How many times do we have to go through this? If you want to gamble, go with IP, personally I would spend more cash to ensure that my cycle will not go to waste.
I had IP stuff tested several times, here are the results:
Tren (80mg/ml) = 91 mg
Tren (80mg/ml) = 53 mg
EQ (200mg/ml) = 198 mg
Anadrol (50mg) = no active ingredient
Anavar (10mg) = 9.93 mg
Nathan ran like 3 of his winny tabs and got nothing out of it ~150mg.
You don't mind taking chances, go with IP
