| * <div>Azidomorphine - 40x potency of M with high affinity to μ</div>
| |
| * <div>Myrophine* - Morphine + 3-benzyl & 6-myristyl chain and acts as a prodrug to M. Has a slow onset of effects and longer duration but reduced potency. Does NOT produce addiction or dependance regardless of dose.</div>
| |
| * <div>6-MDDM - 80x potency of M, faster onset and less body load</div>
| |
| * <div>Dipropanoylmorphine - Ester of M used to treat severe pain. Rarely used but considered to be safer and less adictive than M. As such carries less side effects, such as euphoria. Slower acting, longer lasting and slightly more potent than M.</div>

| |
| * <div>Alfentanil - 1/4 the potency and 1/3 the duration of fent but 4x quicker onset. The businessman's lunch of opiates.</div>
| |
| * <div>Betahydroxythiofentanyl - one of the more favoured fent. analogues by addicts, implying euphoria.</div>
| |

| |
| * <div>AH-7921 - Selective μ agonist, with 80% potency of M. distributed as an RC, TRs show that it has very little euphoria, indicating euphoria comes from somewhere else. Perhaps sigma? Other opioids are heavily potentiated by it. Perhaps μ agonism is purely analgesic and high comes from a combination of μ & δ with each multiplying the affect of the other. This indicates ultimate opiate high would be moderately selective δ agonist</div>
