Sildenafil Citrate: Oral Research Format for Laboratory Research
Sildenafil Citrate 100 mg Tablets | 50 Tablets is an oral-format research product from VendPeptides: Sildenafil Citrate, PDE5 inhibitor small molecule, supplied for laboratory research. Every lot ships against an independent third-party certificate of analysis matched to the batch number on the vial, and the certificate — not this page — is the source of purity, identity and net-content values for the material you receive.
This page sets out what the listing states, what the published literature says about Sildenafil Citrate, how the material is handled in a laboratory, and how it compares with related compounds in our Research Supplies & Ancillaries collection. For research purposes only. Not for human consumption.
What Is Sildenafil Citrate?
Sildenafil citrate is a phosphodiesterase-5 inhibitor small molecule supplied as 100 mg tablets, 50 per bottle, as an oral-format research product.
It is a well-characterised pharmacological tool in smooth-muscle and cGMP-signalling research.

Research Applications of Sildenafil Citrate
The published research on Sildenafil Citrate is summarised below by application area. These are contexts in which the compound appears in the literature, not claims about outcomes; the model, the endpoint and the concentration belong to the researcher's protocol.
PDE isoform assays
Selectivity panels across PDE1-11.
cGMP signalling models
Smooth-muscle and endothelial culture.
How Sildenafil Citrate Works: Mechanism in the Published Literature
Inhibits PDE5, raising cGMP in smooth-muscle and other PDE5-expressing cells. Standard reference inhibitor in PDE isoform-selectivity assays.
Handling and Storage of Sildenafil Citrate
Tablet format; store dry.
This is an oral-format research product. Excipients, coating and tablet or capsule weight are not stated on the listing; they belong to the batch documentation. No quantity for use in any organism is published here.
Safety, Compliance and Precautions
Research use only
For research purposes only. Not for human consumption. An oral-format research product is still a research chemical, not a supplement or a drug. It must not be administered to humans or animals.
No dose is published, anywhere
The listing states tablet or capsule strength and count. Nothing on this page or this site states an amount for use in any organism.
Laboratory handling
Keep the container sealed and dry; handle with gloves; dispose of through your institution's chemical-waste route.
Regulatory status
Research chemicals may lawfully be sold for laboratory research in the United States; they are not approved drugs. See Are research peptides legal?.
Storage and Shelf Life
Store sealed, dry and away from light at room temperature unless the pack states otherwise. The listing does not state a shelf life; the batch documentation does.
Sildenafil Citrate Compared With Related Research Compounds
These are the compounds most often run alongside Sildenafil Citrate in the same research area. Each is a different molecule with its own listing and certificate; none is a substitute for another, and blends do not let you attribute an effect to one component.

What a Good Certificate of Analysis Looks Like
Every lot ships against an independent third-party certificate matched to the batch number on the vial. Check four things when it arrives: the batch number on the certificate is the one on your vial; the RP-HPLC trace shows one dominant, symmetrical peak rather than a cluster of satellite peaks; the mass-spectrometry line reports an observed mass consistent with the compound; and the testing laboratory named is not the synthesis partner. Purity is the peak-area percentage of that trace and does not describe net peptide content by mass, which is reported separately where available. Look any batch up in the COA library.
When Not to Use a Lot, and When to Contact Us
Do not use material whose batch number does not resolve to a certificate, whose lyophilisate has collapsed into a sticky or discoloured mass (moisture ingress), or whose reconstituted solution is cloudy or holds visible particulates after standing. Photograph the vial and contact us within seven days of delivery: transit damage, certificate mismatch and out-of-specification material are replaced or refunded in full. See our refund policy.
Frequently Asked Questions
Is the product photograph the actual item?
The images previously attached to this listing showed a different product under a different brand and were removed; the listing currently uses representative catalogue imagery. The batch documentation identifies the lot.
What does 99% purity mean, and where is it stated?
Purity is the peak-area percentage of the target compound in a reverse-phase HPLC chromatogram at UV 214 nm. It is a lot-specific value reported on the certificate of analysis for the batch number on your vial; this page does not assert a purity for your lot, the certificate does.
Is this for human or animal use?
No. For research purposes only. Not for human consumption. It is a laboratory research chemical and is not intended to diagnose, treat, cure or prevent any condition.
How fast do orders ship?
Orders confirmed before 2:00 PM CT Monday to Friday dispatch the same business day with tracking. Lyophilized peptides are stable at ambient temperature in transit; cold-pack is available on request.
