Oils too?

[noctivagant]

My apologies if this is too off-topic but can these pen vials also be used for oils as well as peptides? I've gotten increasingly frustrated with trying to not have a lot of waste or incorrect dose on items with very low amount of units, using syringes. While with water, it's easy to add more, it's not so easy for me to get supplies to dilute a oil, and I only need 2 units.

I will defer to those who are using pens for T or thick peptides, but I think the main challenge will be the viscosity of the oil, needle gauges, and whether the spring in the pen is sufficient to push the oil.

Droplet 29g 12mm pen needles may be the go to without spending a ton of money for specialty needles of greater length and bigger bore size.
