Using 525mg a week. It's amazing I'm on week 10 now. Like milder tren sprinkle with a bit of masr. Or like stronger primo but with less hairloss and less spots(personal issue with DHTs) I brew at 75mg/ml. I pin one ml a day through an insulin pin. Hence the 525mg I use 2%BA 24%BB rest mig840. EO doesnt agree with me. Always get big hard painful lumps. Pip is random. Honestly I have had pip turn up a 5 days later and then in some spots its maybe a few hours. With that recipe I have never had it crash but it's also quite warm and humid here. If it is not that impressive then you would be underwhelmed by primo at a greater cost and pinning more mg to get less out of it. To me it's an absolute no-brainer.
