5ml is max for larger muscles per Nursing Board publications here and a Stanford Health guide to sites. My take is that the more the ml are short release, the more the total is considered permissible. Long release test (3 months in medical setting) advise 2ml is max for either spot on glute, and should be divided between the tradition upper right cheek and the more presice but more accommodating ipsolateral “3 finger spread” right by femoral cap. So, general recommendations lack, but pain guides advise NOT massaging as it dispersed the medication to a wider area and causes higher rate of absorption. The pain of short esters is no joke. I did 3 in the quad painlessly, and my entire leg was red and stiff for three days. The deeper you (can) go, the better the muscle handles volume. Closer to sub a and the capacity is shit. This gives us the rule: don’t exceed maximums below, adjusted for your muscle mass depth; do inject as you wish within those limits unless it interferes with training.
-traditional on either spot of glute is only 3ml (I hear four is fine...;)
-side glute 4 ml some longer esters advise this as safest.
-deltoid “triangle” 1ml (2 is easy, but I’ve never stretched it more.)
-posterior deltoid 1ml if patient has muscle. I can put a can of Coke with test inside and it would work. Remember, these patients usually are catabolic.

If unsure the muscle runs deep enough: Test by palpitating patient.

This chart is for oncology injections so rapid dispersion is more likely. I’ve seen testosterone manufacturers guide, more or less, as above. I highly recommend the secondary glute location because although small, it is the best suited and actually the standard of recommend care currently. The sciatic nerve is cm away from upper quadrant gluteal site, and I’ve paradoxically had a nurse jab me right in the nerve. Not fun and I’m lucky she didn’t cause permanent damage. Although the granularity on that side makes me bleed bad now no matter what. I’m into high gauge, even 31 insulin with 5/8” needle, for both sites on deltoid at 1-2 ml. Posterior delta can easily handle 3ml for me but a quick jab in the tight fibers of the lateral deltoids is quicker than you’d guess and gets 2ml out of a otherwise painful spot for me. Good to give a few rest days to Ed shot cycles because you’re bound to rotate sites that eventually haven’t healed from repeated confusion and fiber separation scarring/cellulitosis. .

Maybe leave the prop out then bud as you'll be pinning more often, go for the sus 350. Throw some NPP or Deca in there too with the Tren.

You're welcome mate
Quick tip if you ever get inflammation/swelling with high concentration gear: apply a gel ice pack in that spot after the injection for 15 minutes. Works like a charm. Do NOT warm it up. Cryotherapy works by reducing blood flow to a particular area. Acute cold exposure increases anti-inflammatory cytokines (IL-2 and IL-10) which can dampen the inflammatory response and significantly reduce pain, inflammation and swelling.
Heat therapy is best suited for muscle pain or stiffness of another nature.
