BioLean3 Reta Certificate of Analysis: What to Check
How BioLean3 Reta is verified: identity by mass, purity by HPLC and content per vial, plus what each line of its Certificate of Analysis should show.
What Published NAD+ Research Actually Examines
NAD+ is a coenzyme at the center of cellular energy and repair pathways. Here is what published laboratory research has examined, and what remains unknown.
What Is in a Tesamorelin Ipamorelin 5mg/5mg Blend Vial
A plain profile of our Tesamorelin / Ipamorelin 5mg/5mg blend: what is in the vial, how the two peptides differ in size, what published research examines, and how the blend is tested.
What Is Kisspeptin-10? The Shortest Active Kisspeptin
A plain profile of Kisspeptin-10 (KP-10, Metastin 45-54): what the peptide is, the receptor it targets, what researchers study it for, and how we verify it.
Ara-290, AOD-9604, and SS-31: Three Compounds That Went Through Real Drug Development
Quick answer: All three were pharmaceutical programs, not community discoveries. One completed Phase 2 trials with positive results and then ran out of company. One failed its pivotal trial outright and was abandoned in 2007. One spent two decades missing endpoints and then won an FDA approval in 2025. Knowing which is which tells you […]
Tesamorelin and Ipamorelin: Two Receptors, One Cell, and Why They Ship Together
Quick answer: They are not the same class of compound and they do not act at the same receptor. Tesamorelin is a growth-hormone-releasing hormone analog that binds the GHRH receptor. Ipamorelin is a growth hormone secretagogue that binds the ghrelin receptor, GHS-R1a. Both receptors sit on the same pituitary cell, which is the entire reason […]
How to Read a Peptide Vendor Review: What the Rankings Are Actually Measuring
Quick answer: Most “best peptide vendor” roundups are affiliate content. The ranking reflects which supplier pays the highest commission and runs the most organized affiliate program, not which supplier makes the cleanest material. This is not a conspiracy - it is a disclosed, legal business model. But it means the ranking is measuring something other […]
Thymosin Alpha-1, Thymulin, and Thymalin: Three Thymic Substances, Three Different Things
Quick answer: These three names get used interchangeably across the peptide market, and they should not be. Thymosin alpha-1 is a 28-amino-acid synthetic peptide. Thymulin is a 9-amino-acid synthetic peptide requiring zinc for activity. Thymalin is not a single peptide at all - it is a polypeptide complex extracted from calf thymus. Two […]
Epitalon and Semax: The Two Quietest Names on the FDA’s Peptide List
Quick answer: Both were recommended by the FDA’s advisory committee in July 2026, and both received a fraction of the coverage that BPC-157 and TB-500 did. They also share something more interesting than a vote: nearly their entire published record comes from a single national research tradition, which is exactly the criticism FDA staff raised […]
