I had a perfect method in sight. However, due to constraints such as accessibility, limited skill level and knowledge, and resources, as well as being watched, I had to go through a series of upgrades while trying to prepare my ideal method in the background and failing. Now that I have completed my latest upgrade, I'm now ready to actually go at preparing the method, which all comes down to trial and error.
My method never changed. But I did have to make adjustments like trial and error.
As for my secondary methods thay I keep upgrading, yeah… there were flaws and I had to do just that.
Worked on project bearshaek (adrenaline self destruct mechanism) but saw it as a risky last resort method, then 2m2b+loperamide and pgp inhibitor, upgraded to SN, but that was an unusable stepping stone considering I take the antidote (Vitamin C) daily. Upgraded to Azide, but that's definitely a risky and dangerous method, I discarded it later when I worked on the Nyan Cocktail (predecessor to the yew and also bootleg DDMP). I've done my research on this one, and I could stop there. But I want to make the yew as a final upgrade. And I can make a choice on the two methods depending on whatever given circumstance there is for me.
Nyan Cocktail- Undetectable killing agent, peacefulness is unknown, but it should be bearable considering the added ingredients. I'm uncertain about time, but it should be faster than consuming raw agent by itself.
Yew Tincture: Will certainly be peaceful considering that it's perfected, quick, detectability is uncertain, but I imagine it would with the lack of plant matter.
