Description
Tadalafil liquid is Tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor, supplied as a 30mL liquid at 30mg/mL (900mg per bottle). This batch tested at over 99.9% purity. It’s sold for laboratory research only.
Tadalafil at a glance
Tadalafil is a PDE5 inhibitor developed by ICOS and Eli Lilly and approved in 2003 as Cialis. It’s also approved for pulmonary arterial hypertension (as Adcirca) and for symptoms of an enlarged prostate.
Its half-life is about 17.5 hours, much longer than sildenafil’s, which is why it’s the PDE5 inhibitor of choice in longer research protocols.
How Tadalafil acts in the lab
Nitric oxide makes smooth muscle cells produce cGMP, which relaxes the muscle and widens blood vessels. PDE5 is the enzyme that breaks cGMP down and ends the signal.
Tadalafil blocks PDE5, so cGMP lasts longer and the relaxation is stronger. It only boosts an existing nitric oxide signal and doesn’t start one on its own. PDE5 is concentrated in the penis, the lungs’ blood vessels and the prostate.

Published Tadalafil studies
Clinical trials cover erectile dysfunction, pulmonary arterial hypertension and benign prostatic hyperplasia. The PHIRST trial (Circulation, 2009) reported better exercise capacity in pulmonary hypertension.
Lab research uses it to study the nitric oxide and cGMP pathway in blood vessels, heart muscle and other smooth muscle.

How Tadalafil compares
Tadalafil liquid is easier to place once you see it next to the compounds it’s usually compared with. Tadalafil blocks PDE5 to boost the nitric oxide and cGMP signal. The others:
- Clenbuterol is a long-acting beta-2 agonist studied for airway and muscle effects
- Finasteride blocks 5-alpha reductase type 2 and cuts DHT
- Ketotifen Fumarate is an H1 antihistamine that also stabilizes mast cells
- Pramipexole is a dopamine agonist with a preference for D3 receptors
These liquids don’t share a research area. Each is a well-characterized approved drug from its own class, sold here as a reference compound for lab work. See them all on our research liquids page.
Working with Tadalafil liquid
The concentration is 30mg/mL, so the math is simple: every 1mL holds 30mg, and every 0.1mL holds 3mg. The whole 30mL bottle holds 900mg.
Most labs measure with a 1mL measuring dropper marked in 0.1mL steps. The dropper built into the cap is handy for transfers but not precise enough for measuring.
How to store Tadalafil liquid
Room temperature is fine for Tadalafil liquid. Keep it upright, capped and out of the sun, and write the opening date on the label.
Tadalafil liquid quality and batch records
Our Tadalafil liquid batch measured over 99.9% pure by HPLC with mass spectrometry confirming the identity. We print the real number, so you know what’s going into your experiment.
The label on each bottle shows the compound, the strength and the batch. Ask us for the certificate of analysis for your batch and we’ll email it over.
If a result looks off, check the batch number first, then your handling notes. Most problems with Tadalafil come from storage or mixing, not the material.
