This is from another forum:
I used to extract and purify the parent compound of the pellets. I also never ever bought premade from pellets as why would I trust that to someone else that I had no control or any knowledge of their process. LOL Other than the very first conversions I always used a crystallization as the final process. This way all I ever had was about as close are you could get to pure tren outside a real lab.
Even to this day I push all AAS thru .22 mic filters just to be safe. Only the AAS I get directly from my pharmacy does not go thru a filter. Take only a bit of time and adds little to over all costs.
Trenbolones possible connection to breathing difficulties and spastic cough from bronchial contractions and spasms. Here is the basic processes that could be the connection of tren to these specific issues.
The effects of trenbolone fat burning qualities in theory in part via prostaglandin formation. Prostaglandins are made by two different pathways(Cyclooxygenase and Lipoxygenase), and considering prostaglandins are a group of about 20 lipid cells, they have contrary function; responsible for stimulating as well as alleviating inflammation(Inflammation stimulation is the rapid metabolism of them expelled through the bronchials), regulate blood flow to particular organs, control ion transport across membranes, modulate synaptic transmission, induce sleep, mediate lipid release, and regulate metabolism is various tissue.
Prostaglandins are synthesized from arachidonate(Lipoxygenase which catalyze the dioxygenation of polyunsaturated fatty acids) in the cell membrane by the action of phospholipase A2. Cyclooxygenase and lipoxygenase pathways, compete with one another to form prostaglandins(as well as thromboxane or leukotriene-leukotriene being a bronchial stimulator),
In the cyclooxygenase pathway, the prostaglandins D, E and F plus thromboxane and prostacyclin are made. Thromboxanes are made in platelets and cause constriction of vascular smooth muscle and platelet aggregation
Leukotrienes are made in leukocytes and macrophages via the lipoxygenase pathway. They are potent constrictors of the bronchial airways. They are also important in inflammation and hypersensitivity reactions as they increase vascular permeability.
Being that prostaglandins from either pathway, are still fatty acids of a group, they mediate lipid release and control tissue metabolization, so fat burning is a luxury of either pathway of formation. . As prostaglandins made from the Cyclooxygenase pathway dictate muscle constriction and platlet aggregation, and the Lipoxygenase pathway dictates bronchial constriction(the main form of expulsion)
Now one possibility to how this ends up at the effect of decrease lung performance. Trenbolone causes the rate of production of prostaglandins to rise.
Leukotrienes are synthesized in the cell from arachidonic acid by 5-lipoxygenase. The catalytic mechanism involves the insertion of an oxygen moiety at a specific position in the arachidonic acid backbone.
The lipoxygenase pathway is active in leukocytes, including mast cells, eosinophils, neutrophils, monocytes, and basophils. When such cells are activated, arachidonic acid is liberated from cell membrane phospholipids by phospholipase A2, and donated by the 5-lipoxygenase-activating protein (FLAP) to 5-lipoxygenase.
5-Lipoxygenase (5-LO) uses FLAP to convert arachidonic acid into 5-hydroperoxyeicosatetraenoic acid (5-HPETE), which spontaneously reduces to 5-hydroxyeicosatetraenoic acid (5-HETE). The enzyme 5-LO acts again on 5-HETE to convert it into leukotriene A4 (LTA4), an unstable epoxide.
Leukotrienes cause allergy symptom in the lungs such as wheezing and shortness of breath. They also as stated above cause the contraction of smooth muscles one being the brochi (bronchial passage ways). This is what is responsible for continued bronchial constriction in asthma. They also indirectly release histamines.
The other possibilities is the correlation of the Cyclooxygenase pathways. Many recognize this by its acronym COX1 COX2 (like heard of COX inhibitors such as the infamous VIOX) They can casue inflammation. If this is targeted in the lungs there could not be the possibility of lung tissue inflammation.
So there you have a few possibilites on the processes as they may have a effect on breathing and even the infamous tren cough.
