I do believe there is a 350, I don't recall which lab makes it, but it is legit as far as I know. Don't quote me on this please, but it might be from Organon. Not 100% sure though. Suspension has a very short half life, help me out on this, but I believe you'll have to inject 2xdaily about 6-8 hours apart? Again not 100% on the half life. Suspension is also very very thick and lumpy, good luck trying to actually get it through the pin. I used a 22g on my bicep once and the shit STILL clogged up. Think about getting some SOIL, sanitized oil
