Using A Filtered Needle

Whether you research peptides or are a biohacking beauty, knowing how to use a filtered needle is important in harm reduction. I’m demonstrating the use with Laennec and its glass ampule, but consider it an option for unknown sterility research needs as well.

Laennec can be found at Meamo Shop, https://meamoshop.com/injections/laennec-50-ampoules/ use Elle15 to save you 15% or more.
