Ratings are our editors’ scores from one public rubric (COA, price per mg, delivery, returns, vendor reputation). They are not customer reviews. How we review
Peptide God lists its Selank + Semax Blend at $59.95 (US dollars), $10 more than its N-Acetyl Semax Amidate on its own at $49.95. For UK readers interested in selank, the selank semax blend is the only way that vendor sells selank at all, so it is worth knowing exactly what the listing tells you and what it leaves out.
The product is described as mentioned above. Semax and selank themselves are unlicensed in the UK, and this mixture is labelled research use only. We have not tested it, and we cannot confirm what is in it apart from what the vendor states.
The listing is short. Here is everything our sources hold about it.

Equally significant is what is not there: no information given about either peptide, no specification of the laboratory conducting tests and no production batch details.
The vendor refers to this stack as a very popular nootropic research in the form of an all-in-one solution. Those are words used by the vendor, not any proof of effectiveness in humans.
The proportion between the two substances is predetermined by the seller, and there is no mention of it in our listings. It is not possible to alter the proportion of the compounds, and you will need to check the label or seller's documentation in order to find out the content of the bottle.
If a supplier fails to respond to these queries, this indicates something about the product. A predetermined ratio isn’t a disadvantage in and of itself, an undefined one, however, is a shortcoming, since no comparison can be made to anything, including the vendor's own N-Acetyl Semax Amidate.
Safety is significant too. If so, whatever has happened, first off, every physician is going to want to know the specific substance contained within your product, meaning a vague 'selank semax mixture' will not suffice.
“Lab-tested” refers to the claim by the seller that the item has undergone testing, with no other specifics provided. Our notes do not mention the individuals responsible for the testing, the method of testing, or the definition of published results, aside from stating the product was tested.
A proper certificate for a blend of selank semax with two agents should state the identity of each agent and contain its results. A single purity statement with regards to a blend will not be able to show if the proportions are right. The same position is correct for the MHRA since the “for research use only” label does not mean the product conforms with the medical standards.
Selank is not being offered as a standalone product by our supplier. The only form in which it is provided is as part of the compound together with N-Acetyl Semax Amidate which has its own listing. Hence, we would like to clarify that we do not imply that a single-peptide product of selank is available.
The difference in the cost is not substantial. The combination is priced extra $10 compared to N-Acetyl Semax Amidate; thus, people cannot call the Selank Semax combination a cheap option for acquiring Selank from this supplier.
For a buyer that is a real trade-off. You cannot study selank on its own with this product, and you pay for a second peptide whether you want it or not. If your interest is semax only, the separate N-Acetyl Semax Amidate listing, covered on our semax page, is the closer fit. The selank vs semax page sets out how the two compounds differ.
The vendor's operations are in the US and the currency used for the pricing is US dollars. We have not checked if it ships to the UK. Please verify that on its website.
Selank and semax are both unlicensed in the UK and sold as research compounds; see the selank UK guide for the legal position.
