I used it once few years ago. It is one if not the most painful injectables stuff.
Well stuff in other case is good. Suspension is water based steroid and usually have no ester attached so actually start working as soon as they are injected. When it is injected it work only for 1 day,.... due to that, it must be shot at least ED or even 2x/day. If I remeber right the half life of suspension is 8h.
Because of so fast acting this stuff cause a very rapid spike in blood levels and they cause strong water retention and elevated estrogen levels what lead to gyno in worst cases.
Here is a table to compare the % of actauly testosterone in each of the different types of esters:
Testosterone suspension : 100%
Testosterone Propionate : 79%
Testosterone Phenylpropionate : 66%
Testosterone Isocaproate : 71%
Testosterone enanthate : 69%
Testosterone Cypionate : 67%
Testosterone Undecanoate : 61%
Ohh and you are right sarcasm,... it need to be taken with BIG needle in other case easily stucked.
I always shakeing amp before pull out suspension and before change a needle and give a shot I shakeing it again in other case cristals stucked so easily in the needle. I remeber when I use a normal needle like for oil substances first time and I stick myself 5 times to complete one shot LOL.
