[QUOTE="madman, post: 129499, member: 13851"] Of course there are differences in some of the materials used between preloaded syringes and Luer lock hub, polypropylene slip hub, fixed insulin syringes but when it comes to the materials used for the plunger rubber tip most of the large syringe manufacturing companies are using materials designed for: [URL='http://drugdeliverysystems.bd.com/products/prefillable-syringe-systems/add-ons-and-components/plunger-stoppers']BD Plunger Stoppers - BD[/URL] [LIST] [*][B][COLOR=rgb(184, 49, 47)]Biocompatibility; toxicology; and extractable, leachable, and pharmacopoeia compliance[/COLOR][/B] [/LIST] Let alone degradation from solvents. Depo-Testosterone whether 100 mg/ml or 200 mg/ml strength contains 9.45 mg of benzoyl alcohol per ml of oily solution which is not a lot.....definitely not enough to degrade the plunger stopper (rubber). Most preloading their syringes on trt are doing what.....a weeks worth at a time and even than on average most on trt are injecting 100-150 mg/week and out of that many are splitting total weekly dose into twice weekly (every 3.5 days) and to top it off many are injecting daily or EOD so how much benzoyl alcohol is there when preloading such low volumes of the oily solution (esterified testosterone). Highly doubtful the small amount of benzoyl alcohol is going to degrade the plunger stopper (rubber) over a 1-2 week period let alone even longer. Were all these members truly using big pharma or compounded injectable test? How many were using UGL/black market.....as who knows what % of benzoyl alcohol is used by [B][COLOR=rgb(184, 49, 47)]shady sources![/COLOR][/B] [/QUOTE]
