i have 2 questions here that i cant seem to figure out so lets ask the pros...

im currently on a sust 250/every 3 days and tren ace 100 .75ml eod. arimadex at .5 then 1.0 eod switching between the .5 and 1.0. i am currently 8 pins of sust deep and did my first tren pin about an hour ago

first question is why the hell am i getting bad E.D.. i thought testosterone did the opposite considering the last 2 times it was a towel rack on command yet this time i get bs and aggravation... Ive reduced the salt in my diet and tried avoiding stress and nothing helps.

2nd question is from what my "guy" mentioned. i have 1 bottle of hcg 5000 iu and enough nolvadex pills but my guy said i should probably consider 2 bottles of hcg... is he right or just scamming me for more money? i always thought 1 bottle would be enough for 30ml of sust and 15ml of tren, plz gimme some feedback... hopefully not harsh feedback cuz im still a noobie considering i just followed my friends instructions last time and im doing it solo this time thro
