    Solvent-free propionate: finally a successful protocol for me!

    That is good to hear. It will be interesting to see your TT/E2 ratio for next blood test. I have had similar low E2 results. As I mentioned above, what I find challenging about the 50 mg/ml concentration is the large volume you need to inject compared to usual. I a slowly getting used to...

    5 PROVEN Ways to Fix Low Libido Fast

    This is incorrect. Morning wood does not necessarily mean you have sexual desire. You can have one, but not the other. That is the maddening part.

    5 PROVEN Ways to Fix Low Libido Fast

    I recall reading many of your posts. Are there any specific dopaminergic drugs that you had libido success with?

    5 PROVEN Ways to Fix Low Libido Fast

    There have been countless posts on this forum from men on TRT who still lack libido including myself. TRT is only part of the libido puzzle (see Madman's diagram)

    Solvent-free propionate: finally a successful protocol for me!

    Anything for sleep! Glad to hear you are not experiencing the itching like before. Thanks to you, I started the solvent-free TP last week. Too early to make any judgements yet. I am using the TP to return to the blended protocol pioneered by @Cataceous using TE+TP ratio of 4:3. FYI, I am...

    Dhea and pregnelone

    Why do you feel the need to add either to TRT? You will see very mixed results around here regarding DHEA and preg

    Sleep deprivation impacts us in various ways

    No question, but it drives me crazy when people say you just to sleep more as if its a choice. For many of us especially those over 50+ years old, sleeping more is simply not possible. Early morning awakenings is a curse to many

    Solvent-free propionate: finally a successful protocol for me!

    Maybe drop the DHEA so you eliminate a variable. Let us know how it goes.

    Solvent-free propionate: finally a successful protocol for me!

    How did you find out that Pharmacom's prop (the 50 mg/ml version) includes ethyl oleate? I cannot find any ingredient list.

    Solvent-free propionate: finally a successful protocol for me!

    Sorry if I missed it Funk, but does your prop contain benzyl benzoate? If so, do you know the amount?

    Good luck on the move. Yes, please post separate thread on low histamine diet. I'm sure there are a few of us here who would be interested.

    Solvent-free propionate: finally a successful protocol for me!

    That's a shame. Are you sure it was the EO? It sounded like you were on the protocol for 4 weeks before the itching started. Prop takes very little time to build up in system so you would think that any allergic reaction would have occurred within the first several days.

    TRT Before and After: Real Transformations

    I agree with this comment, but there is one major problem with elevated levels 24/7 - your sleep will inevitably suffer which will eventually hurt your recovery and hence your athletic performance. Hell, even 700 TT destroys my sleep waking up totally wired at some ridiculous hour. Maybe...

    My results on daily prop 11mg SQ

    Prop is potent. A little goes along way. When I was using straight TP, I would always test at peak like you did (about 4-5 hours in my case). It would be interesting to see trough as well just to understand the swing

    Solvent-free propionate: finally a successful protocol for me!

    Many thanks for this and keep the updates coming. I too experienced some odd side effects with Empower's prop and always suspected the benzyl benzoate (listed as 15% on the ingredient listing).

    Results: SubQ vs IM @ 70mg/week

    Yes thanks. Can you also link to the propionate thread where Readalot was discussing the purity tests? I have often thought the benzyl benzoate was causing me some issues. And it was significant in Empower's formulation: Propionate (100mg/ml): Benzyl Benzoate 15% / Benzyl Alcohol 1% as...

    Less than 50 mg of T per week

    You've got it right - its about how you feel taking into account your priorities. There are inevitable side effects when you push the envelope of what the body is designed to handle. Some guys are willing to do that because they prioritize athletics performance and aesthetics. Other...

    Results: SubQ vs IM @ 70mg/week

    What do you mean by solvent free? Are you referring to prop's ingredient BENZYL BENZOATE? Can you or @FunkOdyssey refer me to the forum thread on this? I have not been following the propionate shortage news.

    Less than 50 mg of T per week

    The one piece of advice I wish I had known before starting TRT years ago is to start low and work your way up gradually instead of the reverse. Overstimulation from supra-physiological doses is common from everything I've read here and experienced firsthand. All of these side effects are...

    Results: SubQ vs IM @ 70mg/week

    I was on straight Prop for several months. Even low dose @ 8mg daily put my TT over 1200. But yes same afternoon crash as you. I even tried 2x daily prop (one morning + one afternoon). I later switched to @Cataceous blend of propionate and enanthate and tried very ratio under the sun. I have...

    Results: SubQ vs IM @ 70mg/week

    Like you, I have experimented a lot with straight propionate, but always returned to enanthate. I would have expected prop to trigger a bigger dopamine rush, but the swing was always too big of a drop. More like a triple expresso for me. There is a happy medium somewhere in between...

    Results: SubQ vs IM @ 70mg/week

    Great stuff thanks for sharing the tests. Key point is that your testing was done at daily trough. Several forum members have noted that IM has higher peak but lower trough. It would be interesting to see what the daily peak was for each (but I know that asking is a lot and I'm certainly too...

    Let's Settle This: Subcutaneous vs. Intramuscular Testosterone Injections

    Yes shoulder delts with 1/2. I use 31 gauge, but injecting very small amount daily. Tip is to rub shoulder vigorously for 30 sec to get the blood moving before injecting.

    Let's Settle This: Subcutaneous vs. Intramuscular Testosterone Injections

    What size needle are you using? I tried 5/16 on shoulders and quads just for the hell of it. Subjectively felt more like subq which makes sense since too shallow for IM. I've read about some guys doing subq on their calves (with pinch of skin). Not sure why you would do that

    Let's Settle This: Subcutaneous vs. Intramuscular Testosterone Injections

    Please use the search function. There are many many threads on this question. As the others have said, experiment with both. It ain't going to kill you. Frequency of injection is a far bigger variable (2x per week versus 3x versus EOD versus daily, etc).

    Stopping trt without a pct?

    I did the same several times. Just fight through the first 2 months and you will be good to go. I always liked the idea of challenging my HPTA system to restart on its own. If nothing else, taking break from TRT gives you perspective on what TRT does and does not offer. BTW, can you give...

    Has anyone successfully kept Hematocrit/Hemoglobin low without donating?

    Difference between daily IM vs daily SubQ?

    I tried using 5/16 for IM and the subjective results were not good. Did not compare well against 1/2". On the larger issue of daily IM versus SQ, I certainly feel better with IM. However, I find it impractical to inject IM every day for years on end. I am low dose like yourself. I have...

    Testosterone Propionate - Gauging How Quickly It Is Peaking Based Off EQ

    I have similar SHBG as you and on 8mg daily tested at 1200 TT @ 4hrs. This is why straight prop is a roller coaster. Hence the blended protocol that @Cataceous pioneered.

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.
