dont worry about Yield or Error... 2g = 40cc@50mg/cc... And the Kits are crap.. i would rather make my own Kit.. I bought a 2g kit.. and i was thinking it would be enough oil and BA to make it as 50mg/cc but it was only like 25cc final for 2g thats like 80mg/cc or something and i was shooting that for my first cycle.. i got really big.. but i like it around 50mg ED (everyday) but if you're worried about Yield.. i would say go with 175cc of soultion per 10g coversion.. so thats 157.5cc of Oil, 10cc of BA, and 7.5cc of powder (1g = 0.75cc).. that should put you no less than 50mg/cc or no more than 60mg/cc.. and thats good 1cc everyday... thats a lot of tren between both 10g conversions that 350days... so i suggest making it as you go.. maybe do only one 10g conversion and then the other one later
