If thats what you are worried about use some arimidex. Where did you get that quote from Bovey? Just so you know when you get off cycle your water retention will go away. You also can control bloat with diet as well. i hope wherever you got that the person isn't claiming that all your gains are water.
Sustanon 250 is a unique blend of 4 different esters of testosterone. The principle purpose of attaching an ester to a steroid is to make it more lipophillic, so that when injected intra-muscularly it can remain in the adipose tissue longer and is released in the blood-stream over time. The longer an ester, the more lipophillic it is. Sustanon 250 contain 1 short, 1 long and 2 medium length esters that are all delivered over time, which gives a quick release, but a durable one as well. You may think that this is a positive thing, and to patients requiring testosterone therapy this probably is, but to a steroid user its really not.
A steroid user will use a long-acting testosterone and inject it once a week. The end of a week is usually the time when a long-acting (7 or 8 carbon) ester has tapered down to its original level and threatens to drop below that level, giving sub-par amounts of testosterone beyond that point (eventhough the compound stays somewhat active for 3-4 weeks). With sustanon, that equal amount is divided much differently. Imagine a hypothetical situation where one take either 270 mg of a an ester that lasts 6 days, or 270 mg of a blend of different esters, 90 mg each, that release over respectively 2, 4 and 6 days, analog to sustanon. With the first one, an even amount of testosterone is released on each day. With the second one the entire first ester, half the second ester and 1/3rd of the last ester is released within the first two days. The result here is clear : the first two days one gets 165 mg, the next two one gets 75 mg and the last 2 days one gets a mere 30 mg. The levels peak much sooner, and drop off sooner, leaving you with less than adequate androgen levels as the week draws to a close. So for use as one would use another long-acting testosterone, I find sustanon to be poor value. The price is roughly the same so I really don't see the affinity people seem to have for it. Respectively cypionate and enanthate are much better choices. I can understand the need for a fast-acting component to front-load and kick-start gains, but even then, testoviron (200 mg testosterone enanthate and 50 mg testosterone propionate) is a much better choice. Speaking of front-loading, for this express purpose sustanon may be very suited. One could probably obtain results faster If one were to use 500 mg of sustanon on day 1, then again 5 days later on day 6 and start a cycle of enanthate/cypionate at 500 mg/week on day 11. That avoids the major crash at the end of the week and makes maximum use of the fast acting esters to saturate the system.
