Just returned on Sunday from a diving trip to Mexico.  Picked up these Testoprim from Cozumel.  (10 packs - 30 amps)
Each pack contains three boxes with an individual amp inside plus 3 syringes (21g - what a bitch).  200mg Enanthate + 50mg Prop
Paid $21 per box for these.  Not the best price.  But in Cancun they are $32.  Cabo San Lucas is $8 (not a typo) but you have to go to 15 different pharmacies just to locate 5-6 packs.  In Puerto Vallarta they are $11 per pack, but in short supply as well.  Mexico City it is $14 per pack or $10 per pack if you buy the whole carton.
