Discussion: Blackline Scientific
-
So all within the span of ONE DAY we have a new vendor called Blackline Scientific pop up here applying to become a vendor on this website called PEPTIDE CRITIC and does not seem to understand that the users here are well informed and do due diligence on what we buy, where we buy, and who did the testing.
Blackline Scientific then hijacks a couple of threads to try to market and promote his own site, yet doesn’t even read the threads he hijacks, to know that we don’t consider Freedom Diagnostics to be a reputable lab around here. He then claims in those threads that ALL of the batches of peptides they sell all have been tested by Freedom and have COAs for each every one of them.
Then Blackline Scientific gets called out for their many lies. Not having COAs for over a dozen peptides they have available for purchase right now. For using other companies COAs. For posting COAs that are not even from Freedom but other labs with other companies names on them.
When pressed on this they double down saying they are not hiding anything and that their wholesaler did the testing and that this is how it works and a nothing burger. They refused to accept that this is not how it works just because you buy wholesale and then sell retail. They refused to answer why they are selling peptides that have no COAs at all and that customers are supposed to just accept what the label on the vial says it is.
While Randy is posting proof of their lies, they start scrubbing the site but it’s too late for them.
And now they defend using Soma Chemicals COA for an item they sell yet the COA is from September 2025 and says batch unknown!?!?!?
You can’t make this level of stupidity and comedy up. And this is all within a span of ONE DAY

I won’t be shocked to find out that they just put up the website two days ago.
Blackline Scientific is either really really stupid or is really really dangerous. No one should risk their safety by purchasing anything from these people. Their incompetence or their scamming, defrauding and misleading ways is huge risk for anyone who buys anything from them.
100% AVOID BlacklineScientific.com

@Canineriot hey now. we like to keep them talking

@Randy Lol! Sorry, I got emotional

Among what’s already been discussed, I’d like to know how they allegedly supply med spas?
How is a medical professional able to purchase and resell or administer RUO peptides?

@jdot You will find people on Reddit posting pics of medspa's prefilled UNMARKED INSULIN NOODLES of Reta for $500.
Reddit was also my intro to peptides but I waited out to find right forums and sources.

That is what got me into this space in the first place. My wife was getting 6mg a week of reta at a med spa for $225 a week. That was unsustainable so I started researching peptides and how to get them cheaper. Now I also am in on peps and get hers as well.

@jdot they hand them a bag. Do you know how many medspa's offer reta/bpc/epithalon etc?
Its a DIRTY little secret.

@pep_researcher Same here. MHC was my first Reta purchase, then Reddit lead me right into the grey forums.
I think it’s wild that legitimate medical establishments are supplying and administering grey market peps. -

@pep_researcher I had a customer I used to sell to do that very thing! I stopped selling to her because I considered her practices extremely risky and I didn't want my company name tied to hers in any way.
Now she's sourcing directly from the grey market and not testing ANYTHING becausev she says the vendor she buys from says that their product is good.
The worst part? People buy from her. She operates a so-called "spa" out of her home. Her customers just take their little metallic pouches of pre-fills and go on their merry way. No labels. No COAs. No nothing.

Well this is all kind of horrifying.

@angelad I know and completely believe this because there was a conviction of a medspa owner last year or before because her customer ended up in ER (or died). You will find the exact news online.
