Any wild stories from your own experience, or crazy reports on Discord?

Like big differences in fill or purity for vials supposedly from the same batch?

In other words, group testing that gives more questions than answers?

Just curious since I do group buys as my method of third-party testing. And I've only seen kosher results, including with the group test results people post elsewhere.

Perfect timing, since @chmuse just posted a good example of variation in overfill:

 
There's this one from Nexaph. Jano was available at time of purchase so informed buyers knew they were getting a good deal. Uniformed buyers were probably online complaining about side effects or claiming their product was 🔥 over other vendor's Cagri. (overdosing).

Doesn't really fit your topic since the tested vials are consistent but notable none the less... 29% overfill on something like Cagri is significant! 🤢

Intra-Batch variables would be more disturbing. With this recent Nexaph disclosure to be safe I guess everyone should underdose if they're forced to keep it.

GYC just had a batch of MT1 that went to a GB where one vial tested just under 3mg and the other 10mg on the dot. Was supposed to be a 10mg batch. (They're following up with more vials at another lab. I don't want to post their COA or the name of the GB without permission.)

Don't remember the vendor for sure so I don't want to call them out by name, but at the end of April there were vials of ghk-cu that were testing 2-3 times the expected fill.

In April there were t30's sent out that tested as t60's.

A group test COA of double-filled GHK-Cu from SRY is in my signature, posted by @Peloma.

For posterity:

Ghk-cu 50mg overfill from SRY... I see this as a win! Be careful out there, folks. Check your stuff and then check again. You could have a bad day...

Headed home just to see if I hit the ghk jackpot... 😆

Another reminder not to try a higher dose when starting a new kit:

I was on 8mg. But because that new kit from GYC was 50mg I increased to 10mg the morning before the hiccups started. After the hiccups started I joined a test group and we sent 3 vials to Jano. All three were around 58mg each. So in reality I took almost 12mg the day before my nightmare began. So maybe going from 8 to 12 caused the issues.

I saw it as a win, but I can see where it could be an issue.

I was taking 3.4mg pins of the stuff when I thought I was at 1.7. I carried on through the protocol, and am honestly probably going to stick to a 3mg protocol. I love the mood altering and anti-inflammatory properties of GHK-CU by itself.

It was SRY. Their GHK-Cu has been consistently massively overfilled. The 50mg kit I bought in the beginning of the year tested between 71 - 73mg.
 
Over 50 percent overfill from TFC's T30 from the US warehouse (first two vials are China, last two are US warehouse):

I don't know if this is the same incident cuz I thought tfc had overfill in May. Good Ole SRY had 100% overfill in April it wasn't tirz ret or sema...
 
I’m not on Reta, so it doesn’t concern me directly. But my favorite vendor recently reported significant intra-batch variability of their most recent Reta batch.

Someone in another forum said a variance of 20% between vials of the same batch is acceptable, even with T30mg vials, which would allow for 30s and 36s within the same batch. But to me, it’s gotta be less than 4% between vials of the same batch for it to feel safe.
