    Lump after sub q pin

    When I was injecting SubQ TRT made with cottonseed oil I also got angry red and sometimes itchy lumps - almost like an allergic reaction. I stopped getting those lumps when I switched to grapeseed oil from Empower. Now I alternate SubQ and IM for no reason other than I feel no different with...

    Combining tadalafil and sildenafil

    How long did it take for the back pain to subside? I recently tried 5 mg Ceebis and had to stop after day #3 due to the low back pain. It seemed to emanate from my hips up to the lower back and even down my legs a bit. It was so bad I was unable to sleep, so I stopped and after a day or so the...

    TRT and HCG - ED

    At a minimum it helps cosmetically. If your sack size is important to you then HCG is useful. I tried it and my sack size definitely went back to its pre-TRT state, but other than that it did nothing for me. Ultimately I dropped it because I didn't care enough about the cosmetics.

    New Vitamin/Supplement/Nootropic Suggestions

    Tadalafil helps with nighttime urination? I did not know that. I'm up 2, sometimes 3 times per night. To what degree would you say it helped you? I also had brain fog which resolved when I started on thyroid meds.

    Newbie searching wisdom and advice

    In my case the brain fog lifted after I got my thyroid levels worked out. Testosterone improved my physical condition, but the mind fog persisted. That caused me to dig further which led to thyroid treatment.

    SubQ experience?

    Help with Cytomel

    My numbers were very close to yours, and I was prescribed the extended release version of T3 from Empower. As I increased the dose I went through a rough patch of high anxiety/stress and very poor sleep for 3-4 weeks. After that things returned to normal.

    Do most user's TRT stories seem to be ultimately negative?

    55 yr old guy here. Luckily never had any ED issues. I started TRT about 10 months ago due to fatigue (mental and physical). The TRT helped my physical issues - body composition has improved and recovery from workouts is much better. My mental issues (mind fog and general lack of interest)...

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
