Preferred method of sterilization

Hey guys, I've been doing a bunch of research in hopes of brewing my own batch here soon and noticed that different people sterilized differently and wanted to see which method you guys preferred. Some recommend sterilizing the oil before mixing, some state to mix everything then sterilize and filter last, while others state to mix, filter, then sterilize. Which method do you think is best? Looking to make Test P, Tren Ace, and NPP, possibly Winny as well but idk. I know that the Tren oil will have to be sterilized before mixing as it degrades with heat. I was also wondering how you add the heated sterilized oil to the tren. Are you supposed to let it cool in its container(for me muffin pan most likely) or do you pull the desired amount through a syringe and let it cool that way? Not sure if the heat will destroy the syringe or not.

i normally heat all the compounds together but the oil. Then one time is cristal clear the mix i add the oil until the 100ml that i marked previously myself (that way i void to count ml), my beakers are measured previosuly with a custom mark in 100,150 and 200ml. So i will not take care of counting the oil. Then i continue heating the mix with the oil to 220F/110C whatever compound is. testo, tren a, tren e, mast, deca, npp. MY tren never ever got brown at this temp, it always came with a GOLD color. Then i keep stable this temp for 10 min and stiring non-stop with a magnetic hot plate that i have that stirs by itself. Then if the gear is for myself i even dont filter (it is loose time, at everything is already sterilize) there is no bacteria that can survive those temp for more than 2-5 min. Yeah you can think but the bacteria is inside, and is true, but dead, and dead will not do nothing in your body, as you are adding also BA to prevent the grow of them inside. If you filter can happen that it take way to long if you use a syrenge filter, or a plastic system that sometimes melts or breaks being the plastic inside of your gear and will produce pip. I have a glass filtration system with a electric pump and even i dont filter if it is for my self. If it is not or you dont know when you are gonna use it, then filter, it will be a cleaner solution, and safer for a long term. When i filter, lets say in a hard way, ehehhehe, i use a 0.22 PTFE filters, and in a more soft way i use a 1mm whatman that filters way too fast and i avoid any possible hair or big things or even dust that maybe felt down into the solution.

That is my way to go. some people will not agree with no filterins, but my experience for years showed me that sometimes filtering fucked up everything because the neccessary precaution were not taken. For ex if you have animals at home, filter dude, it will be hair flying around for sure. Also i do filter everything that is fast acting, lets say propionates, suspensions or TNE or acetates, they are already hard by themself so better filter them to be safer and avoid that little pip that they can cause. But long sters for myseld, i do not filter them and never ever had any pip

Good luck and post results and methods!
