Finally been waiting to see who’s been running his test c 250 sounds good probably will order a 20mlI've been running his Test Cyp 250 ad EQ 300 with no issues.
Also pinned his DHB 100 mixed 50/50 with Test Cyp 250 twice without any PIP or discomfort.
YMMV but for me it's been 100% so far but I do take my sterilization seriously. I draw with a 23 and inject with a 1" 25 in my right quad exclusively.
GK Primo 200 never gave me any issues either and I've went through many many vials of it. I have some Primal Primo 100 on hand but would like to try his 200 to compare it to. When it comes back in stock I'll try to grab a few vials to try out.
