OP, please dont listen to this advice - its TOTALLY incorrect. Suggesting to someone not to include hCG on cycle because you THINK their testical will not bounce back is the most idiotic irresponsible advice one can give on the use of hCG. CanYOuDigIt, please refrain from handing out reckless advice to new members, or anyone else for that matter. If you dont know what youre talking about, keep your opinions to yourself. Thanks.
When used properly, hCG prevents testicular atrophy. This is not something "we" thought up recently. Its medical science.
hCG is to administered on cycle @ 250iu twice per wk (or more frequent in some cases) SubQ. You can administer it IM but as already suggested, SubQ is a LOT easier.
B12 is administered intramuscular, NOT SubQ. You can include in the same pin as your Test E if you like. Some will argue that, but i've started doing it and as do other Vets on here, and hundreds and thousands of others still. OR, you can pin it on its own if you feel more comfortable..your call.
