I agree with everything you said, but I simply do not want to mess with the formula. Sure, the sides have gone probably because of many other reasons, not only the injection frequency, but I'd rather just inject 0.5ml max daily than 1.5ml every 3 days, partly because if it's daily I don't forget to do it, partly because I have those wasteful syringes so I use insulin ones. Scar tissue will be there regardless, which is why I try to do some subq shots as well, in the glute area.
Speaking of giving blood, I have two friends who are nurses, they definitely encourage me to donate blood, saying how easy it is for any nurse to find veins, even on my forehead

)))) I would do it just to get used to the process, but blood with AAS in it is useless, they throw it away as it shows signs of infection.
