The beta decay of Pu-241 forms Am-241 ; the in-growth of americium is likely to be a greater problem than the decay of Pu-239 and Pu-240 as the americium is a gamma emitter (increasing external-exposure to workers) and is an alpha emitter which can cause the generation of heat . The plutonium could be separated from the americium by several different processes; these would include pyrochemical processes and aqueous/organic solvent extraction . A truncated PUREX type extraction process would be one possible method of making the separation. Naturally occurring uranium is not fissile because it contains % of U-238 and only % of U-235.
First when talking about steroid doses don't talk about them in mls, always mgs. tren a is usually taken a minimum of 50mg per day. If you think you can pin it one a week you need to do wayyy more research. You can get away with eod but ed is the standard. You can pin it right along with test. So daily do 50mg (or 100mg eod if you have to). Then 2 of those pins a week do with the test in the same syringe. Also if you are going to get blood tests monthly tren won't work. Even if you can make it two months it's tough. Most don't do tren less than 6 weeks and it shows up as estrogen in a blood test which will send huge red flags to a doctor. Not sure how long it takes to clear but you would want at least a couple weeks off I'd guess.
