Discussion: Nexaph
-
@peptidecritic main description of Nexaph says "rigorous third-party testing (identity, purity, and cleanliness checks)". I have been unable to find anything but COA's showing purity and identity. Have they changed their testing since your review or am I missing or just not looking in the right place for the cleanliness part of their COA's?
-
@jamiegallien I've only also ever seen purity, identity, weight (and occasionally, as in 5-amino-1mq not purity and identity because Janoshik does not offer it for 5-amino-1mq). That said I did send three vials of my 5-amino-1mq from them out for testing for identity, purity, weight, heavy metals, and sterility and it it came back clean (purity over 99.7%, weight in normal range of overfills, sterile and without heavy metals).

@PeptideEd Hi Ed, can you share where you send your vials to be tested for all those tests? Janoshik tests for purity for $300 but has add ons for quite a bit more. How much per vial for all those tests? I am very concerned about additives and endotoxins. Just trying to stay safe on this peptide journey. Thank you for your reply in advance!

I see Nexaph’s newest batch of MOTS-C returned from the lab at 98.5% purity. As a result, they are offering a 20% discount on it. What are your thoughts? Is a $50 discount on a kit worth 0.5% or so less purity? They said it’s in the “acceptable range” still… and I see most grey market vendors won’t offer refunds until it’s less than 98%. Just curious on how much of a difference this really is.

There is a lot of info out there around CoAs, what's acceptable, I found a site that broke it down well and explained it in simple Laymen's terms (imo).

Personally, I wouldn’t have a problem using that, having seen vials with similar results from other vendors and not having a problem with it. But that is my risk tolerance.

@Anthony So we are due for a refill of MOTS-C and we went too the site and saw the "discount" I went back and checked my past orders with them, one on Dec 26 and one on Feb 6 both of those orders were $145 the new batch with the discount is $150. This is a case of marking it up to mark it down. Still the best price I can find per MG though. I like Nexaph but as Randy says any site can turn bad at any time.
-
@anthony I was a little disappointed when I saw this. Don't get me wrong, I think Nexaph is handling this the right way, putting it front and center and adding a discount, and while they are probably correct that this is an acceptable level of purity... its a bit below my personal risk tolerance. The source of my disappointment is I would really like to order some MOTS-C from them
-
I'm looking for Tesamorelin, but their current batch doesn't have a CoA. Why would that be?
-
@billyshalom test results aren’t back yet. It’s post presale, but before the coa is in. Once the coa is in the price usually goes up.
-
@ricoadams so, the previous announcement there has been taken down. What I do see is that the 'Latest Results' link for COAs takes you to the 'Coming Soon page'. That situation happens pretty normally with Nexaph when they first get a batch in of something and Janoshik is backed up. So my guess is that they have gotten a new batch in.

I found it curious, after searching Nexaph on here that they had a lot of great reviews, all uploaded on Dec 1 2025. I really want to take advantage of this value & looking for confirmation to buy but the reviews look suspicious.

Do you have the reviews sorted differently? Because I didn't give reviews until I believe in Feb and March. The value is good, and the products are legit.

I use Nexaph for Tesa/Ipa blend and it is great., especially the price. I also bought CJC/Ipa blend for them. Those are the only 2 things I don’t buy from Puratek (because they don’t have them).
Nexaph has been easy to work with, they ship from inside of the USA and the product gets to me in 2 or 3 days tops…
Just know the vials come without labels. The box they come in has a QR code that links to the COA on Janoshink’s website. -

@commander I'd be curious your opinion wrt Tesa/Ipa vs CJC/Ipa

The problem is there is no real way to tell… Both my wife and I got Dexa scans the week before we started these peptides, she is switching to CKC/IPA and I am staying with Tesa/Ipa. She is still in better shape than I am in now. But how do you tell if one works better or not. I have a lot of visceral fat she does not.
So even with the Dexa scans it is hard to tell the difference between the 2. What we will be able to tell is if one works and one doesn’t, but not if one works better than the other…
