This is not a hands-on test. Pros and cons below come from the Amazon listing title checked on November 14, 2026, and from the maker pages linked in the text. If a detail is missing, it is not listed.
Spider Chalk's Black Widow page says 4 oz and "plus grip-enhancing rosin." The FAQ says White Widow contains Black Widow's ingredients plus a skin protection agent and an aluminum-free antiperspirant. The White Widow Amazon title says 8 oz. SPORTMEDIQ's title says 8.5 oz and does not mention rosin.
| Question | Spider Chalk | SPORTMEDIQ |
|---|---|---|
| Sizes we can cite | Black Widow 4 oz on the maker page. White Widow 8 oz on the Amazon title. | 8.5 oz on the Amazon title |
| Rosin | Maker says Black Widow adds it, and White Widow includes those ingredients. | Not listed |
| Mineral | Maker says laboratory-grade magnesium carbonate on the Black Widow page. | Not on the title |
| Sports on the titles | White Widow: gym, powerlifting, weightlifting. Black Widow page: CrossFit and weightlifting. | Gym, weightlifting, climbing, gymnastics |
How to choose
- If you are avoiding rosin, Spider's Widow bottles are the wrong pick on the maker's own description. SPORTMEDIQ is not a confirmed rosin-free bottle either. Its title simply does not say.
- If you want a stated large fill, both White Widow (8 oz, title) and SPORTMEDIQ (8.5 oz, title) state one. Black Widow's maker page says 4 oz.

Spider Chalk Black Widow liquid chalk. The title says it is for weightlifting and the gym, made in the USA, and described as lab-grade.
Lab-grade on a title is the brand's wording, not a test run for this site.
