You can try adding some ethyl alcohol as preservative, as it is less toxic than BA it has already been done GenXXL - AXIO - Syntrop - Biogen and their offspring | JuicedMuscle.com but you will need at least 95% pure ethyl alcohol, not just everclear as it has 30% water. and water doesn't mix with oil. You may even need water-free absolute alcohol. You can first try mixing 99% oil and 1% alcohol to see if it holds fine, without wasting gear. Nobody really knows if/how long 1% alcohol will preserve gear (albeit oil doesn't feed microbes as well as sugars or even proteins do), so all alcohol preserved gear must be injected within 1 month (preferably 1 or 2 weeks), to be on the safe side. Seems to be an Arnold copycat.
