There are several of options:
1: use at least 30% (total) solvent. For example 10% BA and 20% BB. This will keep it suspended at 50 mg/ml but you need to heat the AAS/BA/BB solution and then heat again after adding to oil.
2: make it at 25 mg/ml and use less solvent (8% BA and 15 % BB)
3: Use a "super solvent" (hard to get if depending on where you live, I prefer to stick with domestic).
4: A recipe of PEG400, PG, BA and oil is supposed to work well, some reckon you can get 100 mg/ml but I have not tested the theory.
On the bright side, Oxymth inj is considerd far more potent than oral administration, the ED shots will be a pain if you use a high BA approach though.
