The best answer I can give is that treatment is very patient specific. I am not comfortable with administering 200mg of T (delivering 20mg to the bloodstream), even though many are recommending same. The
DHT boost (which few even think to assay) can be troublesome. So can estrogenic conversion. Still, I do like to try a gel first, IF that is what the patient and I decide together.
You usually cannot get T levels high enough on a transdermal for some men. Or it is a lifestyle decision (convenience, risk of accidental transfer, etc).
BTW, I have seen
testosterone frost produced by 10% creams/gels, too. I would never go with a 20% mix. My favorite is 5%.
Regular, low-dose
HCG supplementation has benefits beyond the aesthetic consideration of testicular size.
What a fascinating topic!
