What’s your current dosage and protocol?
Also, do you have recent labs?
I was in the same boat as you, hit or miss libido and some ED issues (going soft during the act) My dose was 140mg Test C, (70mg 2x/week), IM. I also tried increasing the dose but never really achieved a great libido.
The more I read on here and some other forums helped me figure out that me being a lowish SHBG guy meant I needed more frequent injections and a lower dose. And sometimes more isn’t necessarily better. Remember, the average male produces around 5-10mg of testosterone per day, so at the low end that’s 35mg and the high end it’s 70mg.
At trough, my TT was around 1200, free T was around 32 ng/dL), E2 was 62 and SHBG was 18. So on paper my numbers were good but still no libido or erection quality.
So I went down to 100mg per week and I shoot every other day now instead of every 3.5 days. I also shoot sub-q and I vary my weekly dosages. For example, week 1 I shoot 100mg, the next week, I shoot 110mg, the week after I shoot 120mg. Then I start back at 100mg. It sounds more complicated that it really is.
It made all the difference. I’ve been on this protocol for about 4 months and libido is raging, erection quality is like when I was a teen and wood every morning without fail.
There’s a post on here (that’s really long) but it had some info that helped me out tremendously.
