These substances are largely unknown, as the vendors either will not or cannot disclose the compounds they contain. What The Tester can tell you is that they are touted as alternatives to the "last RC which was so popular". One would assume this is referring to Mephedrone, but The Tester is reluctant to cast aspersions.

Both powders are a pale green colour, and have a faint smell which is reminiscent of Ammonia. They do not tend to clump together much, nor are they crystalline in appearance.

Other testers have reported effects similar to that of Mephedrone, but less intense in their nature. These effects are stimulation (mental and physical), euphoria, empathy, bruxism (involuntary jaw clenching or grinding of the teeth), nystagmus (involuntary eye movements), increased heart rate, and less commonly vasoconstriction

Sample 1
Supplier: Higher Grow
Amount Tested: 0.5g
Stated contents: Unknown
Marquis test result:
R.O.A: Insufflation
Other notes: Initial pain of insufflation is minimal, but increases with redosing. Taste is bitter to the point of being sickly. Allergy test consisted of very small amount applied to the tongue- no reaction.

Report:Testing is conducted in the safety of The Tester's living room. This substance smells, tastes and looks familiar to The Tester from past experiences and so they are slightly foolhardy regarding doses and total amount consumed. The Tester would like to point out that with any substance this is a bad idea.

Initially, a dose around 25mg is insufflated. This is enough to provide some stimulation, but probably only just exceeding threshold, so 20 minutes later a further 50mg is insufflated. This proves enough to fully cross the threshold and all expected effects are expected- initial stimulation followed by some relatively mild euphoria and very slight bruxism. At this point, because The Tester is positive that they have experienced this substance before several times, the test ceases to be scientific and strays into the realm of recreational.

Redosing works as expected- i.e. increasing the intensity of the effects at higher doses and extending the stimulation. Throughout the course of one afternoon/evening (roughly from 6:00pm until 12:00pm) the whole 500mgs is consumed, although it should be noted that this was not borne of a compulsive desire to redose as is common with some entactogens of this nature.

Afterwards, sleeping is difficult because of minor residual stimulation but not impossible. Sleep is attained by 2:00am, and The Tester wakes up at 11:00am feeling none the worse for wear. The following day proceeds as planned and is not interrupted by any negative side effects.



Sample 2
Supplier: Chemical Dog
Amount Tested: 200mg
Stated contents: Unknown
Marquis test result:
R.O.A: Insufflation
Other notes: As above. Substance is clearly identical to Sample 1.

This time, substance is consumed by the Tester simply to confirm suspicions that this is the same product as Sample 1. Two 100mg doses are insufflated, roughly an hour apart. Once again The Tester wishes to express that this is foolhardy and does not recommend this course of action to anyone else.


Effects are identical to the ones experienced when testing Sample 1, except this time The Tester decides to stop short of consuming the entire sample which is not a difficult decision to come to. The Tester finds this freedom to stop redosing refreshing.
