Hi Ian, in response to your request on the Heart thread I've come in to have a look.
I think this has been answered before (more or less).
I personally think deca is a better drug of choice for a first time user. Mainly on account of the total side effects likely; compared to those of test.
Shutdown will typically take 3 weeks to really kick in and as previously said the shutdown is the same for either (although the shutdown with Pure test is more rapid, the endf reslut is the same). The suppression of the libido, is also going to be the same end result for either, test just feels better initially as your body see's a higher androgen count, but after a few weeks they fall of regardless of which one you use. Therefore side effects such as aromatization to DHT & Estrogen should be of a main concern. As Deca doesn't/cannot convert to DHT and only has a slight estrogenic conversion. This is why I favour Deca.
The previous thread is as follows
deca on its own ?
