Great results on the peptides as usual.
Most of my Tesamorelin light blue tops don't have vacuum.
Light, heat, oxygen are the three things that degrade lyophilized peptides. I'm not concerned much about sterility, they seem to be sealed (they hold pressure), but no vacuum means they'll degrade faster.
In the spirit of continuous improvement, and I don't know if you package this in house or you get it from an external supplier, but it's no good for you to have stock that degrades faster than it should, please look into this to make sure it doesn't happen again.
I've heard from others who have the same issue, and some with HGH vials without vacuum as well, so maybe a coincidence or something's wrong in your packaging process.
Anyway, I'm not looking for a replacement over this, I'm happy with the quality otherwise, Since getting a cryofreezer I wanted to pick up 30 kits, but I can't from this batch since no vacuum isn't great for long term storage.
Go crack someone's head, because QSC keeps raising the bar on peptide quality, I'd say the best among UGLs. Don't let this one simple part of the process spoil it.

All the tesamorelin batchs are from July/August and earlier.
It is possible that it was the reason why they were degraded in the testing results.
The HGH vials have vaccum.
Peptides and HGH are not produced by same engineer.
In general vaccum is done for every batch of every peptides and HGH, but it can happen that some vials can lack of vaccum, which is a completely normal thing in the production process, but the majority of the batch is vaccum.

I thought the HGH wasn't a widespread issue or we would've seen comments from others. But so far 9/10 vials of this batch of Tesa don't have vacuum and in this instance, for this batch, it's definitely common from the messages I got.
Again, the quality is great, it's working like it should, but I know how you crack the whip over there so I wanted to make sure you were aware of it.
Oil drama aside, based on quality and value, I don't see how anyone could rationalize using another source for peptides.

The quality of the peptides has improved a lot since the summer (for instance the tesa batchs), I had some episodes of GB reships you all know about, and it's no longer an issue now, as soon as I clean up the current tesa stock, the new batch I expect it to be much better.
The tesa/ipa blend is part of the new batchs, and I can advise it for the ones who want a better quality tesa blend

At the risk of being accused of shilling, and I know this is strictly business not a humanitarian pursuit, I appreciate the work you've done to make high quality peptides available at great prices.
The relentless testing, continually adding new products, responding to feedback, makes QSC a real asset to the peptide using communities.
It's no exaggeration to say that your efforts have directly helped improve the health and quality of life for countless people.

Well said @Ghoul
@Qingdao Sigma Chemicals deca and also in the future EQ were not planned to be made heavier in terms of dosage?
Any updates on this?

It got lost on the way to Jano. I have to send another sample when holidays are over in my country.
