Tesamorelin and gray-market BAC water: does pH matter?

Hi everyone,

I recently chatted with a vendor who has been around this forum for a long time. I asked him about his t e s a and BAC water. For TESA, he said to use only Hospira b a c water or sterile water, because the pH of his BAC water is slightly different. Has anyone here used gray market BAC water alongside their Tessa and gotten good results?

Is that the usual rule, or does it just apply to this particular vendor's BAC water? So far I have only used gray market BAC water that came from a vendor with my RETA, and I have not run into any problems. Thanks all
 
Just my 2cts.

BAC water from a vendor, Amazon, a peptide web shop, or similar sources should NEVER be used.

You can either buy Hospira or make it yourself with USP grade SWFI (B.Braun, Aqua Sterop, etc.) plus Benzyl Alcohol.

At this point, the issue could be your BAC, your Tesa, or both, and there is no way to know unless both have been tested.
 
Don’t use bac water from vendors. Eventually it will cause problems.

When people say their compound seems off after reconstitution, in most cases the bac water is what’s causing it.
 
Tesa, just like ipamorelin, reacts more strongly to pH shifts than most other peptides do. That means vendor BAC tends to be harsher on it.

Peptide Test currently has Hospira in stock, priced at $15 per vial:

Once you have Hospira BAC on hand, using a vent needle is the better approach. The reason, as you probably already know, is that a vent needle keeps the vacuum in the vial from pushing out a forceful stream of BAC. Still, I frequently skip the vent needle myself.
 
Just so you know, I haven't run into any problems myself. I'm only trying to work out whether the explanation a vendor gave me holds up — and it certainly seems to.

Watching a few Janoshik clips about vendor BAC would be worthwhile, in my view.

According to him, lots of them fail testing for various causes — including sterility, Endos, and no bacteriostatic alcohol at all, just to list some.

Given how much time, work, and money these peps demand, my own stance is that spending a few extra nickels per dose on the quality product makes sense, if only for that reason.

With peps that are pH sensitive, there is all the more cause to do so.
 
Also, tesa isn't a low-cost peptide on its own, and on top of that you'd ideally want IGF-1 bloodwork plus fasting insulin, fasting glucose, and/or A1c. So if saving money is the goal, tesa isn't the right pick regardless. Oral creatine would serve you better, and arguably it's more effective too, unless your IGF-1 is low.

As for me, my own limited time with GH peptides covers HGH and hexarelin. Hex appealed to me more because of its safety profile and the fasting routine I built around it. Whether those GH peptides actually helped me over such a brief period, I can't say. I've been intending to start tesa any day now (going on months) after already buying some. My plan is just 1 mg per day of tesa.

My IGF-1 baseline sits around 190, though I've only ever checked baseline because my cycles have been so short and quick. I went ahead and bought the follow-up tests in advance through Fitomics, roughly $14 for IGF-1 at Labcorp, on top of the $30 membership fee that I cancel immediately. Goodlabs is another route, as is Dirt Cheap Labs. For fasting insulin, Quest comes in cheaper than Labcorp. With IGF-1, it's the reverse.
 
I’ve run into the same problem — when vendor BAC is combined with TESA and then mixed with IPA, it clumps or turns to gel. After trying out various setups by trial and error, the reconstitution approach I now favor is 1/3 buffered saline for the initial reconstitution + 2/3 BAC for additional dilution, so that the chance of low BAC pH is reduced while still keeping some antimicrobial strength. Don’t @ me, It works for me.🥼
 
Thanks everyone, I wasn't aware of this. The BAC I've been using has worked fine for my RETA. My hesitation was around 30 ml bottles—following the 28-day rule, a lot would go to waste. But from what I gather, TESA is a different situation since it's dosed so often. On another note, I just placed an order for five bottles of hospira from the peptide test site mentioned above. Appreciate the assistance.
 
The BAC water from that vendor is what I use too, and it's been several months with nothing going wrong. That said, I've seen vials such as CP turn into a gel when the pH runs high.

Besides the vendor's Bac water, I also have Genentech's pharmaceutical-grade Bac water on hand. With GLP-1s, I simply go with the vendor's Bac water once I've checked the pH; with other peptides, I'll only use the vendor's if I'm sure about the pH and the other factors, and if not, I reach for Genentech's. So far, no issues have come up.
