Igf1-lr3 won't do anything for site enhancement. MGF will to a small degree, but nothing like synthol.
Let me see if I'm parodying these responses correctly... Ahem, "Dude! I never tried synthol, don't know anything about how to use it and have only seen horror stories posted on boards and vids of freaks with implants that claim it's synthol. So, obviously you shouldn't use it! Trust me, I know nothing about it, but don't use it!" I'm sorry, but this is what this sounds like. How can anyone rave about how stupid it is when you have little to no experience with it?
My advice is go somewhere online where synthol is used and people who have experience can tell you what to expect, how to use properly, and whether it's worth it or not. Using it incorrectly can be a a lot of work with no results. I don't really like your proposed method and it doesn't sound like it's the best route.
ml/day wise.
I've done 2 runs with it. One was my "own" idea of what ml to take on what day and so forth and it ended up with getting no results with a hell of a lot of injecting! And, I'm talking no results. The second time I just focused on one muscle to keep it simple- in fact, one head, outer bis. This time I followed a tried and true protocol and ended up not being able to do it. It was too many mL for my little arms to handle. But, I did the best I could with it and ended up gaining a decent amount all things considered. And, my arms looked totally natural when it was all said and done.
At this point, I don't care about morals. Morals and bb don't mix. Plus it's all silliness anyway. We're taking GH, peptides, aas and on and on and then worrying about it being "cheating" when we site-enhance with synthol..... but not igf-1 or mgf. lol. Yes, I get the difference and I get why people hate the idea of synthol. But, if you educate yourself, keep a sterile environment/clean, and use good techniques you can do some reasonable good with it. Abuse it and then you end up tearing a muscle or worse- end up looking like a clown with oil bags for arms.
I'm not sure whether I'll give it another run or not. It is a tremendous amount of work. But, done correctly and tastefully can be a bit plus for some of us.
My buddy is on IGF now, coming off a big cycle and his arms are growing by the week..
