Recently ordered 1.5 inch needles.. While waiting for order checked out local walgreens and to my surprise they sold me syringes no script... The only problem is they are 24g 3/4".
I've done two injections with them and needless to say they are 10 times better than the 1.5 inch. So my question is how do I know if I am injecting deep enough. I've heard that if you inject test sub-q as opposed to IM, the e2 conversion rate is through the roof. Anybody willing to verify? I am pretty lean at about 9.5% bf so I'm definitely hitting muscle, just not sure if its deep enough.
