I just ordered GLP-1 from Peptide Sciences. I was under the impression it can be used directly, but I'm getting a little confused by what might be posts about other peptides. I figure it's easier to ask directly since the more I search the less clear I am.

Does it need to be reconstituted/mixed or can it be used straight from the vial? I'm assuming because it's not a powder it doesn't need anything else to be done to it...

Also, what syringe gauge and length is recommended for subcutaneous?

Thanks in advance!
