    What are typical nandrolone plus TRT protocols?

    I tried one injection of NPP one time and started feeling negative mental effects almost immediately. I'm in no hurry to ever try it again.

    DHT Cream Plus Testosterone Propionate = Major Libido Boost

    I have only seen reliable, repeated evidence of reduced serum E2 levels with the use of oral testosterone. Scrotal cream, which often increases serum DHT to 300+ ng/dL, does not typically reduce serum E2 - instead, scrotal cream increases E2 proportionately to testosterone dose (like other...

    DHT Cream Plus Testosterone Propionate = Major Libido Boost

    You want to check E2 before/after. The DHT is going to go way up with both DHT and testosterone. E2 rising will be the giveaway that it's testosterone. My DHT was not any higher with 1 ml of the real alphagels DHT topical than it was with scrotal cream (mid 300s in both cases).

    DHT Cream Plus Testosterone Propionate = Major Libido Boost

    If you have not used test cream on your genitals before, it is very possible to mistake topical DHT for topical testosterone, because both massively increase DHT. The primary difference is that the topical testosterone also makes some E2. This similarity of effects is exactly why a clever...

    Yes, I purchase UGL products. I don't pay much attention to the availability of raw powders - I have never been interested in brewing as that represents a much greater risk. None of the domestic sources I've seen appear to be having any trouble getting raws though, as they continue to produce...

    Inject hCG IM for better results?

    I'm on Cypionate now, so I would need to spend some significant time on the subq protocol to reach the final levels, which I don't want to do right now. Maybe at some point.

    Inject hCG IM for better results?

    No, that is not certain. I personally have only ever observed site leakage with 1/2" IM injections into my delts, never subq regardless of needle length. I asked ChatGPT about this and it mentioned that site leakage is a well known problem with IM injections, which the Z-track injection method...

    Inject hCG IM for better results?

    No, I don't need to do that. Intellectual humility allows me to acknowledge the limits of both my personal and our collective knowledge, and sit comfortably in the space of not understanding the mechanism behind an observed aspect of reality.

    Any Testosterone Propionate Compounding Pharmacies left?

    I just don't buy it. I'm on multiple forums and have yet to see any indication from any reputable source that testosterone supplies are dwindling or threatened. The manufacture of testosterone esters will never cease, because these have legal and legitimate end customers, and some amount of...

    Inject hCG IM for better results?

    We can make that statement more accurate with some qualification: the averages of many patients levels have been reported to be the same, mostly by those with incentives for that to be so. What I would like to see is an independent crossover trial where each patient acts as their own control...

    Inject hCG IM for better results?

    I must remind you that I have personally experienced lower testosterone levels with SC injections than the same dose IM, and I have talked to many people that have experienced the same phenomenon. What you're asking me to do here is agree that the sky is red, because studies funded by a...

    Inject hCG IM for better results?

    SC bioavailability for you would be higher than either injection method in an obese person, but it seems that your IM bioavailability would probably be even higher still: Very interesting. Maybe this is part of the answer? I guess testosterone isn't the only compound that subcutaneous fat...

    Inject hCG IM for better results?

    I've now seen two recent anecdotes of better results injecting hCG IM versus subq: I would encourage people that haven't gotten what they want out of hCG to experiment with this. I'm not sure why this would work better, but let's find out if it does, and then we can speculate as to why later.

    Can blood work be incorrect?? Really confused

    Remember once daily, moderate dosage on the topical for this purpose. If you go 100 mg twice daily on the scrotum, you'll likely have just as high HCT or higher.

    This affected AAS like primo and masteron, not testosterone (which is what we're discussing here), and the reputable vendors simply admitted that they're out of stock on those other compounds rather than sell anything fake. The state of UGL testosterone remains very healthy.

    My protocol managing hct and libido

    Based on this history of responding better to changes, I would guess you will have better libido results with less frequent hCG. What are you doing with hCG currently?

    My protocol managing hct and libido

    I seem to be having better success with hCG producing libido when I take it randomly / sporadically rather than consistently. Like 250 iu taken here and there seems to produce much better results than the 150 iu daily protocol did (15 mg test cyp daily in both cases). I'm starting to think it...

    Starting Fertility Journey After Long-Term TRT – Seeking Insights

    You can also consider adding FSH to the hCG for better results. Enclomiphene is unlikely to do anything useful while you maintain an injectable TRT dosage of 150+ mg weekly. If you want enclomiphene to help in a significant way, that TRT dosage needs to come way down.

    Subcutaneous vs. Intramuscular Testosterone: Do Delivery Methods Affect Blood Health and Hematocrit Risk?

    Great minds! True, manufacturer funded though, and the real world results I've seen sometimes don't agree. I think studies like this one, by groups with no financial incentive to show subcutaneous injections are equally effective, could be very important to shed more light on the issue.

    Ironically, this seems less likely to occur with UGL sources that are frequently subjected to blind Janoshik testing.

    Subcutaneous vs. Intramuscular Testosterone: Do Delivery Methods Affect Blood Health and Hematocrit Risk?

    You know I'm going to do that anyway despite the preemptive warning. Let's test out this explanation with some numbers. Lets say the IM group with a baseline total T of 230.4 ng/dL had an SHBG of 40 nmol/L, and a baseline free T of 3.9 ng/dL. If you think the SC group had a lower SHBG and a...

    Can blood work be incorrect?? Really confused

    My hematocrit is 46% on injections so I haven't needed to worry about this personally. I can tell you that once daily application of topical TRT produces lower HCT levels than injections at comparable peak levels due to the overnight trough. And then, HCT is completely a non-issue with oral...

    The dose doesn't matter, it's how much you absorb that matters, and the resulting serum levels of testosterone. Very common sentiment. I don't think either of these options will be effective. Assuming your levels increase proportionately to your dosage, which they do in most cases, and...

    These are his levels on 20 mg DAILY with hCG on top. Based on these labs, if nothing about the bioavailability of testosterone improves, he would need to double his dose to 40 mg daily or 280 mg weekly to have what I would call decent levels on a daily protocol. If money is no object, his...

    5/16" is subq no matter where you inject. Even if you manage to puncture the muscle, the oil is leaking back out into the subcutaneous layer. I would urge you to leave the 5/16" needles for peptides, hCG, etc, and use nothing less than 1/2", at least until you have normal levels again for the...

    This is a problem. These are only 5/16" long. I would suggest at least half inch length while eliminating love handles from your rotation. I've gone months at a time injecting daily in only the ventroglutes with 30G 1/2" needles, with no issues or scar tissue buildup. You don't need a billion...

    Something is really off here, and I think it relates to the slashes: cyp/enanthate, shallow IM/subQ. With labs this wrong, you need to isolate variables, and eliminate the slashes. I feel like you are either injecting a bunk formula or subQ'ing into some thick "black hole" fat like the love...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
