I'm thinking it was Jano. He also dispelled the myth that peptides are as fragile as many had thought.Obviously this isn't solid evidence, but there has been a test of sema to see how long it takes to degrade and at 30 days it was hardly degraded. Can't remember if it was a Jano or liska thread.
If you are worried about bacteria then that's up to you. Personally I use very clean technique swabbing tops heavily, fresh needles everytime, etc. I literally keep a 30ml bottle of BA water in the fridge until it's done. Pretty sure the longest one was over 3 months, might have been 4 months. No issue at all.
