Following proper methods (using sterile water and 0.2 um syringe filters) SWIM has injected these pills before. The effects, as described, were not worth the effort or cost spent on IV'ing these pills.
The most pronounced effect is an increased heart-rate and discomfort. Sure, there's the typical amp effect, but much less pronounced than the side effects associated with this ROA.
On a side note, there has been some interest in the effects of IV'd Klonopins. SWIM is an adventurous and well supplied fellow, so he's always looking for a mystery to solve. The solubility is listed as 0.1g/mL, so that shouldn't be an issue with 10 mL of solution and 3mg of active compound.
The filtered solution is a very ominous orange color; like melted orange pop sickles.... 1 hr post injection the effects are no more noticeable than had a similar dosage been administered orally.
If you look at the pharmacokinetics, this makes sense. The klonopin is largely bound by serum proteins, and serum concentrations have little correlation with subjective effects. Likely other benzo's are more suited to this ROA, but the lack of a commercially available preparation should have been his first clue that this is a waste of time and materials.
