Hell yes you can. One of my favorite sources has a wicked tri blend 100mg Tren A, 100mg Test P and 100mg Mast p. I get wood jut loading my dart.
Regarding the stament that Primo will give you the same results as Tren.....I'm calling bullshit. 8-10 weeks of Tren A at 300mg a week; beats the shit out of 1gram a week of Primo for 24 weeks. I run them both. I love primo and I love Tren. But if you want size Tren is king. I run primo once a year during winter for 24 weeks. I love it because I have no noticeable sides and I can blast other compounds. With that said. I have very few sides with low dose test and 350mg Tren a. If I could run Tren year round I would, but I'm an old fuck.
Two completely different compounds. I agree that they are similar I the fact that you keep the vast majority of your gains, but the similarities end there.
