Other user was complaining about 36 black tops which I have from around the same time, was assured there fine but I'm not testing a single batch not worth it.
I have the 24 black tops from HYB as well and bought domestic growth guys 45 purple caps and been rotating daily to see any difference.
Honestly the only difference I notice is the 36 black top cause my heart rate to go up a bit and my face flushes a bit for 5-15 minutes ( 10 ui )
I tried adding more bac water like Ghoul suggested and same effect, last night I did 5 - 5 - 5 from all 3 seperately 15 minutes apart and same thing happened with the black tops and nothing from the other 2.
No idea what this means, weight went up 2 pounds though which is fairly normal for GH dose increase for me since I was using 15 instead of 10 pre bed.
If you have a lot of the black tops and bought around mid Oct might be smart to get them tested, I'm not though.
