Its a choice you need to make based on how you feel, qaulity of life, etc.
It seems you are fine Rob, so do you want to pin for the rest of your life? (I find it no big deal honestly).
From age 40 to age 50 I went from 767 total, to 253 total in 10 years.
(Age, binge-drinking, statins, etc).
I've been doing 1/2-cc a week for the last 5 years (125 mg) and test back up around 600-650 total again.
The 5x dose thing seems to add up to me and many others. (5x 125 = 625).
Ive gained no muscle or strength, but mood, libido, and body-comp seemed to have improved. (real TRT dose is really not a muscle-building compound).
It will however hold on to what you have as you age.
Might want to look into an aspirin a day for thinner blood, and seek out red yeast rice (from other countries) that contains monocolin-k (10 mg) if you have lipid-issues.
Monocolin-K is natural "Lovastatin", (low dose).
But if your bloods are fine with lipids and hematocrit you may not need any of that extra stuff, just something to keep in mind if you do...
