Been on Syntherol for about 10-11 days now...running it Big A style.
Two things that have been stated by Big A and others, but not really noted or better yet stickied in the go-to threads that they put up;
1) It is a VERY thin oil. It's not as thin as a peptide, but it's the thinnest oil I've ever injected. Go small gauge(25-30).
2) Inject SLOWLY, very slowly. I read thatbloke's post about leakage, I had some, but then I decided to inject real slow and no leakage whatsoever. Dose didn't change, etc.
And one of my own things;
3) There is a "response" to it, so it's not fool proof. I'm doing all 3 heads triceps, both sides biceps, and 1 head delts. Usually my delts and lats respond best, then triceps in regards to growth and biceps very last. And much like that, my delts have become the most pronounced followed by triceps but very little of my biceps have. Biceps are bigger with it only being 10-11 days in, but my delts and triceps as usual have grown faster.
Just started the 2ml'er days. They say this in all their posts, but stretch, really...stretch. Get a massage too. Deep Tissue massage 2-3x week is on my plan to get my arms really ironed out. Best stretches at home are the ones DC uses for triceps and biceps, I do those throughout the day. So far only a little knotting and tightness. Nothing like people exclaim, worst issue is the amount of time I have to dedicate injecting, etc., but that's just effort nothing against the product.
