This is a common problem with pellets. If you go looking for forums on the matter, you will see that it is rather typical for patients to have a similar response somewhere around the 4th and 5th implantation. This stems from poor oversight/management, and design flaws in the pellets themselves. Keep in mind that all pellets are made the same way. This may seem beneficial at first glance, however, what this really means is that “6 months” worth of medication dissolves in a way that sends your levels far too high in the first month, and then plummeting far too fast and low in the next 2-3.
While the adrenal glands still help out with testosterone and progesterone production in later years, the amount supplied is extremely small. The biggest issue that we see is an end to normal estrogen levels when the body converts excess testosterone into estradiol. This causes an imbalance that leads to a condition called estrogen dominance – where estrogen is now unopposed by progesterone and testosterone because their levels have declined. Estrogen dominance leads to weight gain, which further increases testosterone to estrogen conversion.
Addressing this alternative explanation, Townsend and his colleagues have found women in medical school  and law school  are more selective of a future mate’s financial status, not less. Similarly, Wiederman and Allgeier  found college women’s expected income was positively associated with their ratings of the importance of a potential long-term mate’s earning capacity. Regan  found as women’s mate value goes up, so does their insistence on men’s high status and resources (., they “want it all”; see also  ). Having higher personal status and resource-related traits appears not to attenuate women’s preferences for cues to men’s ability and willingness to provide resources. Instead, at least in the USA, women achieving high status themselves appears to make their long-term mate preferences for men’s high status even more intense!
