Every drug has its best metabolic pathway. With Anadrol aka Oxymethalone an oral tablet is the best method of delivery.
So if I had a few kilos of Oxymethalone powder (pure) I would get the proper accessories and put it in capsules for quick easy usage and resale. If I had SEVERAL kilos of Anadrol powder I would invest in a pill press or pill making machine, get the proper accessories and press several thousand 50mg tablets. Under no circumstances would I convert the powder to a liquid and inject it.
Disclaimer: I have never seen this done before in my entire life and I have never stood in a friends "lab" and watched him manufacture 10,000+ 50mg Anadrol tablets. No I have not.
