After reading Anon's shitty guide and coming across the supplements part, I inputted those to chatgpt (I know I know) and asked for its "objective opinion", so take it with a grain of salt.

L-Arginine (1000 mg daily)
-Moderate doses (1000–3000 mg/day) may improve mild erectile dysfunction by improving vascular function.
-Best effect when combined with pycnogenol or citrulline, not on its own.
-No proven effect on semen volume.
-Verdict: Might help blood flow slightly, no clear benefit for semen. L-citrulline should be better, since it converts more efficiently to arginine in the body.

Zinc (50 mg daily)
-Zinc is essential for testosterone production and sperm health. But 50 mg is too high for long-term daily use unless you're deficient. This could lead to copper deficiency, immune imbalance, and nausea.
-15 mg/day with food, or short-term 30 mg cycles if under stress.

Pygeum (200 mg daily)
-Some clinical studies support pygeum (Prunus africana) for prostate inflammation, BPH (benign prostatic hyperplasia), and ejaculatory volume, especially in older men.
-May increase seminal fluid secretion via improved prostate/seminal vesicle function.
-Verdict: Mild effect on volume & prostate comfort in men 40+. But unclear benefit for younger men unless they have prostatitis or BPH symptoms

Lecithin (1200 mg daily)
-Seminal fluid is rich in phosphatidylcholine, found in lecithin.
-Lecithin may help liquefy semen and improve its consistency, but evidence is mostly anecdotal or animal-based.
-Some men report benefit for "clumpy" semen or after long abstinence.
-At the end, there's possible minor benefit for consistency or texture. But no strong evidence for increased semen production.

Celery
-Celery contains androstenone and androstenol, but amounts are tiny and poorly absorbed. Also no strong studies linking celery to improved sexual function or semen quality.

Pineapple for taste (this one was a curiosity of mine)
-Semen flavor can reflect diet, especially strong foods like garlic, coffee, alcohol, meat, or asparagus.
-Pineapple (and fruits in general) may mildly sweeten the flavor due to natural sugars and acidity.
-But it’s not instant, and certainly doesn’t change things dramatically.
-Sperm takes ~72–90 days to regenerate, but semen fluid turns over more quickly (days).

Final Thoughts:
-There is no magic supplement that dramatically increases semen volume unless you're correcting a deficiency or treating a specific issue (like prostate inflammation).
-Hydration, zinc status, frequent ejaculation, and sleep affect semen quality more than most supplements.
-For performance, citrulline, magnesium, vitamin D, and stress management are more effective than most internet stacks.
