None yet, will order sleeve stoppers from gpz now they are back up, but I'm stocked up until next year. Just doin research right now. I won't order until after March or April 2018 as I buy enough for a few years at a time
I want to find out if the sleeves can hold up to guiacol from gpz before I buy nothing but sleeves as I like test base pwo and guiacol can eat stoppers. If they can't hold up I need to get pre sealed and sleeves
I will only get the sleeves and vials from gpz as they are guaranteed to air tight fit. I can find many other items cheaper elseware, filters, filtering syringes etc. Hell crimper with tops new for $50 on ebay, haven't even checked wish.com or geek as I'm good with my list sofar and need to start downgrading as I'm around $2,000 between suppliea, raws,peptides etc. Got too excited watching new source thread and have most his products on my grocery lists lol
