So what's the current thinking on dosage/duration and non-suppression vs. temporary suppression vs. permanent suppression?
My LH usually sits around 3-4.5.
A single dose of 5-10mg of testosterone base will drop it to ~0.5.
1-2mg will drop it to 1-2.
Haven't ever taken test base indefinitely to know whether it'd take LH/FSH to <0.1, but trt test cyp injections always did, so I assume it'd be no different. My natural testosterone production is pretty solid these days so I'll only take it if stress levels - especially gym related - are particularly high.
Tbh, I really don't like test as a hormone to supplement - it just aromatizes way too much and gives me moon face, water retention, and most other symptoms you'd associate with a higher estrogenic load.
DHT would probably be a better hormone to use if you're planning on taking low, sporadic doses.
