Those are the sicomed 100mg/ml/amp phenylprops. It is a fairly short-acting ester, but longer than prop, so a good dose would be 2 amps (2ml) EOD, which would work out to 700mg/wk. Or you could go 2 amps M/W/F which would be 600mg/wk. It is very good stuff, I personally like it a lot because it's so inexpensive. Using a shorter ester like this will cut down on water gain.
The T400 is composed of longer esters and should be injected once, or preferably twice per week. The benefit here is less to inject, and less often. However, T400 has a history of high BA content and supposedly hurts like a bitch. Mixing it with your eq should help that.
Personally, I would go with the testolent, but do the math and figure out which is cheaper.
