I'd agree 7oh damages a lot. It's some nasty shit in high doses for prolonged periods of time like a couple of weeks. It made me breakout like mad, arms and legs going numb constantly and my ears always felt like I was underwater. 7oh can be cool and all but I'd be careful people while you can't OD on it, even high purity powder was extremely hard on my body, even before I got to high doses started having issues when I very first started at doses as low as 60-100mg per day
WARNING going numb is bad I was just in er and admitted 4 days on treadmill etc chest pain tachycardia bp spikes/drops-limbs/fingertips going numb-faint stabbing pains in lungs i thought were 'walking pnuemonia' and just lethargy and feeling like i was dying-i was switched to subs and slowly feel alive with random panic/tachycardia-.
check this out-below- probably why-the numbness/constriction etc. id stop while ur ahead
detox 2 diff say its bad and the er and upstairs nurses etc all said they are seeing hearing very concerning things with cardio etc-
Mitragynines and 7oh Pharmacology profile:
Structurally similar to yohimbine, Activity on μ, δ, and κ receptors, Main activity on μ receptors creating opiate and analgesic effects and physical dependence, Inhibits radioligand binding at central nervous system receptors, Activates descending noradrenergic and serotonergic pathways in spinal cord, Stimulates postsynaptic α2-adrenergic receptors, Blocks stimulation of 5-hydroxytryptamine2A receptors.
high affinity for the α2-adrenergic receptor, moderate affinity for the α1 receptor, 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1F, 5-HT2B, and dopamine D2 receptors, and weak affinity for the 5-HT1E, 5-HT2A, 5-HT5A, 5-HT7, and dopamine D3 receptors. It behaves as an antagonist at α1-adrenergic, α2-adrenergic, 5-HT1B, 5-HT1D, 5-HT2A, 5-HT2B, and dopamine D2, and as a partial agonist at 5-HT1A. Yohimbine interacts with serotonin and dopamine receptors in high concentrations.
μ, δ, and κ are Mu, delta, and kappa opioid receptors and are activated in when using Kratom. Oxycodone binds to the μ-opioid receptor and activates the μ-opioid receptor, whereas it does not bind to the κ-opioid receptor and does not activate the κ-opioid receptor. It's extra-ordinary that Kratom binds and activates all three μ, δ, and κ opiod receptors.
"To delineate more clearly the in vitro pharmacology of kratom, we conducted high-throughput molecular screening of mitragynine activity at central nervous system receptors (Novascreen Biosciences Corp., Hanover, MD, USA); these studies identified that mitragynine extensively inhibits radioligand binding at several central nervous system receptor systems.
*i added l the word (BAD) in lower bullet points/comments -
because they are all bad/hard on the body-
also do a search on reddits for7oh- chest pain etc. it also messes with calcium and potassium channel clamping involved in heart/function rate.
Kratom/7oh exerts opioid and α-2 receptor agonistic effects as well as antiinflammatory and parasympathetic-impeding effects. Here some effects when the α-2 receptor is binded to and activated.
*Suppression of release of norepinephrine (noradrenaline) by negative feedback.(=BAD)can lead to 'adrenal fatigue'
*Transient hypertension (increase in blood pressure), followed by a sustained hypotension (decrease in blood pressure).(=BAD)
*Vasoconstriction of certain arteries(=BAD)
*Vasoconstriction of arteries to heart (coronary artery)(=BAD)
Constriction of some vascular smooth muscle(=BAD)
*Venoconstriction of veins(=BAD)
*Decrease motility of smooth muscle in gastrointestinal tract(=BAD)
*Inhibition of lipolysis(=BAD)
*decline of cognitive functions associated with the prefrontal cortex (PFC; working memory, attention, executive functioning, etc.)(=BAD)
Sedation
Analgesia
NOTE;
ALL THIS CONSTRICTION AND NUMBING ETC. IS ALSO OBVIUOSLY A CLOT FORMATION RISK.
I have also read a mouse study where it ALSO damages amygdala or hypothalmus...
and this sr17018 every1 is using to get off 7oh- is purportedly causing permanant receptor damage-
I cant verify that but i have seen it in warnings.(havent seen science paper/source)
