As a stand alone, I would recommend 30 days of Anadrol, 100 mg per day. Yes, you will retain some water which you will lose afterwards, but if you train well and, most important, do a good aftercycle, you should be able to keep most of the strenght gains AND at between 5 and 10 pounds of muscle mass. As I said, the aftercycle is here more important than the cycle. I recommend starting the intake of clenbuterol immediately after the Anadrol cycle, starting with 40 mcg gradually climbing up to 100 mcg per day after one week. Do this for another 30 days, and then judge for yourself what your lasting gains are. Due to the anabolic effect of clen during the first 2 weeks of intake, you should be able to keep most of your strenght gains while losing a little weight (water and fat). And as you know, strenght leads to muscle mass...
Don't forget to take yohimbine (25 mg a day) simultaneously with the clen, otherwise your beta-receptors will be saturated too quickly.
In some countries, such as Mexico, there are very few laws or restrictions in place when it comes to where to buy steroids. It’s possible to get them in pharmacies without a prescription, and some even obtain them from veterinarians. Keep in mind that while this practice is considered legal in these countries, there are very strict laws that prevent you from carrying steroids across international borders. These penalties often include jailtime and large fines, and they can have lifelong impacts. If you choose to purchase anabolic steroids for sale in other countries, do so safely.
I honestly can't see any reason why not including test would somehow hinder the gains you keep post-cycle. Once you're in post-cycle, nearly all synthetic hormones should be flushed out. There isn't a homeopathic effect or anything; whether that hormone was trenbolone, testosterone, or superdrol is largely irrelevant at that point. The main factors that determine how much you retain is (a) your current body composition and (b) your pct. Furthermore there are some pretty potent orals out there that will be just as effective, if not more, at making muscle as most injectables.
