There isn't. One isn't more bioavailable than the other.
Oh okay..

The difference between the 2 forms of D-Aspartic acid and Di-Sodium-D-Aspartic acid are the chemical structure, absorption,and bioavailability in the human body. My experience is the solubility of the latter form is at least 5 fold greater and the net effect is totally different. Keep in mind that many amino acids are not very soluble and therefore do not always give the consumer the effect that they are hoping for. Formulation is the key

D-aspartic acid is a nonessential amino acid that plays an important role in the neuroendocrine system and development of the nervous system.
While it is less bioavailable than L-aspartic acid, recent research indicates D-aspartic acid plays a role in regulating the release and synthesis of testosterone. It has become a popular dietary supplement among strength athletes like bodybuilders and weightlifters attempting to boost sports performance
Here are two articles from the US National Library of Medicine and National Institutes of Health about D-Aspartic Acid.

Abstract
BACKGROUND: D-aspartic acid is an amino acid present in neuroendocrine tissues of invertebrates and vertebrates, including rats and humans. Here we investigated the effect of this amino acid on the release of LH and testosterone in the serum of humans and rats. Furthermore, we investigated the role of D-aspartate in the synthesis of LH and testosterone in the pituitary and testes of rats, and the molecular mechanisms by which this amino acid triggers its action.
METHODS: For humans: A group of 23 men were given a daily dose of D-aspartate (DADAVIT) for 12 days, whereas another group of 20 men were given a placebo. For rats: A group of 10 rats drank a solution of either 20 mM D-aspartate or a placebo for 12 days. Then LH and testosterone accumulation was determined in the serum and D-aspartate accumulation in tissues. The effects of D-aspartate on the synthesis of LH and testosterone were gauged on isolated rat pituitary and Leydig cells. Tissues were incubated with D-aspartate, and then the concentration (synthesis) of LH and cGMP in the pituitary and of testosterone and cAMP in the Leydig cells was determined.
RESULTS: In humans and rats, sodium D-aspartate induces an enhancement of LH and testosterone release. In the rat pituitary, sodium D-aspartate increases the release and synthesis of LH through the involvement of cGMP as a second messenger, whereas in rat testis Leydig cells, it increases the synthesis and release of testosterone and cAMP is implicated as second messenger. In the pituitary and in testes D-Asp is synthesized by a D-aspartate racemase which convert L-Asp into D-Asp. The pituitary and testes possesses a high capacity to trapping circulating D-Asp from hexogen or endogen sources.
CONCLUSION: D-aspartic acid is a physiological amino acid occurring principally in the pituitary gland and testes and has a role in the regulation of the release and synthesis of LH and testosterone in humans and rats.

Abstract
D-Aspartic acid (d-Asp), an endogenous amino acid present in vertebrates and invertebrates, plays an important role in the neuroendocrine system, as well as in the development of the nervous system. During the embryonic stage of birds and the early postnatal life of mammals, a transient high concentration of d-Asp takes place in the brain and in the retina. d-Asp also acts as a neurotransmitter/neuromodulator. Indeed, this amino acid has been detected in synaptosomes and in synaptic vesicles, where it is released after chemical (K(+) ion, ionomycin) or electric stimuli. Furthermore, d-Asp increases cAMP in neuronal cells and is transported from the synaptic clefts to presynaptic nerve cells through a specific transporter. In the endocrine system, instead, d-Asp is involved in the regulation of hormone synthesis and release. For example, in the rat hypothalamus, it enhances gonadotropin-releasing hormone (GnRH) release and induces oxytocin and vasopressin mRNA synthesis. In the pituitary gland, it stimulates the secretion of the following hormones: prolactin (PRL), luteinizing hormone (LH), and growth hormone (GH) In the testes, it is present in Leydig cells and is involved in testosterone and progesterone release. Thus, a hypothalamus-pituitary-gonads pathway, in which d-Asp is involved, has been formulated. In conclusion, the present work is a summary of previous and current research done on the role of d-Asp in the nervous and endocrine systems of invertebrates and vertebrates, including mammals.

Good post bro! Let us know which one you go with! If you log it as well. I've used three so far being PP's TCF-1, Athletix Formula x, and Southland's recourse. Tcf-1 is my fav as it works and taste amazing.

Any benefit while on a AAS cycle?

Hmm depending on dose and what on IDK. I am on trt all be it 200mg but took it once for 6 weeks while on Athletix Formula x. I had good results but can't really say if it helps when on a AAS.
