I love "Anatest" Propionate (vet shit!!). I know PVL has a new one out thats awesome, i think its 250mg/cc. My little bro is using it right now and is loving it!!
I dig LFC Prop myself. I understand Viromone is supposed to be good, but there's also a good chance you can get bunk shit from what I hear at the same time. So the moral of the story is, LFC is good shit.
IMHO Testovis is Nos1 but is only 50mg/ml so injecting 2ml for every 100mg and comes in 2ml amps (human grade)
Second is British Dragon Prop which is 100mg / ml
