God, I must be one of the lucky one's as I expereience little to no discomfort from any injection, even IP injectables. Yet during the past few months with all the people bitching about the resulting pain from T400, I was a bit worried about implementing it in my cycle. Well, last weekend I gave it a go and once again, experienced no pain at all after injecting in my glute. I usually shoot all my shit in my arms and shoulders, but I didn't want to regret doing that if the T400, did indeed prove to be painful. Well, this coming week, I'm going to muscle it in the shoulder just like everything else I shoot. What I'm trying to stress is that sensitivity to injections is really an individualized manner, just as one being prone to certain side effects are also individualized.
