information about the yield percentage of methamphetamine from ephedrine and pseudoephedrine

A mole represents a fixed number just like a dozen or a kilo, but a mole is a huge number used to measure the mass or
weight of a fixed number of atoms or molecules. One mole is 6.02 x 10 to the 23rd power, or 602 with twenty one more
zeros after it. One mole is a 24 digit number. One pseudoephedrine molecule has 10 carbon, 15 hydrogen, 1 nitrogen
and 1 oxygen atoms in it. (C10,H15,N1,O1) One mole of pseudoephedrine has 10 moles of carbon (120g),15 moles of
hydrogen (15g), 1 mole of nitrogen (14g), and 1 mole of Oxygen (16g) which added together equal 165 grams. One
molecule of methamphetamine is C10,H15,N1. One mole of methamphetamine is identical to one mole of pseudoephedrine
minus the 1 mole of oxygen (16g), so one mole of meth is 149 grams. 149 is 90% of 165 grams.

What are the differences between Ephedrine and Pseudoephedrine Chemicals ? Source: tellychemicals@protonmail.com , 4anpp powder NPP sale
Ephedrine and pseudoephedrine are both alkaloids found in the plant Ephedra and are used in medications primarily for their effects on the respiratory system. Despite their similarities, there are several important differences between the two compounds: Supplier contact::Signal::00 91 931 966 8540

What are the differences between Ephedrine and Pseudoephedrine Chemicals ?
Ephedrine and pseudoephedrine are both alkaloids found in the plant Ephedra and are used in medications primarily for their effects on the respiratory system. Despite their similarities, there are several important differences between the two compounds: Supplier contact:Signal:00 91 931 966 8540
### Chemical Structure - 
*Ephedrine:** 
Ephedrine has the chemical formula C10H15NO. It exists in two enantiomeric forms (d and l-ephedrine). - 
**Pseudoephedrine:
** Pseudoephedrine, with the chemical formula C10H15NO, is a stereoisomer of ephedrine, meaning it has the same molecular formula but a different spatial arrangement of atoms. 
###
tellychemicals@protonmail.com
Pharmacological Effects - 
**Ephedrine:
** Ephedrine is a central nervous system stimulant. It has both alpha and beta-adrenergic agonist activity, which means it can increase heart rate and blood pressure, and cause bronchodilation (widening of the air passages in the lungs). -
 **Pseudoephedrine:
** Pseudoephedrine is primarily
used as a decongestant. It mainly has alpha-adrenergic activity, leading to vasoconstriction (narrowing of blood vessels), which reduces nasal congestion without significantly increasing heart rate or blood pressure. 

### Medical
Uses -
 **Ephedrine:
** Ephedrine is used to treat hypotension (low blood pressure) during anesthesia, nasal congestion, and sometimes for weight loss and athletic performance enhancement due to its stimulant properties. - 
**Pseudoephedrine:
** Pseudoephedrine is commonly found in over-the-counter medications for the temporary relief of nasal congestion and sinus pressure caused by colds, allergies, and hay fever.

 ### Side Effects - 
**Ephedrine:** 
Side effects of ephedrine can include nervousness, dizziness, headache, nausea, insomnia, and heart palpitations due
o its stimulant nature. - 
**Pseudoephedrine:** Supplier contact:Signal:00 91 931 966 8540
Side effects of pseudoephedrine are usually milder and may include
insomnia, dizziness, and restlessness. It is less likely to cause cardiovascular effects compared to ephedrine. ###
Legal and Regulatory Status - 
**Ephedrine:** 
Due to its potential for abuse and its use in the illicit manufacture
of methamphetamine, ephedrine is regulated in many countries. In the U.S., it is available over the counter but with strict purchasing limits and monitoring. - 
**Pseudoephedrine:** 
Pseudoephedrine is also regulated due to its use in the synthesis of methamphetamine. In the U.S., it is available behind the counter and requires identification to purchase, with purchasing limits imposed. 
### Mechanism of Action -
 **Ephedrine:** Supplier contact:Signal:00 91 931 966 8540
Ephedrine acts by increasing the
release of norepinephrine, a neurotransmitter, which stimulates adrenergic receptors in both the central and peripheral nervous systems. -
 **Pseudoephedrine:** Supplier contact:Signal:00 91 931 966 8540
Pseudoephedrine primarily stimulates alpha-adrenergic receptors,
leading to vasoconstriction and reduced swelling and congestion in nasal passages. In summary, while both ephedrine and pseudoephedrine share some similarities in chemical structure and origin, they have distinct pharmacological effects, medical uses, side effects, and regulatory statuses, reflecting their different therapeutic roles and safety profiles. Clear difference between the 2 substance.
