yes i suppose it does kick in pretty fast because of it´s genious testosterone mix,the propionate and phenylpropionate kicks in really fast so when using sustanon one really gets results faster than when using enanthate or cypionate that takes a little time untill it kicks in and starts doing the job,i myself really like the faster esters and my favorite is propionate even if it recuaires alot of injections/cycle one can use it and feel safe from all side effects if they kick in just lower the dosage of the prop or stop and then you are fine from the side´s,The sustanon is containing 100mg long ester that can cause some people problems that use it ed or eod because it is becomming a high dosage for the beginners that would grow really good on 500mg´s/w and at that sustanon dosage the total would be=1750mg/ed or 875mg/eod and this is pretty much for some persons that have problems with the sideeffects,some seems to get them at very low dosages when on testosterones for some reason that i really dont now and have not bothered to check up either,so i feel pretty lucky that i can do 1000mg/w of testo with out any bigger problems(of course there is always sides when using steroids,but nothing that bothers me,so i am pretty lucky i suppose when compared to people that gets gyno on 400mg of testo/w even after they have done a few cycles and needs to use armidex or letrozole constantly according to them selfs!
So why is it that some persons are more sensitive to the bad effects/side effects when using steroids than others??
Would be intresting to know for once just to learn why!
