Real peptides. Compounded in the USA.
MaxSpan supplies research-grade peptides that are compounded by state-licensed US pharmacies, overseen by licensed physicians and a medical director, and lot-certified before they ship. Not an overseas lab.
What we do
We supply research-grade peptides that are compounded inside the United States by state-licensed compounding pharmacies, overseen by a network of licensed physicians and a medical director, independently assayed on every lot, and shipped the same business day. The certificate for your exact lot travels in the carton.
That combination is the whole competitive advantage. Most of this market is product from a lab overseas with paperwork that belongs to a different batch. Ours is not.
Compounded in the United States
Every compound is prepared by a US state-licensed compounding pharmacy operating under state board of pharmacy oversight and USP standards for sterile preparation. Those facilities are inspected and on record. Nothing is imported in bulk, repackaged, or drop-shipped from a warehouse we have never seen.
Partner pharmacies: [NEED FROM TYLER — pharmacy names and licensing states]
Physician network and medical director
Sourcing, quality thresholds and lot release are overseen by a network of licensed physicians and a medical director. That oversight is what makes the analytical standard a standard rather than a marketing line.
Medical director: [NEED FROM TYLER — name, credentials, state of licensure]
Research use only
Peptides in this category are not FDA-approved drugs, and we say so plainly. Everything we supply is labelled and sold for research use. We do not advise on dosing, administration, or human or animal use, and we will not if asked.
Why the documentation matters
Most of this market runs on assertion. A vendor states a purity figure, and the buyer has no mechanism to check it. Certificates circulate that belong to different batches, to different compounds, or to no test at all.
The only meaningful answer is a certificate tied to a lot ID, from a named third-party laboratory, that a buyer can request before purchase. That is what we built, and it is the reason the lot lookup sits on the homepage rather than buried in a support article.
What we will not do
- Release a lot that failed analysis, or rework it into a later batch
- Issue a certificate that is not tied to a specific lot ID
- Publish an assay figure we have not received from a laboratory
- Advise on dosing, protocols, administration, or human or animal use
- Sell to anyone who is not a qualified researcher aged 21 or over
Who we sell to
Qualified researchers, laboratories and institutions purchasing materials for in vitro research. Placing an order is a representation that you meet that description and that you understand these materials are not for human or animal consumption.
If you are looking for a clinical service, this is not one, and we cannot refer you to one.
