What’s your "sweet spot" for fluid volume per injection?

I usually land between 0.2 and 0.3 ml because that matches the split doses I already know from the pens that hold 0.6 ml total. Going a little higher is fine if you want more liquid, but it really comes down to what each person tolerates. You won’t know until you test it yourself. Bigger volumes do raise the odds of bruising or a lump that slowly disappears as the substance absorbs. Quite a few people run larger amounts, especially with certain compounds.

Under the skin I rarely push past 0.4 ml. Into muscle, anything 3.25 ml or under works okay.

I like 20–30 units, so 0.2–0.3 ml. For one particular compound I double that volume to cut down on the sting. It’s all personal choice in the end.

I’ve gone from 0.22 ml up to 0.65 ml with the same compound. I prefer keeping it under 0.4 ml because the syringe feels easier to handle. When I mix my own I aim for 0.15–0.20 ml so I can finish off the 30-unit syringes and avoid extra cartridges. This is the only one I still draw from a vial instead of a pen.

I try to stay under 0.3 ml because that matches the syringes I have the most of and the volume never feels uncomfortable. I also do a 2 ml shot once a week under the skin and that feels fine too.

I always set the mix so each milligram comes out to 10 units.

For most peptides I keep it between 0.1 and 0.2 ml. The exact amount doesn’t seem to matter much. I just like the 0.3 ml syringes because the markings are easier for me to read.

0.1–0.2 ml covers most peptides for me. My current vial is 10 mg per ml and I’m doing 0.5 ml twice a week, which works fine so far.

It depends on the compound. Right now one of mine is 30 mg per ml so I draw 1 ml and split it for a 15 mg dose. With another I used 1 ml shots. For the hcg I reconstitute 5000 iu into 5 ml so the math stays simple and I end up with 0.25 ml for 250 iu.

Because I use several compounds I mix most of them so each dose is exactly 10 units. That way I can pull multiple syringes at once without double-checking the numbers. A couple things like nad+ don’t work that way.

I administered my second injection using just 0.03 ml. That lines up with the low 1.25 mg amount. I set the strength at 40 mg per ml. It uses less solution overall and the compound went into solution fast with no apparent issues. Getting the final bit out might be tricky though. For the next batch I'm considering splitting into two 0.04 mg shots weekly since I don't want to drop weight and the hunger reduction has been quite noticeable already.

I go with 2 mL for most things. Less liquid works better and cuts down on lumps. With the T60 at 2 mL I get 15 mg in 0.50 units. I really like the T68s myself.

I've gone up to 3.25 cc with no trouble when doing it intramuscular. For sub q it doesn't seem to matter since the 1 cc syringes never even get filled all the way.

I stick to around 0.3 ml at most.

I picked up a box of 100 of those 31 g 8 mm ones the other day. They feel sharp and nice. I tried injecting 2-24 u of R to test them out. The barrel is really thin compared to the .5 and 1 ml versions. They'll mostly be for my wife's AHK-Cu at 2 u then 4 u.

I use anywhere from 10 to 50 units. Under 10 units gets hard to measure and some pens don't push well on sticky carts below that. Over 50 units it's just a lot of liquid that can cause a lump or leak out. The 20-30 range feels like the best balance for accuracy without too much volume. If something is really concentrated I might dilute it more.

I like staying in the 10-20 unit range. That keeps dosing accurate compared to trying something like 1 unit where a tiny bubble or fraction could throw it off.

For anything sub q I keep it within 50 units. The only thing I go over that with is glutathione and I do that IM.

My usual concentrations stay in the 10 to 50 unit range. Glutathione stands out as the sole item I dilute beyond that level. I prepare it at 400 milligrams per milliliter since the powder integrates more smoothly at that strength. This results in 62.5 units when I measure out a 250 milligram portion.

Anything from 0.1 ml up to 1 ml works fine for me. When I can I aim for a 10 mg per 1 ml solution.

I'm on 10 mg but the solution I received was 40 mg in 4 ml so I end up injecting 1 ml each week. The main thing is to push it in slowly. No problems at all with 1 ml shots.

For Lipo-C and NAD+ I fill the syringe a bit past the 100 unit mark. For the low volume ones like 5-amino, AOD, KPV, VIP, BPC and TB I combine them all in one syringe and do the whole thing at once, usually around 70 or 80 units total.
