TweetI've converted and used 4-AD Cypionate. I got it at 400mg/ml. Converted 20g of powder. I don't remember how much BA and BB I had to add. i think I used 10mL of BA and then added BB until it completely dissolved. At that point I added the oil until I had 50mL total. This was filtered also. Worked well at 1200mg/wk. Worked "ok" at 800mg/wk.
Try https://www.1fast400.com for the powder. It's pretty cheap, especially considering 50mL at 400mg/mL will last you quite some time.
