Hey all

Filtered my very first vial today and immediately did something dumb: pushed the peptide back into the old vial rather than a fresh one. Caught it, then re-filtered into a new vial. Is that acceptable, or should this batch go in the bin? Sorry if this is obvious to everyone.

Nothing to worry about...
 
All good. That just means it got filtered twice. 🙂. Provided the end product went through a sterile vial or cartridge. One more thing - was the filter fresh on that last pass?

That 100% didn't occur to me at all 😬
 
The key: keep the filter in the flow only while solution is being pushed out of the syringe. Never pull solution into the syringe through a filter. That's my habit anyway
 
Not ideal, sure - yet even had you left it sitting in the original vial, you've still done better than skipping filtration entirely, which sadly is what the overwhelming majority of underground lab peptide users end up doing...

Oof. Alright then - which empty sterile vials are you using?

At $2 a piece these use the same anti-delamination technology as Corning Valor, more or less.

Also worth saying: glass is anything but inert. The cheapest stuff can leach industrial chemicals you don't want straight into solution. These ones meet USP (US pharma) specs - particulate, endotoxin free, that lot.

The second box ticked is a Teflon coated stopper that carries USP approval. I'd rather not have the cocktail of carcinogens and endocrine disruptors from those recycled Chinese truck-tyre stoppers seeping into a liquid I inject on a schedule.
