[QUOTE="DragonBits, post: 186526, member: 18023"] Interesting they did such a study. Things of note: I looked up the [B]term[/B], but not sure why[B] mean resident time[/B] was so different yet they said no significant route differences. The DBS-based PK analysis of serum testosterone revealed a later time of peak testosterone concentration after SC vs IM injection (8.0 vs 3.3 days) but no significant route differences in model-predicted peak testosterone concentration (8.4 vs 9.6 ng/mL) or [B]mean resident time (183 vs 110 days).[/B] They used a 25 mm length needle for subQ, that is almost 1 inch, longer than most people post about when talking about subQ, They suggested it's more practical to spit the dose into two and inject twice in the abdominals. I injected .5 ml HGB mixed with 0.4 ml testos C in adominials with a .5 inch needle, it left a lump under the skin for a week, Not annoying, just noticeable. No doubt 2 or 4 ml would be more signficant. Also of note, most subects still preferred deep IM, it's assumed because of the increaesd pain with the subQ. [/QUOTE]
