@Paradox Yes, if you are going to let it warm up before taking it - You Cannot use pens.

@Bubba, the pens go down to 1 unit; not sure why you would want half a unit. Just double the back water when you reconstitute and use 1 unit. I think Jeff covered this on YouTube https://www.youtube.com/watch?v=geNpx5sJH3k. Basically, if you use as little as 1 unit, the little drip at the end of the needle contains more peptide than if you were using 5 units. I normally reconsitiute things so i'm doing 10units....Unless it's GHK-CU or something that stings, then maybe 20 units.

what was your order number. Chances are you got UV sterilized as we had a thousand of those come in at one point.

Thats a good question for @randy … I think he swaps them but when i was doing 4 peptides like bpc, TB, KPV, Ghk in all different pens i would use the same needle and toss it when done. Got the blend now so not needed. However i never mixed the needle with my RETA

I find it varies from batch to batch and vendor to vendor. My bride’s rat just started a new vial and found it burned. Mine started a vial from a different vendor and found it didn’t. I generally don’t have ISR’s anymore by injecting slowly. Was recommended by someone and oddly seems to work.

1 ml with 10mg (is it tested at 10mg or labeled 10mg, big difference) will give you 100 units = 10mg, so 10 units would be 1mg.
