I prepare ten portions of five milligrams each out of a fifty milligram container for that compound. This way the injector device works for ten days. Recently I changed over to two milliliters of saline solution without any preservative. This results in tiny injection amounts around zero point two milliliters. That stopped the skin irritation issues. I haven't resumed the other peptide yet. The previous round left a large firm swelling in my leg, so I altered my approach. Avoiding low-salt preservative solutions now, using normal saline instead. The container gets used up quickly enough that contamination isn't a concern. Switching to an injector device fitted with a fine short needle. Avoiding larger needles and angled shallow insertions. Also stopping leg injections altogether. Lowering the amount per dose to two point five milligrams. My forty milligram containers provide sixteen portions. Splitting those across a pair of refill units, each holding eight portions of zero point three milliliters, using two point four milliliters of saline per unit. The low salt level causes issues with shots. The second compound might trigger sensitivity, so I'm trying to lessen that by using more liquid and salt to stop clumping. The salt also adjusts acidity toward neutral. I'm having fun with all this experimentation. It reminds me of my younger days experimenting with immune proteins and lab techniques, though I'd skip the radioactive part now.
