@beachfun Thats really weird.
Copper is normally best in the high Glute area, Ive done a KLOW blend up there for a while and straight GHK.
I do have a system that I reconstitute the blend with 2ml bac then I preload a few syringes with around 20ml BAC.
On the day of the shot I add the Blend to the preloaded BAC syringe and I let it sit for 30min to get room temp.
I use a 8mm and if you use less it tends to BUMP up.
Other blends I havent done but the KPV, BPC and TB should be a very good blend to do anywere especially in the belly.
Maybe you got a bad batch.
Nowadays I filter all my peptides, I leave the vial and bac to room temp before mixing, and I havent had any problems with blends.
@randy can disagree but Ive seen many test that Blends dont degrade in short periods and if you mix them all together in 1 syringe, it doesnt degreade either.
