last time i made for 250mg/ml. shit got all gelatinized and never completely uncrystalized. trying to make for 200mg/ml but can't find anything that uses bb accurately.
Take your powder volume in ml as being about .75 of its mass in grams; eg, 10g of powder would count as 7.5ml.
Cyp should hold comfortably at 200 or 250 in 2% BA, 18% BB. If you want it extra thin then you could split the remaining volume 50-50 between EO and oil.
So, making 10g at 200mg/ml would be 50ml total
Powder volume = 7.5ml
2%BA = 1ml
18%BB = 9ml
Subtotal = 17.5ml, remaining volume is 32.5ml, either all oil or an oil/EO mix to be added after the powder has dissolved in the BA and BB. If you use EO, keep away from naked flames during the preparation. I recommend using a bowl and pouring boiling water into the bowl and sitting your beaker in the water. Replace the water as it cools. Mind the beaker doesn't tip and ruin your batch.
I'm currently using some prop made at 100mg/ml with the above recipe of 2/18. It's suiting me well enough. QS's recipe is using 20%BB. You can go down a lot lower and an enan recipe could hold 250mg/ml with no BB. The BB helps to thin the oil, though, and reduces the likelyhood of the compound dropping out of solution in the muscle.
oh, not really taste good, but i don't get the immediate raise in blood pressure and the headache, either. d-bol seems so much subtler than a-drol. it's got a rather salty taste...
now, i've been cooking stuff a certain way for a while and have seen you fellas do it a bit differently. does it matter if i:
1)heat my oil
2)add heated oil to powder/ba/bb
3)then mix and draw thru filter then into sterile jug?
So long as you end up with fully disolved powder, it doesn't really matter how you get there. I've only ever done small batches so I just push it through a filter straight into a sterile jug.
