I just finished my cycle of 10ml a day, 5 days a week for 4 weeks. I was very disappointed with the effects. I did not experience any substantial nootropic or antidepressant effects. I am unsure if my focus is improved, but my productivity has actually been going downhill (which is probably unrelated). My memory may be somewhat enhanced, but the effect doesn't come close to what I've experienced with piracetam and CDP-choline. Cerebrolysin did not make piracetam or any other nootropics work better, nor did it reduce my tolerance. Overall, I'm not sure if Cbl had any effect on me at all. This thread made me think it worked for pretty much everyone, so my results have been very surprising.
Given the cost of Cerebrolysin and injection supplies ($410 for me), the difficulty of administration, and the lack of a pronounced effect, I will not be using Cbl again.
I did learn quite a bit about IM injections, at least.
For IM injections, I highly recommend avoiding the glutes entirely (you risk damage to the sciatic nerve and dorsogluteal artery, plus you are much more likely to inject into fatty tissue, plus it's a really awkward angle). Instead, I recommend the vastus lateralis and rectus femoris. Each can be divided up into three injection sites about two inches apart, centered on the middle of the thigh. I find it works well to stretch the skin and pierce the skin quickly with a dart-like motion, but then to slowly insert the needle the rest of the way. You need to be able to feel when the needle is in the muscle and stop at the right depth - usually about 1.25". Sometimes it's difficult to pierce the connective tissue surrounding the muscle, and if you're on the edge of the muscle, you also risk going through it entirely (hence the need to stop at the right depth). Wait at least a week before injecting in the same site. With good technique (including pressing the plunger slowly - 1 minute for 5 ml), the site will be sore for a few hours, but the next day it'll feel fine.
