

You would certainly feel a difference between 100mg a week & 150mg a week. In general, we recommend increasing by no more than 20mg/wk, to avoid overshooting your optimal dose and introducing potential side effects.Sometimes patients on 150mg do go up or down based on side effects or benefits, but that is a pretty safe starting point to determine which to do.

Overall, you can probably be tested again after 8 weeks but I would suggest following how you feel more than the numbers each test. Still have symptoms at that level which have no other cause, but were improved a bit from treatment? It could probably be higher. Little benefit change but many side effects added? It probably doesn't need to have been higher.
