Honestly, even if it sucks for you, it’ll suck for 24 hours but it’s not horrible. Maybe a sleepless night and plenty of time to question your life choices. But you might want to just try a small pin without anything extra to see how you react to it. You may be one of the very blessed who doesn’t feel any burn or post-injection pain. (And don’t declare victory immediately. For me, the pain starts after a few hours.)
My recommendations in order for mitigating pain are:
1) First try the extra BAC method.
2) Add GHK-Basic. Anywhere from a 1:1 ratio or a 5:1 ratio (Cu:basic) will usually take care of the issue.
3) Add some epi/lido. The lido will only help with any immediate injection site burn or pain you get but the epi will help mitigate the histamine response that causes most of the issue.
I rotate using BPC, KPV, and TB4 anyway, but none were ever sufficient to mitigate the Cu problems. Some people swear by it. One thing I’ve learned through reading dozens of discussions about this is that everyone reacts differently. My recommendations above are listed in order of ease and cost effectiveness.
For me, #2 is the most effective and the only thing I do at this point. (No extra BAC. No more epi/lido anymore.) GHK-Basic can sometimes be hard to come by but it’s pretty readily available at the moment.
