Going the natural route, this sounds promising.
25 mg CLomiphene alone increases Testosterone at about 200-300ng/dl from base line wich is pretty impressive.... But it increases e2 wit it, so SHBG rises to, and clomiphene by itself already increases SHBG .....so you don?t get the full spectrum bennefetis from a serm alone.......
AIs reduce E2 and generally increase 100-200ng/dl of total test for each 5 points it reduces from E2. wich is pretty impressive too....
on clomiphene alone most people get border line E2 of normal range rising SHBG... so with more e2 we get lower LIBIDO and erectible function improvement because of the competitive action of E2 plus the rise in SHBG.
on AI alone most people get border line normal low e2....wich is good for anabolism sinse we increase total test and increase FREE test even further, but no libido improvements too sinse e2 regulates NO release on the brain just like testosterone....so basically you get high test with the same limp dick.
so what can we do about that??? maybe a stack of low dose serm with low dose AI maybe just the best option...... you get an increased test production of about 200ng/dl from each and keep e2 levels btween 20-30 ( around 25 is best for libido ) keeping SHBG in check so free test can increase even further.

Effects of aromatase inhibition in elderly men with low or borderline-low serum testosterone levels.
Leder BZ, Rohrer JL, Rubin SD, Gallo J, Longcope C.
As men age, serum testosterone levels decrease, a factor that may contribute to some aspects of age-related physiological deterioration. Although androgen replacement has been shown to have beneficial effects in frankly hypogonadal men, its use in elderly men with borderline hypogonadism is controversial. Furthermore, current testosterone replacement methods have important limitations. We investigated the ability of the orally administered aromatase inhibitor, anastrozole, to increase endogenous testosterone production in 37 elderly men (aged 62-74 yr) with screening serum testosterone levels less than 350 ng/dl. Subjects were randomized in a double-blind fashion to the following 12-wk oral regimens: group 1: anastrozole 1 mg daily (n = 12); group 2: anastrozole 1 mg twice weekly (n = 11); and group 3: placebo daily (n = 14). Hormone levels, quality of life (MOS Short-Form Health Survey), sexual function (International Index of Erectile Function), benign prostate hyperplasia severity (American Urological Association Symptom Index Score), prostate-specific antigen, and measures of safety were compared among groups. Mean +/- SD bioavailable testosterone increased from 99 +/- 31 to 207 +/- 65 ng/dl in group 1 and from 115 +/- 37 to 178 +/- 55 ng/dl in group 2 (P < 0.001 vs. placebo for both groups and P = 0.054 group 1 vs. group 2). Total testosterone levels increased from 343 +/- 61 to 572 +/- 139 ng/dl in group 1 and from 397 +/- 106 to 520 +/- 91 ng/dl in group 2 (P < 0.001 vs. placebo for both groups and P = 0.012 group 1 vs. group 2). Serum estradiol levels decreased from 26 +/- 8 to 17 +/- 6 pg/ml in group 1 and from 27 +/- 8 to 17 +/- 5 pg/ml in group 2 (P < 0.001 vs. placebo for both groups and P = NS group 1 vs. group 2). Serum LH levels increased from 5.1 +/- 4.8 to 7.9 +/- 6.5 U/liter and from 4.1 +/- 1.6 to 7.2 +/- 2.8 U/liter in groups 1 and 2, respectively (P = 0.007 group 1 vs. placebo, P = 0.003 group 2 vs. placebo, and P = NS group 1 vs. group 2). Scores for hematocrit, MOS Short-Form Health Survey, International Index of Erectile Function, and American Urological Association Symptom Index Score did not change. Serum prostate-specific antigen levels increased in group 2 only (1.7 +/- 1.0 to 2.2 +/- 1.5 ng/ml, P = 0.031, compared with placebo). These data demonstrate that aromatase inhibition increases serum bioavailable and total testosterone levels to the youthful normal range in older men with mild hypogonadism. Serum estradiol levels decrease modestly but remain within the normal male range. The physiological consequences of these changes remain to be determined.
