SUBQ vs IM physiology

[Dwhit]

Could it be that a lot of guys who think they are injecting intramuscularly in the gluteal region are actually injecting subcutaneously?

Because I inject daily, I rotate areas. My favorite injection site is the ventrogluteal, it took awhile to get comfortable with it. I love it now.

This is something I've also wondered about. Especially using insulin needles, I know that the chances of an injection being IM in the glutes are very low. That said, like Vince, many of us rotate injection sites. I primarily inject in the quads/shoulders, and I know I'm getting to the muscle in these areas.

Here is an article that lends support to the idea that there is no difference between subq and IM injections in terms of local estrogen conversion:

I mentioned in my original post that esterified testosterone is not affected by aromatase. I've seen Dr. Saya mention this, and I've seen it posted a few times on various forums, but I just looked, and I cannot find any research to back this up. On the contrary, I found reference to the fact that testosterone undecanoate can be converted to DHT-undecanoate by 5-alpha reductase, followed by conversion to active DHT by esterase. If 5-alpha reductase can recognize an esterified form of testosterone, might the same be true for aromatase? Does anyone have a reference one way or the other?

Length of needle/angle/amount of adipose tissue at specific injection sites will determine whether one is injecting sub-q or im and if anything when injecting im if one does not go deep enough than they usually end up injecting shallow im.

If that were the case no one would need an AI.

What he means is that the ester is not affected by local aromatase at the injection site. Since fat tissue contains more aromatase than muscle, the concern used to be that subcutaneous injections would result in more direct aromatization of the ester, however, most doctors have now concluded that aromatization does not occur until the oil is broken down and absorbed into the blood stream. In other words, it doesn't matter where you inject, the ester will ultimately be "processed" the same way in the end. The same principle applies to older theories concerning local anabolic effects (ie, injecting in a muscle you want to make bigger)

Though this a thread from last year, my experience of seven months using sub q was a mixed bag.

Doing daily shots, 15 mg, my TT was 777, Free T 16 and E2 29. I did have some weight gain(about 7 lbs) but as far as erectile function and libido, I could've been injecting sterile water. Gave up on it for a year, trying to increase T through using high dose vitamin D, along with zinc, selenium, C, A & E. Then, after months of serious fatigue and depression, I gave myself an IM shot of 30 mg before bed. Woke up feeling clear headed and energetic. I went back to my urologist six weeks ago. My labs presented a sad picture. TT 268. Enough said.

Given my experience, he prescribed 200 mg per week and I inject everyday.(My preference) I've gained 13 lbs around the waist.(155 to 168) New labs were pulled and I see him on 10/18. Broke up an anastrozole tablet into tiny pieces, which isn't easy or accurate and take a little piece twice a week. I don't like using it w/o knowing my E2 but I suspect I hyper-aromatise testosterone. I had three days where my libido was quite strong and erections were sporadic. Nocturnal erections are becoming semi-regular. Nice!

I might reduce my daily dose, depending upon the labs and my urologist's opinion, though, this morning, my weight was down 5 lbs. I'm also back on desiccated thyroid, as I have sub-clinical hypothyroidism, as well. FWIW, I'd rather inject IM, using a 30 gauge insulin needle in the shoulders.

Does it matter where you inject with subq? Everything I’ve read says stomach but does it matter?

It doesn't really matter, I think it's more common in the stomach. Most men accumulate fat in the belly.

Thanks Vince! Unfortunately I accumulate most of my fat in the ass and thighs like a woman!

Belly fat is considered the unhealthy fat, very bad for cholesterol. The type of fat that you have is considered the healthy fat.

Thats what I tell my wife, it’s good fat!
