Low unit doses: How to get the most accurate pin?

A smaller syringe like a 0.3 mL size helps with precision. I would also avoid such a low dose altogether and instead add more liquid during reconstitution so the volume becomes easier to measure.

I reach for 0.3 mL or 0.5 mL syringes when the dose is small, and I have also checked some pens for accuracy. Adding extra dilution sometimes moves the target into a better spot on the markings. The 0.3 mL ones I like now have smooth action and clear unit lines.

Has anyone compared those to the Easy Touch ones?

A 0.3 mL syringe can handle 0.08 mL reasonably well, but 0.015 mL becomes unreliable. For most peptides a few percent off does not change much, unlike the GLP compounds where even 10 percent can affect side effects. Anything that small really needs more dilution because even fine syringes vary by about 0.01 mL once bubbles are factored in.

Smaller syringes and extra dilution are the usual fixes, yet being off by a tiny bit will not cause problems. Keep the same reference point on the plunger each time and the results will stay consistent even if they are not perfectly exact.

Thanks everyone. I am going to try the 0.3 mL syringes together with higher dilution volumes. The brand suggestions are also helpful.

This is exactly the situation where pens become useful. Once you verify the pen delivers the correct amount, each dose stays very consistent.

I aim for an injection volume between 0.2 and 0.3 mL regardless of the actual dose, so I add enough BAC water to reach that target range.
