Thats an excellent analysis, definetely will consider your opinion. In the end my friend who owns the lab and 2 brands, will have the last word - since im an experienced seller, but he is an experienced producer, that sold millions of products that he created.I'm throwing out my 2 cents but it's just a point of view.
If you want to use castor use more bb (40%) to make it thinner but still it will be too thick for a 3ml injection. You must to press on that plunger forever to move or use a 22,21G and most people don't even want to hear about that. Also it will be harder for you to filter and work with it.
You can use EO like 20-25% to be more thinn but it's defeats your purpose to avoid eo. Pharma use castor because allergic reaction are low and release time is slower. Also some pharma companies use eo for some injectable but people have double standards
MCT will probably sell because that's something everyone has used, oil is a bit more acidic and the bacteria it's harder to grow, also thinner.
A alternative to MCT I would consider peach oil. Thinner similar to MCT,a newer carrier oil that a ugl is using (you will be first that I know),and has a bit of nostalgia in the mix for the user of real Balkan. I really like Balkan products and peach oil.
GSO it's the most tolerate oil by everyone. Most people get along with it and isn't very thick.
Nowadays I use EO as a carrier because it's thinner, easy to work with it and I don't believe in myth.
But most people do that's why EO has a bad reputation because it's a idiot on YouTube like Vigorous Steve that said that and that's also why castor oil is popular because same idiot said that but most people didn't even used castor 100% as a carrier to see how fun is to inject that and no ugl that I'm aware is using castor for people to try it but somehow people prefer castor oil.
That being said I would use peach oil for my ugl if I want a alternative to mct and to be the only one that use peach otherwise I will go with mct because if isn't broken don't fix it.
Thank you for this effort, im deeply appreciating it!
