Research Reference
A plain-language reference for the arithmetic behind reconstituting a lyophilized peptide vial: mass over volume, what a U-100 syringe's unit markings actually measure, and where the common errors come from.
Research Reference
Reading a COA is step one. This guide covers independent verification: matching lot numbers, confirming the lab is genuinely third-party, using lab verification portals, and checking a report for internal consistency. Research use only.
Quality & Testing
"Where can I actually buy research peptides?" is the most-asked question in this space in 2026 — and after the year the industry has had, it deserves a more careful answer than a list of names. Peptide Sciences shut down in March. Amino Asylum was raided. At least
Quality & Testing
2026 has thinned the herd. Peptide Sciences shut down in March, Amino Asylum was raided by the FDA, and at least seven other vendors closed through 2025. If your usual source disappeared, you are not alone — and you are right to be careful about where you move next. Buying a
Mechanism Explainers
GHK-Cu is one of the most-studied small peptides in the research literature, which also makes it one of the most misunderstood outside of it. This overview walks through what GHK-Cu actually is, where it comes from, and what researchers have examined it for — strictly as a research-
Mechanism Explainers
5-Amino-1MQ has been getting attention lately as an oral research compound in a field dominated by injectables, and the search results for it are a mess — half of them are about something else entirely. This is a clean, neutral overview of what 5-Amino-1MQ actually is and
Mechanism Explainers
GHK-Cu is one of the fastest-rising peptides in the research conversation right now, and the question that comes up more than any other is: injection or topical? Most of what ranks for that question is a vendor arguing for whichever format they happen to sell. This is a
Storage & Handling
Your package sat on the porch for two days in 90-degree heat. Or the ice pack showed up warm and useless. Now you're staring at the vial wondering if the material is ruined. It's one of the most common questions in research-peptide handling — and
Research Comparisons
CJC-1295 and Tesamorelin come up together constantly in growth-hormone-axis research, and for a good reason: both are analogs of growth-hormone-releasing hormone (GHRH). That shared classification is exactly why researchers compare them — and also why they're easy to confuse. This overview lays out how
Plain-language summaries of peptide research — new articles as they publish.
CJC-1295 is one of the more frequently referenced peptides in growth-hormone research, and also one of the more commonly misunderstood — largely because several closely related versions circulate under similar names. This overview clarifies what CJC-1295 is, how the variants differ, and what the research literature actually examines,
BPC-157 and TB-500 are two of the most frequently studied peptides in tissue-repair and recovery research, and they're often mentioned in the same breath. If you're trying to understand how they differ as research compounds — and why researchers so often study them side
The research peptide market has been reshaped in the last two years. Long-standing suppliers have shut down or been forced offline, and buyers who trusted a single source for years suddenly find themselves starting over. If you're re-evaluating where to source research materials in 2026, this
Few molecules are as fundamental to biology — or as central to modern longevity research — as NAD+. Unlike the synthetic peptides often discussed in research circles, NAD+ is a coenzyme found in every living cell, essential to how cells produce energy. This overview covers what NAD+ is, where the science came
A peptide that tested at 99% purity on its Certificate of Analysis can still degrade in your own fridge if it's stored wrong. Storage is chemistry, not guesswork — and the rules are simple once you understand why peptides break down. This guide covers how to keep lyophilized and
A Certificate of Analysis is the single most useful document for judging a research peptide — and one of the most misread. A COA is where a vague brand claim like "99% pure" either gets backed by data or falls apart. This guide explains, in plain terms, what each
Most peptides discussed in research circles are either hormones, hormone fragments, or synthetic analogs of them. MOTS-c is something different — a peptide encoded not in the cell's main genome but inside the mitochondria, the organelles that produce a cell's energy. That unusual origin is what
Semax and Selank are almost always mentioned in the same breath — two synthetic peptides from the same Russian research program, both stabilized the same way, both studied for the nervous system. That shared origin is exactly why they get confused. But they are different molecules, built from different natural precursors,
Selank is the sister compound to Semax — developed by the same Russian research group, built on the same design principle, but derived from an entirely different natural molecule and studied for a different set of questions. This overview covers what Selank is, where it came from, what the published literature
Semax is one of the most-studied synthetic peptides to come out of Russian neuropeptide research, yet it remains largely unknown in the West. This overview covers what Semax is, where it came from, what the published literature has actually examined, and how researchers evaluate the quality of a reference
TL;DR: "99% pure" and "research-grade" are common phrases in the peptide space, and they're often read as a stamp of safety. But purity and safety are different questions. A certificate of analysis (COA) tells you what a compound is and how much
TL;DR: In 2023, The New England Journal of Medicine published a Phase 2 randomized controlled trial of retatrutide, an investigational triple-receptor agonist, in adults with obesity. Rather than just report the result, this article uses that paper as a worked example of how to read a clinical study
