Traci, I’m not an expert on this topic. But
based upon what I know, it seems to me that
getting an injection once every three weeks
is too far apart. The half-life of test. cyp.
is only about 6-8 days, so his T levels will
be good for the first week, and then they
will be painfully low again on weeks 2 & 3.
A better dosing protocal would be to use 200mg
on the first day, to get levels elevated
quickly, and then one week later use 50mg
once every three days. This will keep his
T levels at a more even level.
However, a better approach, before even
trying T replacement, might be for the doctor
to try using a drug called HCG, or a drug
called clomid (clomiphene citrate), or
possibly use them together. Both of these
have been shown to increase T levels. Have
your boyfriend ask his doctor about them.
But before doing any of that, he might
want to try a product by Biotest called Tribex
which has been shown to elevate T levels in
normal men; it may or may not help him though.
Hope that helps.
