GVL Test Kit - Purity Test Kit for GVL
Find GVL purity test kits and reagent tests selected for fast substance identification and cleaner checking. GVL has a density of approximately 1.05 g/mL, meaning 1 mL contains roughly 1050 mg of neat GVL. Animal studies indicate GBL is 5-7 times more potent than GVL, with human anecdotal reports aligning with typical single doses of 3-7 mL and binge totals exceeding 40 mL. Subjectively less euphoric but significantly longer-acting than GBL/GHB, with effects that plateau rather than peak sharply. This leads to misjudgment of redose timing, sometimes called 'slow-J'. Delayed convulsive overdoses have been reported 8-9 hours after a 3 mL redose combined with alcohol.
Drug purity testing kits come in 3 types: reagent tests, TLC and test strips. Use a multi-reagent kit to identify most common substances. Pair reagents with a TLC test kit to discover number and amount (%) of almost all ingredients. Use test strips to rule out fentanyl, nitazenes or xylazine.
