Thread: has anyone switched to test u weekly for trt

I am curious if anyone has switched from test cyp/eth to test u weekly for trt and if so how are you feeling and responding to the change.

Theres almost no difference, cyp has a little less half life. Cyp is suppose to mimic your natural test a little bit better. So I'd say you wouldnt notice any difference.

If your asking about test undecanoate you wouldnt pin that every week. It has a half life between 20 and 33 days depending on the carrier oil. The whole point is to not have inject as frequently and have more stable blood levels.

I use it due the amount of time I spend traveling. I try to pin 2x a week but if I only get one it’s fine.

Haven’t but why would you. Way to much room for error with e2, Peaks and valleys of energy etc. I would pin Cyp or E 2x a week or prop 3 to 5 times a week. When I started trt my md offered test U shot 1x a month And I was like fuck that.

i was pining 2x a week with test c, noticing mood variations and very oily skin. I switched to once a week test u and seem to be on a much more even keel with mood and reduced oily skin. I will get bloods in a month or two to check my levels. I was courious if anyone else had made the switch and to see if my experience is on par with theirs.

I would guess no as most stay away from it. One or two wks after you might feel better but over time that won’t last.

Your levels are more stable with the more frequent injections. How long had you been on at this point?
