Bacteriostatic water UK — FAQs

Where can I buy bacteriostatic water in the UK?
Peptides UK 4U holds bacteriostatic water in UK stock in 3ml vials at £3.49 and 10ml vials at £6.99, shipped the same day when ordered by 1pm, Monday to Friday.
Is bacteriostatic water the same as acetic acid water?
No. Acetic acid water is a dilute acidic diluent used only for a small number of peptides that will not fully dissolve in bacteriostatic water — specifically AOD-9604, Ipamorelin and Tesamorelin. For those, add roughly 0.5ml of acetic acid water first, then top up with bacteriostatic water. For every other peptide in our range, bacteriostatic water alone is the correct diluent.
Is bacteriostatic water legal to buy in the UK?
Bacteriostatic water is legal to buy and hold in the UK for laboratory research purposes. It is supplied here strictly for in vitro research use only — not for human or animal use.
