Pure Health Peptides Review: Exact Purity Figures and Lab-Linked Reports at Curo

Why researchers choose Curo over Pure Health Peptides

Our purity figures are exact. Curo's Semax 10mg lot SEM10SR526 reads 99.6%, and our NAD+ lots NAD500SR526 and NAD1000SR526 read 99.9%. Pure Health's Semax report gives purity as ">99%", which tells you the lot passed a threshold but not where it landed.

Checking the lab's copy takes one click. Each published report in Curo's library has a Verify link to the lab's own copy. Pure Health's report files are on its own site. Its testing page says Ethos Analytics publishes them too, but the lab's lookup is a form that needs a company name and a sample ID.

Every order is protected. Curo replaces a parcel lost in transit or damaged by the carrier, at no charge and with nothing to add at checkout. Pure Health sells shipping insurance for $2.99 and says it is not responsible for lost shipments without it.

Payment options are public. Curo lists card, crypto with a 5% discount, Zelle and Cash App in our payment methods article. We found no payment list on Pure Health's pages before checkout.

Our blend kit costs less. The Curo KLOW kit is $124 for an 80mg vial, a 3 mL solution and a storage case. Pure Health lists its 80mg blend at $139.

Who Pure Health Peptides may suit

Pure Health sells capsules, liquids and topicals as well as vials, so it may suit a researcher who needs one of those formats. Curo sells vials and lab supplies.

Compare lots for a specific compound

Semax 10mg is a like-for-like match. Pure Health lot TUY-060326 was tested by Ethos Analytics, completed July 6, 2026: purity ">99%", endotoxin below 1.25 EU/mL, microbial pass. The report confirms identity by HPLC retention time against a reference standard, while Pure Health's testing page says identity is confirmed by HPLC-MS. Curo's lot SEM10SR526 was tested by BT Labs in May 2026: 99.6% purity, identity confirmed, endotoxin pass, with a Verify link. Our comparison of Semax and Selank covers the compound itself.

NAD+. Curo's NAD+ lots NAD500SR526 and NAD1000SR526 read 99.9%, each with an endotoxin pass. Our article on NAD+ trials and what they measure gives the research background.

At either store, match the batch number on the vial to the report. Our guide to verifying a COA against your lot shows the steps.

What we could not check

• Whether Ethos Analytics holds the same Semax report. Its lookup is a form, and we did not submit it.
• Payment methods at Pure Health's checkout. We did not start a checkout.
• Where its products are made. The site says batches are tested in the United States and names no manufacturer.
