All right let me shead some light on your question. All the comments you hear about different test's being used are just opinions. That is all, opinions.
Keep in mind that all the tests like cypionate, enanthate, pripionate and the same. It's the identical chemicall substance, then only difference is their ester, which regulates the release rate, with propionate releasing the quickest followed by cypionate then enanthate. Now that applies only to the testosterones i listed here. There are many others, such as test suspension. A lot of the anabolic effects derived from test are not so much dose related as the way the hormone is delivered to the bloodstrem and receptor sites. This is why the pharmaceutical companies spent so much time and money developing the various test esters, as to accomodate the patients that do not respond well to say, a cypionate ester but respond better to a propionate ester, it all has to do with the hormone delivery pulse.
Now this is the reason Sustanon can deliver very good anabolic effects at a small dosage, and a small dosage is associated with less sides also. Sustanon is very stable in the bood and acts for a long time, there is less aromatization and anrdogenic side effects at any given dose compared to other tests. This is why it's a good choice for a rookie choosing to do test in a first cycle. The 4 esters in the substance act synegistically for maximum effect. 1 ampule per week for a rookie will yied very good results.
Also the sustanon is a self tapering compound eliminating the need for a rookie to plan a complex taper, and makes recovery quicker.
Overall in my OPINION Sustanon is an excellent product. A lot of thought went into it's design and is tolerated by the body very well. Sustanon represents Europe's deligence and sophistication in the field of hormonal replacement. Try it and chances are you will not be sorry.
Sincerely
