Well, that is a good question. Did I mention that they are newbies on their 1st cycle? I'm just helping with a problem, not a sponsor. I'll pass that along. He says they followed proper sterilization procedures (alcohol swab the top, new sterile needle each time, alcohol swab the injection site before and after & band-aid etc.)
He said for the 1st 48 hours there was a "lump" then it began to get red but the lump went away. I would think that would be the bolus of the injection which then slowly dissappated. By the way, this was his 3rd injection. Each one has increased in effect. I have advised him to cease immediately. His training partner has had NO side effects whatsoever. I would think that he has had some sort of reaction to either the boldenone, the oil, the preservative/bacteriostat or all of the above.
