I find it highly unlikely bro, that primo will affect you even at 300mg per week, I aint ever used it at less than say 400mg weekly it gave great results, and I noticed its effects weeks after I stopped injecting it, T3 levels, they wont be affected, might see slight increase in lipids and chlesterol but apart from that your good with primo.
Out of interest what kind are you using ? Is it the turkish primo ?
There are many fakes about mate, some contain phenyl propionate, Turkish is the predominatley available source just now.
Good luck santo and good to talk to you again, bbigman2000.
