About PureSource Research

About PureSource Research

PureSource Research exists because the supply problem was real.

Compounds with decades — in some cases centuries — of documented research history were consistently available only through unreliable channels. Unclear sourcing. Inconsistent preparation. No batch documentation. No traceability.

For anyone serious about research quality, that wasn't good enough.

PureSource Research was built to fix that. Built around the principle that preparation quality matters.

"The standard is simple: know where it comes from, know how it was prepared, be able to prove both."

Every product is EU-sourced, prepared in small controlled batches, and released only with a full Certificate of Analysis. Every batch is traceable from raw material to finished product. Nothing ships without it.

The Compounds

🔵 Methylene Blue 4% Methylthioninium chloride · CAS 61-73-4 · USP Grade · EU Origin

First synthesised in 1876, methylene blue has accumulated one of the most extensive research histories of any synthetic compound — spanning mitochondrial biology, antimicrobial science, neuroprotection, redox chemistry, and antiparasitic research across 150 years of continuous study.

Mitochondrial & metabolic research Research has explored methylene blue's role as an alternative electron carrier within the mitochondrial respiratory chain, particularly in relation to impaired oxidative metabolism and cellular energy research. Atamna H, Kumar R. (2010). Protective role of methylene blue in Alzheimer's disease via mitochondria and cytochrome c oxidase. Journal of Alzheimer's Disease. PMID: 20847448 Rojas JC et al. (2012). Mechanisms of action of methylene blue in the brain. Progress in Neuroscience. PMID: 22172690

Antimicrobial research Methylene blue has been investigated as a photosensitiser in antimicrobial photodynamic therapy (aPDT), with activity studied against gram-positive and gram-negative bacteria, biofilm-forming organisms, and fungal species. Wainwright M et al. (1998). Phenothiazinium derivatives for photodynamic antimicrobial chemotherapy. Photochemistry and Photobiology. PMID: 9460820

Neuroprotective research MB has been investigated for neuroprotective properties in preclinical models, with research exploring its role in tau protein aggregation inhibition and oxidative stress reduction. Oz M et al. (2009). Cellular and molecular actions of Methylene Blue in the nervous system. Progress in Neurobiology. PMID: 19428958

Antiparasitic & antimalarial research Methylene blue was among the first synthetic compounds investigated in antimalarial research — studied by Paul Ehrlich as early as 1891 — and continues to be examined in this context.Guttmann P, Ehrlich P. (1891). Über die Wirkung des Methylenblau bei Malaria. Berliner Klinische Wochenschrift.

PureSource specification: USP grade · Elemental impurity tested (As, Pb, Cd, Hg) · 4% w/v · Distilled water · Plant-derived vegetable glycerin · No alcohol · No formaldehyde · No preservatives · Cobalt blue glass · Full COA every batch

🟤 Lugol's Iodine 3% Iodine/Potassium Iodide Solution · EU Origin · No Additives

In continuous documented use since 1829. Prepared from elemental iodine (I₂) and potassium iodide (KI) in purified water — the original formulation, largely unchanged across nearly 200 years of research application.

Thyroid & endocrine research Iodine is essential for thyroid hormone synthesis and the relationship between iodine availability and thyroid function is one of the most extensively documented areas in endocrine research. Zimmermann MB. (2009). Iodine deficiency. Endocrine Reviews. PMID: 19460960

Antimicrobial research Iodine is one of the oldest and most studied broad-spectrum antimicrobial agents. Its activity against bacteria, viruses, fungi, and spores has been documented across decades of research. Gottardi W. (1999). Iodine and disinfection: theoretical study on mode of action, efficiency, stability, and analytical aspects in the aqueous system. Archives of Pharmacy. PMID: 10546892

Biofilm research Iodine-based compounds have been investigated for activity against biofilm-forming organisms — an active area of study in microbiology research.

PureSource specification: 3.0% w/v I₂ · ~1.5mg per drop · EU origin · ISO 9001 certified supplier · Heavy metal tested · Zero additives · Zero alcohol · Zero preservatives · Amber glass dropper · Full COA every batch

🌲 Pure Gum Spirits of Turpentine Pinus elliottii Oleoresin · Steam-Distilled · EU Origin · Terpene Profile Verified

Steam-distilled from Pinus elliottii oleoresin. One of the longest-documented botanical compounds in research history — with applications spanning chemistry, microbiology, and materials science across centuries of study.

Terpene chemistry & research The active constituents are monoterpenes — primarily α-pinene and β-pinene. Both have been investigated across peer-reviewed research for their biological and chemical properties.

α-Pinene has been studied for antimicrobial properties, anti-inflammatory mechanisms, and acetylcholinesterase inhibition. Salehi B et al. (2019). Promising Biological Activities of Pinene. Journal of Agricultural and Food Chemistry. PMID: 31397186

β-Pinene has been investigated for antimicrobial and antifungal properties in research models. Leite AM et al. (2007). Inhibitory effect of beta-pinene on the growth of some food-related bacteria. Brazilian Journal of Pharmacognosy.

The documentation gap The dominant US-sourced brand in this category provides no published terpene profile data and no Certificate of Analysis. Researchers have no way to verify composition, batch consistency, or sourcing integrity.

PureSource Gum Turpentine provides both. Terpene profile verified by chromatography. COA on every batch. EU origin, Portugal. Pinus elliottii. Fully documented.

Why source species matters Terpene profiles vary significantly between pine species and geographic sources. α-Pinene and β-Pinene ratios differ meaningfully between Pinus elliottii, Pinus palustris, and other species. For research requiring compositional consistency, documented sourcing is not optional — it is the baseline requirement.

PureSource specification: Pinus elliottii oleoresin · Steam-distilled · EU origin (Portugal) · α-Pinene 45–50% · β-Pinene 35–40% · No additives · No solvents · Green glass · Full COA every batch · CAS 8006-64-2

Documentation Standard

Every batch ships with a Certificate of Analysis. COAs are published on each product page and accessible via QR code on the label. Batch traceability is maintained from raw material to finished product.

This is not standard practice in this market. At PureSource Research, it is the minimum acceptable standard.

What PureSource Research is: An Ireland-registered research-use supplier. Founder-led. Small batch. EU origin. COA verified.

What PureSource Research is not: A supplement brand. A wellness company. A medical supplier. A vendor making health claims.

All products are supplied for research purposes only.

Clean inputs. Honest preparation. Consistent output.
