i believe that is the whole idea of the prescription. If you have been prescribed meds by a doctor then who the fvck can do anything about it. I would however not flaunt anything at work or anywhere else but here as steroids are like witchcraft in most ppl's eyes...the last RX is got was from a legitimate lab that also provides me my test through my regular insurance/doctor...as far as its potency/dosage...i never tested it....but saw slight gains on low doses/short cycle so I have no complaints...hope this helps
