Ive been using northern and teragon for quite some time, ive personnaly never had a problem with them, they might not be as strong as others but their cheap and really easy to get, but I definitely know their parabolin isnt legit, so like i said id just get their acetate or enanthate if thats the lab you want to go with, atleast you know what your getting then, plus its half the priceSounds like there is better options out there for you but it can be tough with these things I’m using a lab that is not particularity popular here but it’s given me the best results in 15 years of cycling. I’m just noting this because not everything is clear cut. Hell maybe some labs have 2 tier systems I buy 20 products at a time so they take care of me. Who knows? I don’t have experience with Northern though so I can’t specifically comment to that.
