Test e gives you pip either way
Test c look at what ugl offers and do the same concentration. Usually is 200mg test c. Is a reason why you don't see at 300 mg test c. It's prone to crash also
When I say 300 mg for long ester that was with deca,eq. Those at 300mg are pip free. Not with everything. Same with primo. Do 200mg not 300mg.
If you use concentration that are considered normal you will not have pip problems
Normal is:test a,npp,test p,primo a-100 mg. Long ester: test c,primo,tren e,mast e-200mg and deca,eq 300 mg. Use those concentration with 2/20 or 2/18 and you will not have pip problems.
Some you can make higher concentration but if you don't look for that is no need to do so. Or some had brew some higher concerns with no pip but if you don't look for that no need to bother with that
No need for any recipe. You had one universal one and concentration use what is considered normal,popular and you see that every ugl offers and that's it. For some you can use lower % of bb but if it's not broken then don't fix it
