no offence mate, im not pretending to be an expert or something but for your own good (and im saying that in the sweetest possible way:p) you have ALOT of reading to do!
clens anabolic properties are due to the fact that it supresses catabolic hormones (it also supresses anabolic hormones too but aparently the ratio favors anabolism in the end). HPTA supretion that hapens after steroid use is caused by the fact that the body shuts down it natural testosteron production to reach a state of homeostasis as an adaptation to the supraphysiological levels administered to the body.
so no, supresion is not an issue, not the one you mention that is.
?-receptor degredetion IS an issue though
where i live clen is very cheap and you can get it from a pharmachy no questions asked so i dunno
from what i have seen there are two ways to do it, either 3 week on/3 week off, you up gradually the dose the first week, keep it level for a week and taper down the third week, or do a 2on/2off where you gradually up the dose the first week keep it steady the socond and then stop using the thing (either way you could also use some tamoxifen for ?-receptor upregulation)
the nutrient partitioning effect of clen is minimal compaired to the metabolism upregulation, so muscle catabolism will be there if you want to cut. It would be minimal and if stacked with some androgen prety small, but the fact remains: calories infat and some muscle loss
if you use it right, at apropriate doses etc you souldnt face jitters an nausea cause clen is rather selective meaning it heavily prefers the b2 receptors in comparison to say ephedrine that affects b1 also and inderictly the a receptors causing that pumpy-speed like efect.
the real shit with clen is well b2 degretion (which can really fuck up your parasimpathetic nervous system), hypertention, heart problems etc
