@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
-
@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. -
