KLOW injects - supposed to sting?

The sodium chloride BAC water for GHK-Cu sting reduction is worth trying before anything else - the standard BAC water formulation creates a localized reaction at the injection site that the saline-based version avoids for most people. Worth going through remaining vials with saline BAC as the carrier.

Nine weeks into my four-part blend protocol now. First vial, worried about the sting, so used 6ml of bacteriostatic water. Zero burn at all, so dropped to 3ml for the second vial and still no issues. Running a fine short-tip pen needle, dose straight from the fridge, don't feel a thing. My vials came in over-filled, landing around 60mg of the copper component, so running 10 units gets me 2mg, five days weekly.

That's basically my exact routine. Both come premixed commercially, the joint blend paired with a healing peptide, and the copper peptide paired with an anti-inflammatory one in what's marketed as a beauty combo, wish more places carried that second one.

Never had sting issues with the copper peptide since I always run it alongside the other one. Some initial bruising at the injection site, cleared up after about a week. 46 here, perimenopausal, thrilled with this routine. Skin's noticeably softer and firmer, especially around the eyes, neck, chest area. Glad the data suggests no cycling off is needed, so planning to run this continuously unless something changes that.

Like I mentioned before, here's what I run daily as part of the KLOW stack: 2.5mg GHK-CU, then 400mcg each of KPV, TB500, and BP-157.

I mix my own ghkcu with kpv rather than buying a premade blend. No stinging issues for me, had some early bruising, but that cleared up too about a month in.

Looked into combining several into one syringe, mostly to cut down on needles rather than protect my stomach lining. Honestly only the four-part blend ever causes any real reaction, gut seems fine, maybe even better now that I've slimmed down.
Comes premixed in 80mg vials, working out to roughly 2.5mg of the collagen peptide and 0.4mg each of the others based on the label info.

Seven weeks on Reta, ten pounds down so far, 0.5mg for the first three weeks, 1mg for the next three, now a month into 2mg and planning to hold there. Just did my very first KLOW injection, 80mg mixed with 3mL BAC, landing at 2.6mg or 10 units for the opening dose. Plan is sticking with 10 units for a week before bumping to 15, running that alongside the Reta for eight weeks total. Hoping it helps some old injuries heal and maybe tightens up any loose skin too.

* Also injecting the KLOW into the upper glute, and while I'd seen plenty of comments claiming that GHK-Cu component tends to sting, the shot itself was painless, just a mild dull throb afterward at the site. What I saw described as painful felt more like an annoying bug bite to me. I've got decent pain tolerance generally, but this really wasn't rough at all.
