After a hard 12weeks cycle containing lots of Tren,Testo and winny wich steroide schould i use as a bridge? what dose and for how lang before continuing a hard cycle?
No, its not necessary...and certainly not for the average user...
I am failry advanced these days and I still have never used it...
I always consider it though, just because it is not suppressive on endogenous test...
Though it is certainly not for most (though I am shredded up year round and burn calories like a furnace, so slin would probably be very beneficial for someone like me...)
Also the spike from exo slin is MUCH more than one can ever hope to achieve naturally, so you will have a tremendous upregulation of nutrients that can not be achieved naturally...
